Cosmic butterflies: the product of tempestuous stellar marriages
Planetary nebulae are some of the most strikingly beautiful astrophysical phenomena known, gracing many a glossy-paged, coffee-table book and earning them the nickname "cosmic butterflies". Classical stellar evolutionary theory states that all intermediate mass stars should produce a planetary nebula, forming as the star leaves the Asymptotic Giant Branch and evolves towards the white dwarf phase. While it remains the standard for astronomy...

(Edif C) NoiseChisel and Gnuastro: non-parametric detection and analysis of astronomical targets
Astronomical instrumentation has greatly advanced over the last 40 years: with digital detectors, space telescopes and +8m class ground-based telescopes for example. However, the signal-based detection paradigm (for example from Petrosian or Kron in the 1970s, mostly used as implemented in SExtractor from the mid-1990s) is still the dominant method of low-level data analysis: detection, segmentation and measurements or catalog production. In...

From protostars to planets: the astrochemical link
Protostars accrete their material from the natal cloud through accretion disks. These disks are progressively dispersed by the recently formed star to form protoplanetary discs in which planets are born. Although this process takes a few million years, now we think that the final chemical composition of the gas and dust in the proto-planetary disk is to a large extent determined by the chemical evolution in the natal cloud. Determining the...

Inverse Compton emission revealed by observations up to TeV energies of GRB 190114C
The hunt for Gamma-Ray-Bursts (GRBs) at very high energy (VHE) started more than 20 years ago. A hint of emission was already claimed by Milagrito from the observations of GRB 970417. On 19 of January the Major Atmospheric Gamma Imaging Cherenkov (MAGIC) clearly detected GRB 190114C above 0.2 TeV. This is the first highly significant detection (over 50sigma reached in the first few tens of minutes after the burst) of a GRB at VHE. GRB190114C...

Nebular HeII emission from spatially resolved metal-poor star-forming galaxies
Nebular HeII1640,4686 emission, observed to be more frequent in high-z galaxies than locally, is indicative of far harder ionizing spectrum than that seen in nearby systems. Star-forming galaxies with lower metal content tend to have a larger nebular HeII intensities compared to those with higher metallicities. This agrees with the expected harder spectral energy distribution at the lower metallicities typical in the early universe. Theoretical...

Data mining Gaia DR2: the quest for Pre-Main Sequence Stars (and their discs)
As the birth-sites of planets, protoplanetary discs have become the object of intense study during the last years. Constraining their typical lifetimes, masses and/or sizes is crucial to understand the process of planet formation. These objects are a natural by-product of early stellar evolution, and therefore a high fraction of Pre-Main Sequence Stars (PMS) are surrounded by a protoplanetary disc. The current census of PMS (and discs) has been...

Molecular outflows: evolution, structure and angular momentum
We present a theoretical model in order to explain the formation and the evolution of the molecular outflows associated to protostars. In this model, we assume that the molecular outflow is a thin shell formed by the interaction between a fast stellar wind and a rotating cloud envelope in gravitational collapse. We obtain a set of partial differential equations, these equations are space and time dependent, and describe the physical properties...

SO-IAA Colloquium: Recent advances about the exoplanetary exospheres
The upper atmosphere of a planet plays a key role at protecting the lower altitudes from the effects of energetic stellar EUV and soft X-ray photons and keV-energy precipitating particles. Through a variety of transport processes, the upper atmosphere also participates in the net loss of a planet’s bulk composition into space. As such, the physics and chemistry occurring in the upper atmosphere influence the evolution of a planet over its...

SO-IAA Colloquium: Characterization of (exo)Planetary Atmospheres
Characterization of planetary atmospheres has always been a challenge. While the next generation of facilities, such as ELT, JWST, and ARIEL, will improve our understanding of planetary atmospheres, the number of well-characterized exoplanet atmospheres is expected to remain limited. Large-scale simulations assist us with this shortcoming by predicting the diversity of the planetary atmospheres, connecting the spare observational measurements,...

