MOSAIC: the high multiplex and multi-IFU spectrograph for the ELT MOSAIC is the planned multi-object spectrograph for the 39m Extremely Large Telescope (ELT). Conceived as a multi-purpose instrument, it offers both high multiplex and multi-IFU capabilities at a range of intermediate to high spectral resolving powers in the visible and the near-infrared. In this talk I will showcase the key science cases that drive the top-level requirements and the adopted instrument architecture. With a planned first light in... Dr Ruben Sanchez-Janssen |

Stellar population studies in the J-PAS survey The Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) is a large scale multi-filter survey that has started to observe 8500 deg² of the northern sky with 54 narrow-band filters in the optical range (3500-9600Å). In our Galaxy Evolution group at IAA-CSIC, we aimed at developing and testing methodologies in order to perform stellar populations studies using this kind of data. More precisely, I will introduce our SED-... Dr. Luis Alberto Díaz García |

Fundamental Physics From Ground-Based Gamma-Rays Observations Crucial topics in fundamental physics, such as the existence of new particles, or violations of the Lorentz Invariance arising at the Planck scale, can be effectively tackled in the cosmic environment, by means of ground-based observations in the VHE gamma-ray band. This includes both Particle showers detectors, such as LHAASO and Imaging Atmospheric Cherenkov Telescopes, such as MAGIC, H.E.S.S., or the forthcoming CTA and ASTRI Mini-Array. I...

UGR bureocrazy for dummies: PhDs fight back Every year we all wonder about the UGR bureaucracy: did we miss something? how could we have known in advance? Let's face it, it's a mess. To try to help us all, especially those who are just starting, I would like to invite everyone interested to a seminar dedicated to understanding what the PhDs have to go through every year (paperwork related), where to find the proper information, who to contact in case of doubt and how to go through the PhD...

Two decades of observing galaxy M87 show an oscillating jet connected to a rotating black hole The Institute of Astrophysics of Andalusia (IAA-CSIC) participates in the 23-year follow-up of the central supermassive black hole of the galaxy M87. The study reveals that the jet emerging from the centre oscillates, which in turn provides the first evidence of rotation of a supermassive black hole |

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... Laura Hermosa Muñoz |

Young massive clusters in the Gaia era After the detection of gravitational waves and the realisation of the wide diversity among core-collapse supernova explosions, Interest in massive stars has been rekindled. Young open clusters are our natural laboratories to explore the lives and deaths of massive stars, and most of our current understanding comes from their study. Until recently, we have been strongly limited by practical difficulties and small number statistics. Most open... Dr. Ignacio Negueruela |

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)... Dr. Roberto Cid Fernandes |

SO Colloquium: Studying star-formation in 'collisional' galaxies with MUSE Galaxies in pre- and post-collisional stages are an excellent laboratory to study the evolution of galaxies, particularly the triggering and suppression of star formation on galactic scales before and after such interactions. In order to analyze the star formation triggered in these systems, we started a series of studies on 'collisional' galaxies with available integral field spectroscopy (IFS) observations. We use Very Large Telescope (VLT)... Dr. Victor Mauricio A. Gómez González |

SO Colloquium: Testing black hole structure with very-long-baseline interferometry 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... Dr. Raul Carballo |

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... Dr. Jesús Toalá |

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.... Dr. Rafael Luque |

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... Dr. Fiorellino, Eleonora |

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... Dr. Isabella Rammala |

They also help understand how field stars populate the Milky Way. Thanks to Gaia, much progress has been accomplished in finding the tidal arms of open clusters. I will show here that such arms are much longer than previously observed, and that their identification requires... Dr. Henri Boffin |

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... Dr. Rebecca C. Levy |
