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 |