SO-IAA Colloquium: What's is the metallicity of cool dwarf stars?
Cool dwarfs are the most numerous stars in the Galaxy and they account for most of its baryonic mass. However, they are likely the least understood main sequence stars. Their complex atmospheres, due to their low temperatures and high surface gravities, have made their spectroscopic study a hard task. Until recently, their basic physical properties, such as radii and mass, were poorly constrained due to the lack of empirical data. Stellar...

Detection of Exocomets: The gaseous environment of Main-Sequence Stars
Planetesimals and small solid bodies in general are key to understand the chemical and dynamical evolution of planetary systems. Direct detection outside the Solar System is still not feasible. However, indirect evidences of such bodies as dusty debris disks or the presence of large amounts of gas in the close-in surroundings of main-sequence stars have been collected for over 30 years now. Transient events observed as variable non-...

ANALOGUES OF HIGH REDSHIFT GALAXIES: DISENTANGLING THE COMPLEXITY OF THE GREEN PEAS
Young low-mass galaxies with extreme emission-line properties are ubiquitous at high redshift and they are believed to play a key role in cosmic reionisation and the early growth of galaxies at z>4-6. However, a detailed characterisation of their physical properties, critical for a better understanding of these two outstanding problems, is yet not possible. A unique population of lower-z analogues of these primeval systems, dubbed Green Pea (GP...

Study of the diversity of AGN dust models
The dust component of active galactic nuclei (AGN) produces a broad infrared spectral energy distribution (SED), whose power and shape depends on the fraction of the source absorbed, and the geometry of the absorber respectively. This emitting region is expected to be concentrated within the inner ∼5 pc of the AGN which makes almost impossible to image it with the current instruments. The study the infrared SED by comparison between infrared AGN...

The Arp299 puzzle. Black holes that devour stars
In January 2005, a bright flash was detected in the nucleus of the galaxy in the process of fusion Arp 299-B, which was considered a supernova explosion. However, ten years of observations at different wavelengths have allowed us to witness how the luminous region was lengthening and expanding, and to conclude that it is a jet of material expelled by the galaxy's central super-massive black hole after tearing a star.

Superwinds: galactic hurricanes
Galactic superwinds, common phenomena in galaxies, are capable of releasing an extraordinary amount of energy and transporting material over long distances.

Properties of ionized outflows in MaNGA DR2 galaxies
Feedback originated from star formation and AGN activity in galaxies can have a significant impact on their evolution. The action of feedback leads to several processes that might have a significant effect on the surrounding gas, for example by heating the system, halting or enhancing star formation, or enriching the interstellar medium. Constraining the incidence and properties of feedback events such as ionized outflows is therefore crucial to...

The Orientation of the Collimated Outflows of Planetary Nebula: Independence Day
The discovery of collimated outflows in planetary nebulae (PNe) has changed the paradigm of PN formation. They actively participate in the nebular shaping immediately before or while fast stellar winds and D-type ionization fronts shock and swept the nebular envelope. The general properties of collimated outflows of PNe cannot be studied because projection effects do not allow us to determine their space velocities and linear sizes. The large...

SO Colloquia: Searching extended line-emission objects in wide-field surveys: The IPHAS experience
One of the problems we are facing in the study of evolved low- and intermediate-mass stars such as Planetary Nebulae (PNe) is the lack of completeness. Most known PNe belong to the bright or intermediate part of the luminosity function, leaving out those at the faint end. Any global chemical, kinematical, and physical analysis of the PN population is therefore biased. In 2003 the INT Photometric Halpha Survey started scanning the...

New and existing facilities operating at submm-to-m wavelengths are shedding new light on the formation of planets, black holes, and even the first galaxies. These telescopes provide the test bed for the technological advancements required to build the next generation of large radio telescopes, like the Square Kilometre Array (SKA).

High-velocity Molecular Clouds near the Galactic Center
The central region of our Galaxy contains a huge amount of molecular gas. This region is often referred to as the "central molecular zone (CMZ)". The recent ALMA observations toward this HVCC revealed orbital motions around an invisible massive object, which is probably an intermediate-mass black hole.

