SO Web-loquio: Active Galactic Nuclei: fueling and feedback Dynamical mechanisms are essential to exchange angular momentum in galaxies, drive the gas to the center, and fuel the central super-massive black holes. While at 100pc scale, the gas is sometimes stalled in nuclear rings, recent observations reaching 10pc scale, or 60mas with ALMA, have revealed, within the sphere of influence of the black hole, smoking gun evidence of fueling. Observations of AGN feedback will be described, together with the... Dr. Françoise Combes |

X-ray Astronomy for non (X-ray) astronomers Observations of X-rays coming from outside the solar system were pioneered in 1962 by Riccardo Giacconi and colleagues. From that very day, it became evident that X-rays would reveal a very different Universe to that shown by optical or radio telescopes. Indeed, X-rays are typically produced in the environment of black holes, or where the ambient temperature exceeds millions of degrees. X-ray telescopes (which, for good reason, are in orbit)...

Peering into the Dark: Probing the Formation and Early Evolution of Massive Stars This presentation will focus on recent work aimed at understanding the formation and early evolution of massive protostars. The massive (M>8 Msol) stars into which these evolve are the primary drivers of galactic ecosystems. The energy and nuclear processed material these massive stars inject into their enviroment during their lives and ultimately as supernovae, shapes the physical and chemical evolution of the ISM in galaxies. These stars... Dr. Gary Fuller |

SO Web-loquio: Massive black hole binaries in the cosmos Massive black holes weighing from a few thousands to tens of billions of solar masses inhabit the centers of today's galaxies, including our own Milky Way. Massive black holes also shone as quasars in the past, with the earliest detected a mere one billion years after the Big Bang. Along cosmic time, encounters between galaxies hosting massive black holes in their centers have produced binary massive black holes that eventually coalesced by... Dr. Marta Volonteri |

Exploring the origin of gas-rich ultra-diffuse galaxies with HI kinematics Ultra-diffuse galaxies (UDGs) are one of the most discussed topics in extra-Galactic astronomy in the last lustrum given their puzzling properties: they have luminosities typical of dwarf galaxies, but optical scale lengths similar to very massive spirals. This intriguing combination is hard to explain, and up to date the precise formation mechanism of UDGs remains unknown. With the goal of learning more about their origins, our group has... Pavel E.

YOUNG RUNAWAY STARS Most stars have spatial velocities within a few km/s of the average velocity of their surroundings and can be considered to be gravitationally trapped. There are, however, a small number of stars that move at velocities of tens or even hundreds of km/s with respect to their environment and that will eventually escape from there. The archetypal runaway stars are mu Col and AE Aur that escaped in opposite directions from the vicinity of the Orion... Dr. Luis Felipe Rodriguez |

Experiments with MUSE data: Finding SN remnants & other curious sources One of the ways of following up on the success story of CALIFA is to refine the spatial resolution, and MUSE is the tool for that. Its superb image quality allows for a different kind of science. While browsing through emission line images derived from MUSE datacubes, we have spotted a number of compact-looking sources with forbidden line emission ([OIII], [NII], [SII]) in excess of that typical of HII regions. NGC 4030, a late type spiral 30... Dr. Roberto Cid Fernandes |

Cosmic butterflies: the product of tempestuous stellar marriages Planetary nebulae are some of the most strikingly beautiful astrophysical phenomena known, gracing many a glossy-paged, coffee-table book and earning them the nickname "cosmic butterflies". Classical stellar evolutionary theory states that all intermediate mass stars should produce a planetary nebula, forming as the star leaves the Asymptotic Giant Branch and evolves towards the white dwarf phase. While it remains the standard for astronomy... Dr. David Jones |

NoiseChisel and Gnuastro: non-parametric detection and analysis of astronomical targets Astronomical instrumentation has greatly advanced over the last 40 years: with digital detectors, space telescopes and +8m class ground-based telescopes for example. However, the signal-based detection paradigm (for example from Petrosian or Kron in the 1970s, mostly used as implemented in SExtractor from the mid-1990s) is still the dominant method of low-level data analysis: detection, segmentation and measurements or catalog production.

From protostars to planets: the astrochemical link Protostars accrete their material from the natal cloud through accretion disks. These disks are progressively dispersed by the recently formed star to form protoplanetary discs in which planets are born. Although this process takes a few million years, now we think that the final chemical composition of the gas and dust in the proto-planetary disk is to a large extent determined by the chemical evolution in the natal cloud. Determining the... Dr. Asunción Fuente |

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 |

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 |

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 |

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... Dra. Laurence Sabin |

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. Dr. Jose Miguel Rodriguez Espinosa |

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...

Is there still hope for discovering new physics in the Euclid era? The new generation of cosmological surveys like DESI, J-PAS and Euclid will measure the effect of dark energy on the expansion history of the universe. They will obtain optical and NIR spectra for tens of millions of galaxies and quasars, constructing a 3-D map spanning the nearby universe to 10 billion light-years, and will provide an accurate determination of the distance-redshift relation. I will review the latest distance scale measurements... Dr. Francisco Prada |

Stellar Tidal Streams in Nearby Galaxies as Dark Matter Probes Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought to influence galaxy evolution throughout cosmic history and to provide important observational diagnostics of nonlinear structure formation. Thin stellar streams in the Milky Way and Andromeda galaxies are spectacular evidence for satellite disruption at the... Dr. David Martinez-Delgado |

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... Prof. Abraham Chian |

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.

High-velocity Molecular Clouds near the Galactic Center The central region of our Galaxy contains a huge amount of molecular gas. This region is often referred to as the "central molecular zone (CMZ)". The recent ALMA observations toward this HVCC revealed orbital motions around an invisible massive object, which is probably an intermediate-mass black hole. Yuhei Iwata |

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...

El puzzle de Arp299. Agujeros negros que devoran estrellas En enero de 2005 se detectaba, en el núcleo de la galaxia en proceso de fusión Arp 299-B, un brillante destello que se consideró una explosión supernova. Sin embargo, diez años de observaciones en distintas longitudes de onda han permitido presenciar cómo la región luminosa se alargaba y expandía, y concluir que se trata de un chorro de material expulsado por el agujero negro supermasivo central de la galaxia tras desgarrar una estrella.
