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... Dr. Elena Moretti |

SO Colloquia: Extragalactic survey science in the 2020s: the role of radio continuum observations with the SKA Extragalactic surveys in the 2020s will reveal the full diversity of the galaxy assembly process: from environment-dependent evolution to the build-up of mass inside galaxies, and with a complete accounting of all relevant processes/constituents ensured by multi-wavelength coverage. Observations at radio wavelengths carry a unique potential in that they can probe star-formation activity and cold gas content, i.e. place constraints on both galaxy... Mark T. Sargent |

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... Dra. Carolina Kehrig |

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... Dr. Héctor Cánovas |

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... Dr. Alejandro López Vázquez |

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... Antonio García Muñoz |

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,... Dr. Karan Molaverdikhani |

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... Bárbara Rojas-Ayala |

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-... Dr. Isabel Rebollido |

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... Dr. Ricardo Amorin |

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... Dr. Omaira González-Martín |

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... Bruno Rodríguez Del Pino |

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-...
