SO Colloquium: The evolution of the accretion process: investigating the protostellar phase to constraints planet formation
The accretion process is responsible for the mass building during the star formation phase, but our knowledge of this phenomenon is still not totally understood. On one side, the magnetospheric accretion scenario describes the accretion on pre-main sequence (Class II/III) low-mass stars. However, most of the material is supposed to be accreted during the earliest stages, i.e. the protostellar phase (Class 0/I), when the forming star and its disk...

Studying magnetic fields, dynamics, and fundamental physics near a black hole with current and future mm-VLBI instruments
The Event Horizon Telescope (EHT) has imaged the black hole shadows of the supermassive black hole at the center of the galaxy M87 (M87*) and at the center of the Milky Way (Sgr A*). Polarimetric imaging of M87* with the EHT enabled significantly stronger inferences on the black hole and accretion parameters than total intensity data alone. Geometric modeling was a central tool for studying the structure of M87* and Sgr A* in total intensity. In...

Outflows from low to high luminous AGNs
Outflows are believed to play a major role in the evolution of galaxies and are said to be ubiquitous within the active galactic nuclei (AGN) population. However, we still lack a comprehensive view of their properties and impact in their host galaxies and the surrounding medium. If we focus on the low luminosity part of the AGN family, in particular in low ionisation nuclear emission-line regions (LINERs), the impact of outflows is still largely...

SO Colloquium: Multi-fluid solar chromosphere
The solar chromosphere is the boundary layer between the interior and exterior of the Sun, routing the origins of the coronal heating. New large-aperture solar telescopes, such as the future 4-meter European Solar Telescope or American DKIST, have among their primary focus observations of chromospheric magnetic fields. The correct interpretation of solar data requires sophisticated theories. The solar chromosphere is made of strongly stratified...

The Galactic Center seen with MeerKAT
During its inauguration, the MeerKAT released, to date, the most detailed image of the centre of the Galaxy at L-band (1.28 GHz). Since then, the data have been exploited for various scientific research. One such exploitation was to produce a high resolution mosaic of the Galactic centre. From this mosaic came a catalogue of newly discovered unresolved point sources. Over 1500 sources were identified, of which 20 are steep spectrum point...

SO Webloquium: Feeding and Feedback: How to Make a Starburst and What that Means for the Host Galaxy
The cycle of star formation governs the evolution of galaxies. In some local galaxies, the star formation rate in their centers are much higher than other normally star-forming galaxies and may be more similar to galaxies at earlier cosmic times. I present observational results from two archetypal nearby starburst galaxies: NGC253 and M82. First, I will discuss how gas flows to the center of NGC253 along its bar to fuel the extreme burst of...

SO Colloquium: The demographics of small exoplanets
The diversity of the exoplanet population is beyond our imagination. The more than 5000 known exoplanets vastly differ in mass, size, orbital period, dynamics, and host type. Demographic studies, however, aim to find patterns in the population that inform us about their origin, composition, and evolution. Among these features, perhaps the most surprising is the abundance of planets with no analog in the solar system, also known as sub-Neptunes....

Massive stars are important throughout the universe, but their formation remains poorly understood. I review current understanding of how massive stars form in our Galaxy, in particular examining observational tests of various predictions of Core Accretion and Competitive Accretion theories. Finally, I discuss how massive star formation may have been different in the very early universe and how the first stars may have become supermassive...

A VLTI view of Massive Young Stellar Objects (MYSOs)
The formation of massive stars, objects with masses larger than 8 times solar, is central to both stellar astronomy and galactic evolution. In recent years, significant progress has been made in understanding the formation of high-mass young stellar objects (MYSOs; i.e. M∗ ≥ 8 M⊙, Lbol ≥ 5 x 103 L⊙. The latest observational and theoretical studies present evidence that HMYSOs are born in the same way as their low-mass counterparts, via disc...

Coloquio SO: Extracting stellar populations and (mainly) emission line information out of S-PLUS photometry
We present tests of a new method to simultaneously estimate stellar population and emission line (EL) properties of galaxies out of S-PLUS photometry. The technique uses the AlStar code, updated with an empirical prior which greatly improves its ability to estimate ELs using only the survey's 12 bands. The tests compare the output of (noise-perturbed) synthetic photometry of SDSS galaxies to properties derived from previous (STARLIGHT-based)...

Black holes hold a tremendous discovery potential, and experiments such as the Event Horizon Telescope and its next generation upgrade could provide important cues about their structure. New physics beyond general relativity can modify the structure of black holes and leave imprints on image features, for instance changing the separation between photon rings or generating additional sets of photon rings. Both cases motivate the study of the...

