Superwinds: galactic hurricanes
Galactic superwinds, common phenomena in galaxies, are capable of releasing an extraordinary amount of energy and transporting material over long distances. Their influence on the host galaxy can be of great importance, to the extent that the formation of these "galactic hurricanes" can even determine the life of galaxies. The study of these phenomena provides us with some keys to solving the enigmas of modern astronomy about the evolution of...

The first image of a black hole
The Horizon Event Telescope (EHT), a planetary-scale telescope made up of eight radio telescopes and forged through international collaboration, was designed to capture the first image of a black hole. In a series of simultaneous international press conferences on April 10, EHT researchers revealed that they had succeeded and showed the first direct visual evidence of a super-massive black hole and its shadow.

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...

Correlations between the size and the stellar population properties of quiescent galaxies
During the last decades, many authors have put large efforts to shed light on the mechanisms responsible of the generalized growth in size of galaxies, as well as to disentangle the main “driver” of their stellar content. In our study, we aim at stating new constraints on the mechanisms that may drive the growth in size of massive galaxies through the study of the stellar population properties of quiescent galaxies within the stellar mass-...

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...

TIDES, PLANETARY WAVES, AND ATMOSPHERIC COUPLING
A growing number of studies report linkages between unrelated stratospheric and upper atmospheric phenomena. For example, stratospheric warmings correlate with ionospheric perturbations, and with reductions in polar mesospheric cloud occurrence. Understanding these so-called teleconnections is important for prediction of the near-space environment, and interpreting global change proxies. Tides and planetary waves are important agents for...

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...

SO Colloquium: Back to Orion
Orion is the massive star formation region closest to the Sun and in consequence it has been studied in detail. I will present three recent results from the IRyA group on this region. The first one is the ultraprecise determination of the distance to Orion using VLBI observations of stars with non-thermal emission. The second result is a study of the kinematics of the stars with either termal or non-thermal emission. Finally, we will focus on...

An ionised bubble before the epoch of re-ionisation
In a search for Lyman Alpha sources around two spectroscopically confirmed star forming sources in the Subaru Deep Field, we have found some 45 low luminosity star forming galaxies. We find that these sources form a proto-cluster. Moreover, they reside in an ionised bubble of at least 12000 cMpc^3.

SO-IAA Colloquium: Neutral and molecular gas outflows as tracers of the impact of radio jets
Our view of the gas and its physical conditions in the central region of AGN has been enriched by the discover of fast and massive outflows of HI and molecular gas. These outflows can be driven by radiation/winds but also by the interaction of the radio plasma with the ISM. Understanding the origin and quantifying their impact requires to trace their location and derive their physical conditions (density of the gas, mass, mass outflow rate and...

Nonlinear dynamics of space and astrophysical plasmas
Solar atmosphere and solar wind provide a unique laboratory for understanding the nonlinear dynamics of space and astrophysical plasmas. A quantitative analysis of the reconnection condition and the degree of intermittency reveals that rope–rope magnetic reconnection is the most likely site for genesis of interplanetary intermittency turbulence in this event. The dynamic pressure pulse resulting from this reconnection triggers the onset of a...

Signatures of a jet cocoon in early spectra of a supernova associated with a gamma-ray burst
Thanks to a detailed observational monitoring and an accurate spectral synthesis analysis of the early phases of SN 2017iuk, we conclude that these features originate from the mildly relativistic hot cocoon that is generated by the GRB ultra-relativistic jet, while it is expanding and decelerating into the medium surrounding the progenitor star.

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...

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...

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...