THOT: Dating stars
Life, planets, exoplanetary systems, stars, and our galaxy evolve with time, and the best and sometimes only way for understanding this evolution is dating stars. THOT is a Marie Curie Project devoted to gathering and updating all the stellar dating techniques into a single computational tool. In this presentation, I will present some of the most promising techniques for stellar dating, and show the current main contributions of this project (...

What we (don't) know about the trans-Neptunian objects
The first trans-Neptunian object was discovered in 1930 and we waited over 60 years to discover the second one. The discovery of Albion (a.k.a. 1992QB1) enticed the minor bodies community to characterize the new population, called collectively as trans-Neptunian objects (TNOs). Today we know the existence of over 2,000 objects and counting. Nevertheless, it seems that we have reached our technological limitation in terms of observational studies...

Spirals, rings and arcs around evolved stars
We searched the complete archive of the HST and Spitzer to characterise rings and arcs around evolved low-mass stars (AGB stars, proto-PNe and PNe), study their physical properties and address their formation mechanisms. In this talk, we present the observational results of our survey, the predictions of simple radiation-hydrodynamic simulations as well as the future of the project.

Imaging a black hole with the Event Horizon Telescope
We have imaged the shadow of the central black hole in the radiogalaxy M87. This required assembling the Event Horizon Telescope, a global VLBI array observing at a wavelength of 1.3 mm capable of achieving an angular resolution of 20 microarcsecond (uas). We have resolved the central region of M87 into an asymmetric bright emission ring with a diameter of 42+-3 uas, which is circular and encompass a central depression in brightness with a flux...

The planetary nebula HuBi 1, a rebel with a cause
Planetary nebulae, the descendants of low- and intermediate-mass stars, have characteristic onion-like ionization structure, with the highest ionization species closer to the central star. This is true for all planetary nebulae, but HuBi 1, which shows an inverted ionization inner shell. There is a reason for this oddity, a peculiar stellar evolution of its central star, which makes HuBi 1 the missing link of the population of cool C-rich...

Optical spectroscopy of local type-1 AGN LINERs
The Balmer emission originated in the broad line region (BLR) of active galactic nuclei (AGNs) could be either weak and difficult to detect, or even absent, for low luminosity AGNs, as low ionization nuclear emission-line regions (LINERs). This makes LINERs challenging to fit in the AGN unification scheme. Moreover, a long debate can be found in the literature proposing different ionization sources at the origin of optical emission lines and no...

Extreme quasars at high redshift
The study of the AGN accreting close to the Eddington limit (L/LEdd~1) has taken an important role, due to their potential use as standard candles for cosmological applications. With the purpose to understand the physics of extreme quasar, we perform a spectroscopic analysis of a sample of highly accreting quasars at high redshift (z~2–3). Our sample were observed with the OSIRIS spectrograph on the GTC 10.4 m telescope located at the...

The peculiar case of the active galactic nuclei in PBC J2333.9-2343
Under unification schemes, active galactic nuclei (AGN) can be explained by orientation effects. However, some sources show properties at different frequencies that led to incongruent classifications and cannot be explained by such unification scheme. This is the case of PBC J2333.9-2343; its optical spectrum is of a type 2 AGN but its X-ray spectrum does not show signs of absorption, and in the radio it has many features typical of a blazar but...

Physical and statistical properties of High Frequency Peaked blazars
In the class of active galactic nuclei (AGNs), blazars are the most extreme objects, with their relativistic jets closely aligned to our line-of-sight. The emission of blazars is mostly non-thermal, spanning the entire electromagnetic spectrum, and is often linearly polarized providing us with important insights on the magnetic field structure. An emerging radio-loud AGN population is represented by high synchrotron peaked (HSP) blazars,...

Lightning – from Its Base to Space
Lightning has been studied for centuries with surprisingly meager progress since the early breakthroughs of Franklin. There are numerous reasons for this lack of progress: lightning is complex, it is very energetic with large peak power - hard for in-situ probes to survive, it is spatially and temporally sparse – hard to place a sensor in an optimal location. However, modern technological advances and innovations have led to new remote...