X-ray emission from Symbiotic Stars: a stellar window to the Astrophysics of AGN
Symbiotic stars (SySts) are binary systems in which a white dwarf (WD) accretes material from a red giant star. X-ray studies of SySts reveal an apparent variety of processes which would suggest different origins. In this talk I will briefly review our current knowledge of the X-ray properties of SySts (their classification and physical parameters), in particular I will describe the iconic systems R Aqr and CH Cyg. Finally I will present our...

Near-Infrared Observations of Clustered Massive Star Formation in Outflowing Region AFGL 5180
Massive stars are significant throughout the universe, as they impact their surroundings from the early stages of their formation until they die in the form of supernova. Observations in the near-infrared (NIR) of the bright and large-scale (~pc) jets which young stars ubiquitously produce during their formation process can place important constraints on the phenomenon of massive star formation. Here, we present a detailed NIR view of the star-...

Observational tests of strong field gravity are improving rapidly. This allows us to test whether the compact objects observed in the sky are truly black holes as described in general relativity or some other "exotic" objects. These tests, however, require exquisite theoretical modeling of black holes as well as their alternatives. This talk will discuss two such examples: the impact of the astrophysical environment on black holes and the...

Off-centre supermassive black holes in bright central galaxies
Supermassive black holes (SMBHs) are believed to reside at the centre of massive galaxies such as brightest cluster galaxies (BCGs), the most massive galaxies which can be found in today's Universe. However, as BCGs experienced numerous galaxy mergers throughout their history, the central BH can be significantly kicked from the central region by these dynamical encounters. By combining the Illustris-TNG300 simulations and orbital integration...

Rocky planets located in the habitable zones around very low-mass objects are ideal targets for searching for life outside our Solar System. In order to better understand their formation and evolution, N-body simulations are needed. These simulations are developed assuming a star close to the substellar mass limit as the central object. The simulations include tidal and general relativistic effects that incorporate the contraction and evolution...

SO coloquio: Investigating the impact of quasar feedback on the central kiloparsecs of galaxies
Active galactic nuclei (AGN) feedback is the effect that nuclear activity produces in the interstellar and circumgalactic medium of galaxies. Different modes of AGN feedback, which can be broadly divided into radiative/quasar and kinetic/radio, are now considered key processes in the evolution of massive galaxies by regulating black hole and galaxy growth. Indeed, a wealth of observational evidence demonstrates that feedback from supermassive...

An observational study of massive star forming regions at radio wavelengths
In their early stages, massive stars have a profound impact on their hosting cloud as reflected by signposts like shocks, bars and shells of swept material resulting from prominent stellar winds, or photo-ionized (HII) regions produced by energetic irradiance. This activity must be taken into account in the study of the mechanism of formation of either massive stars or nearby lower mass companions affected by such harsh conditions. It is known...

When accretion is as vital as extreme: from massive young stars to binary black holes
Accretion is vital for understanding the properties of a number of astrophysical objects, including massive young stars and black holes. For the former, accretion drives the stellar mass growth and multiplicity through gas fragmentation. It also powers strong outflows that regulate the interstellar medium. For black holes, only accretion allows for electromagnetic detection. Hence, the multi-messenger astronomy, for which the loudest sources of...

Sub-milliarcsecond astronomy with Imaging Atmospheric Cherenkov Telescopes
The angular size of a star is a critical factor in determining its basic properties. Together with the distance, it provides the physical diameter of the star which can be used to yield luminosity and mass estimates.

This fundamental limitation can be overcome by several methods...

J-PAS: a survey for tracing the role that star formation and environment play in galaxy evolution
The processes that explain the evolution of galaxies from the blue cloud to the red sequence are still under discussion. Internal processes, named as mass-quenching, because they are linked to the galaxy mass or AGN feedback, could be responsible of the rapid quench of the star formation in galaxies. Besides the stellar mass, the evolution of the galaxy populations is also a function of the environment. Unlike the mass quenching, the...

SO Coloquio: Dirty Dancing: piercing the dusty environment of merging supermassive black holes
It is a posit of modern astrophysics that most massive galaxies host a super- massive black hole (millions to billions of times more massive than the Sun). These black holes affect the evolution of galaxies well beyond their gravitational sphere of influence (which does not extend wider than 1/1000th of the typical galaxy linear size). In turn, the evolution of galaxies affects the growth of black holes through, e.g., galaxy merging....
