Who Is Afraid of the Dark (Energy)? Cosmic acceleration dominates the behavior of the recent universe, with some fundamentally new physics at its heart. Recent data gives a tantalizing suggestion that the dark energy behind it is more complicated than a cosmological constant. Nevertheless, we do know a lot about how to describe dark energy behavior. Data within the next year has great promise to give further insight, and exciting new instruments are being planned. Dr. Eric Linder |

The stellar distribution in ultra-faint dwarf galaxies suggests deviations from the collisionless cold dark matter paradigm Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. I will present evidence suggesting deviations from the collisionless Cold DM (CDM) paradigm. In the standard cosmological model the dark matter (DM) particles are collisionless and, because of this very nature, they develop halos with the characteristic central cusp known as NFW profile. Real galaxies do not show NFW profiles but, rather, have a DM mass... Dr. Jorge Sánchez Almeida |

Un universo de diversidad: historias LGTBI en el mundo de la razón y la ciencia El neurólogo Ben Barres, que murió hace unos pocos años, escribió un texto en Nature muy interesante sobre ciencia y género y en él decía: "The progress of science increasingly depends on the global community, but only 10% of the world’s population is male and caucasian. To paraphrase Martin Luther King, a first-class scientific enterprise cannot be built upon a foundation of second-class citizens." Él era transexual. El mundo de la ciencia,... Dr. Javier Armentia |

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... Dr. Maria Koutoulaki |

SO colloquium: A new digitized age of SETI – interferometric commensal observations and machine learning The search for technosignatures - remotely observable indicators of advanced extraterrestrial life - addresses one of the most profound questions in science: are we alone in the universe as intelligent life? The Breakthrough Listen program is leading the most concerted search for extraterrestrial intelligence (SETI) effort to-date through radio and optical surveys of nearby stars, nearby galaxies and the Milky Way galactic plane, thus...

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-... Sam Crowe |

Aperture Masking Interferometry with the JWST In this talk, I will present how the aperture masking interferometric (AMI) mode of the JWST works. I will describe the main characteristics of this mode. In particular, I will show some of the advantages of the mode complementary to standard imaging and coronagraphic observations. I will also introduce the basic principles of the AMI data analysis, including the extraction of the interferometric observables and their interpretation with... Dr. Joel Sanchez Bermudez |

Solar Orbiter: An example of an international collaboration Solar Orbiter is a space mission of international collaboration between ESA (European Space Agency) and NASA. Solar Orbiter was launched on February 9th 2020 from Cape Canaveral, FL onboard of an Atlas V 411 rocket. This event signified the success of the diplomatic, economical, technological, and scientific effort of many countries and two space agencies to achieve a common goal. The outcomes from this mission will aid to the scientific... Dr. Teresa Nieves Chinchilla |

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... Dr. Freek Roelofs |

Single-photon gig in Betelgeuse’s occultation In the realm of astronomical exploration, cutting-edge technologies are indispensable. Single-Photon Avalanche Diode (SPAD) sensors offer unparalleled precision, enabling the detection of individual photons with remarkable timing resolution. However, the current use of single-pixel SPAD devices poses limitations on spatially-resolved imaging in astronomy. Enter two-dimensional SPAD detectors, revolutionizing observation capabilities and enabling... Dr. Francisco Prada |

SO colloquio: Theoretical models for the formation and evolution of Ultra-Cool Dwarf planetary systems 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... Dr. Mariana Sánchez |

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... Dr. Aline Chu |

SO colloquium: A Light in the Dark - Massive Star Birth Through Cosmic Time 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... Dr. Jonathan C. Tan |

In particular, the determination of chemical abundances for stars at different metallicities and ages provides us with a key insight on how and when the various chemical elements were formed within the Galaxy. The chemical trends observed in different parts of the Galaxy (thin disk,... Dr. Elisa Delgado Mena |

Radio continuum halos in nearby galaxies and the CHANG-ES project About a decade ago, the upgrade from the classic Very Large Array into the EVLA, i.e. the Karl G. Jansky Very Large Array (VLA), made it possible to observe fainter radio continuum emission than ever before. The project Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES, PI: J. Irwin) has allowed us to probe gaseous halos of 35 edge-on galaxies with arcsecond details and faint microJansky/beam sensitivities, and to begin answering... Theresa Wiegert |
