The RoboPol Program: Optical Polarimetric Monitoring of Blazars
Blazars are a subclass of Active Galactic Nuclei with relativistic jets pointing at us. For this reason the highly amplified polarized synchrotron emission from their jets dominates in the optical band. Typically, the electric vector position angle (EVPA) of the optical polarized emission in blazars varies in an erratic way. However, in rare cases the EVPA displays long, smooth and monotonic rotations. Being puzzled by this phenomenon missing a...

Search for MIlli-LEnses (SMILE) to discriminate between dark matter models
Projects aimed at characterising dark matter properties make use of very different approaches. One such approach is to look for strong gravitational lens systems. Gravitational lensed images with angular separation on milliarcsecond scales probe gravitational lens systems where the lens is a compact object with mass in the range 10^6-10^9 solar masses, i.e a supermassive compact object (SMCO). This mass range is particularly critical for the...

The continuous rise of bulges out of galactic disks
A tantalizing enigma in extragalactic astronomy concerns the chronology and driving mechanisms of the buildup of the central luminosity excess (bulge) in spiral galaxies like our Milky Way, i.e. in systems referred to as late-type galaxies (LTGs) in the Hubble classification scheme. The standard scenario envisages a two-phase galaxy formation process, with the bulge assembling first in a quick and violent quasi-monolithic episode, with the disk...

The miniJPAS survey: the galaxy populations in the miniJPAS cluster mJPC2470-1771
Galaxy clusters are one of the largest structures in the Universe. Due to the interaction among the galaxy members, they are a great laboratory to study the role of the environment in galaxy evolution. J-PAS survey will soon start to scan thousands of square degrees in the sky, and with its large great field of view (4.2 square degrees) and filter system (56 narrowband filters and 4 broadband filters in the optical spectral range) will provide...

Unveiling the dynamical stage of galaxy clusters through the intracluster light
The intracluster light (ICL) is the most unexplored component of galaxy clusters. It is defined as a low surface brightness, extended emission composed by stars that are bound by the potential of the cluster but do not belong to any galaxy in particular. Simulations predict that minor and major mergers can mainly drive the formation of ICL, specially for z

SO Webloquio: Unveiling the unseen magnetized universe with MeerKAT
Galaxy clusters are known to harbour magnetic fields, the nature of which remains unresolved. Intra-cluster magnetic fields can be observed at the density contact discontinuity formed by cool and dense plasma running into hot ambient plasma, and the discontinuity exists near the second brightest galaxy, MRC0600-399, in the merging galaxy cluster Abell 3376 (redshift 0.0461).

La navegación astronómica y los instrumentos náuticos a través de la historia

The PUMA project. Mergers and feedback in local ULIRGs resolved by ALMA and MUSE+AO
Galaxy mergers and interactions have a key role in the evolution of galaxies, specially at high-z when they were more common than today. Mergers trigger starbursts and AGN activity, which are both regulated by negative feedback processes, as well as can turn spiral galaxies into massive quiescent objects. The local counterparts of these major interactions and mergers are local ULIRGs (L(IR)/Lsun > 1e12) which, thanks to their proximity, allow...

X-ray binary accretion states in AGN? Sensing the accretion disc of supermassive black holes with mid-IR nebular lines
Accretion states, which are universally observed in stellar-mass black holes in X-ray binaries, are also anticipated in active galactic nuclei (AGN). This is the case at low luminosities, when the jet-corona coupling dominates the energy output in both populations. Previous attempts to extend this framework to a wider AGN population have been extremely challenging due to heavy hydrogen absorption of the accretion disc continuum and starlight...

K-band interferometric imaging of the M-type Mira star ‘R Car’
The final stage of low to intermediate-mass stars, also known as the asymptotic giant branch (AGB), presents circumstellar envelopes (CSE); however the mechanisms that lead to the formation of these structures, at least in M-type AGBs, are still not well understood. In order to grasp the characteristics of the CSE, it has been found that the CO molecule plays an important role due to its stability against dissociation, making it a tracer of the...

Is the Bremer Deep Field Ionised at z=7?
The talk will show that the population of star forming galaxies in the Bremer Deep Field (BDF) has formed two large ionised bubbles. The sources in the BDF have been completed with a set of expected, though not detected, low luminosity sources at z ~ 7. We have estimated the number of ionising photons produced per second by the different star forming galaxies in the BDF and have compared it with the number that would be required to reionise...

Archival Spitzer Space Telescope images of most nearby spiral galaxies show prominent 8 micron emission cores when viewed with an unsharp mask technique.

From direct imaging to gravitational waves: tracing the life of gas giant exoplanets
In two decades, the field of exoplanet science has undergone nothing short of a revolution. With such a variety of planetary systems detected, the next step in exoplanet research is to characterise the properties of these systems. In this talk I will focus on “life and adventures” of gas giant exoplanets, and present how future space missions such as JWST, ARIEL and LISA will help us understand the nature, formation and evolutionary history of...

Our Galactic Center: A Unique Laboratory for the Physics & Astrophysics of Black Holes
The proximity of our Galaxy's center presents a unique opportunity to study a galactic nucleus with orders of magnitude higher spatial resolution than can be brought to bear on any other galaxy. After more than a decade of diffraction-limited imaging on large ground-based telescopes, the case for a supermassive black hole at the Galactic center has gone from a possibility to a certainty, thanks to measurements of individual stellar orbits. The...

SO web.Colloquio: GRAVITY+, all Sky, High Contrast, Milli-Arcsecond Optical Interferometric Imaging and Spectroscopy
GRAVITY and the VLTI have transformed high angular resolution astronomy with groundbreaking results on the Galactic Center, active galactic nuclei, and exoplanets. The GRAVITY+ project will soon boost optical interferometry to the next level, opening up the extragalactic sky for milli-arcsecond resolution interferometric imaging, giving access to targets as faint as K = 22 mag, and providing ever higher contrast for the observation of...

We’ve never imaged the Sun’s surface from that close. Solar Orbiter will change that
In February 10, 2020, Solar Orbiter, the new ESA's Sun-exploring mission built in collaboration with NASA, was successfully launched atop an ULA Atlas 5 rocket from Cape Canaveral in Florida. Equipped with ten instruments, six for remote sensing and four for in-situ measurements of the solar heliospheric conditions, it will get as close as 0.28 astronomical units (or 42 million kilometres) to the Sun in a mission that can last more than ten...

The power of low activity black holes
It is possible that most galaxies host a black hole at the centre, most of the time this being in a relatively quiescent state. The so-called low luminosity Active Galactic Nuclei are characteristic of this phase. These objects represent the vast majority of the active galactic nuclei (AGN) population in the near universe, and still the least conforming class with the standard AGN scenario. Their low luminosity is at odds with their often...

SO Web-Colloquia: Flaring on the Sun at all scales
The Sun shows activity across a wide range of size and energy scales. We shall take a journey from the smallest scale events to the largest energy releases in the solar system. The energy release is due to the magnetic fields on the Sun and how they interact. Using EUV/UV spectroscopy different layers of the solar atmosphere can be probed in order to understand the physical processes that occur. The EUV imaging spectrometer onboard the Hinode...
