Unveiling the dynamical stage of galaxy clusters through the intracluster light The intracluster light (ICL) is the most unexplored component of galaxy clusters. It is defined as a low surface brightness, extended emission composed by stars that are bound by the potential of the cluster but do not belong to any galaxy in particular. Simulations predict that minor and major mergers can mainly drive the formation of ICL, specially for z Dra. Yolanda Jimenez-Teja |

Lighthouse Piercing Through the Storm Clouds in Massive Star Formation Massive stars play crucial roles in determining the physical and chemical evolution of galaxies. They shape their environment from early in their protostellar phase when they blast the surrounding with powerful jets, up until their violent deaths in the form of supernova. However, they form deeply embedded in their parental clouds, making it challenging to directly observe these stars and immediate environments. Notwithstanding, their massive... Dr Ruben Fedriani |

SO Webloquio: Unveiling the unseen magnetized universe with MeerKAT Galaxy clusters are known to harbour magnetic fields, the nature of which remains unresolved. Intra-cluster magnetic fields can be observed at the density contact discontinuity formed by cool and dense plasma running into hot ambient plasma, and the discontinuity exists near the second brightest galaxy, MRC0600-399, in the merging galaxy cluster Abell 3376 (redshift 0.0461). Elongated X-ray emission in the east–west direction shows a comet-like... Dr. James Chibueze |

La navegación astronómica y los instrumentos náuticos a través de la historia Al inicio de la época de los grandes descubrimientos y de las exploraciones oceánicas, los navegantes europeos contaban con medios muy poco fiables para emprender una travesía marítima de larga duración (algunas cartas náuticas, una brújula para marcar el rumbo, técnicas rudimentarias para calcular la latitud y, desde finales del siglo XVI, la corredera para calcular la velocidad del barco). A lo largo de los siglos XVI, XVII y XVIII, se produjo... Francisco José González González |

A high-fidelity sky mock of DESI galaxies in the LCDM cosmology By using N-body simulations in which different cosmologies have been assumed and by comparing them with large-scale galaxy surveys, we can constrain cosmological parameters, even ruling out some cosmological models. In this talk I will describe how we use the Uchuu simulation for this purpose. Uchuu is an N-body dark matter simulation that has been created by an international team of researchers from Japan, Spain, USA, Argentina, Australia,... Julia Ereza |

The PUMA project. Mergers and feedback in local ULIRGs resolved by ALMA and MUSE+AO Galaxy mergers and interactions have a key role in the evolution of galaxies, specially at high-z when they were more common than today. Mergers trigger starbursts and AGN activity, which are both regulated by negative feedback processes, as well as can turn spiral galaxies into massive quiescent objects. The local counterparts of these major interactions and mergers are local ULIRGs (L(IR)/Lsun > 1e12) which, thanks to their proximity, allow... Dr. Miguel Pereira Santaella |

X-ray binary accretion states in AGN? Sensing the accretion disc of supermassive black holes with mid-IR nebular lines Accretion states, which are universally observed in stellar-mass black holes in X-ray binaries, are also anticipated in active galactic nuclei (AGN). This is the case at low luminosities, when the jet-corona coupling dominates the energy output in both populations. Previous attempts to extend this framework to a wider AGN population have been extremely challenging due to heavy hydrogen absorption of the accretion disc continuum and starlight...

SO Webloquio: The Milky Way's young substellar population Young clusters and star forming regions are home to a large number of substellar objects with masses below the hydrogen-burning limit at 0.075 MSun. Most of our knowledge about their populations comes from nearby regions (d lower 400 pc), where we find consistent formation rates of 2-5 young brown dwarfs per 10 newborn stars. Brown dwarf theories, on the other hand, predict that high gas or stellar densities, as well as the presence of massive... Dra Koraljka Muzic |

SO Webloquio: Stellar winds and their effects on exoplanets As the wind outflows from a star, it permeates the interplanetary medium, interacting with any planet it encounters. In this talk I will review some recent works on winds of low-mass stars and discuss the impact stellar winds can have on surrounding exoplanets. Compared to the physical interactions known to take place between the solar wind and the solar system planets, the interaction between stellar winds and exoplanets can be significantly...

K-band interferometric imaging of the M-type Mira star ‘R Car’ The final stage of low to intermediate-mass stars, also known as the asymptotic giant branch (AGB), presents circumstellar envelopes (CSE); however the mechanisms that lead to the formation of these structures, at least in M-type AGBs, are still not well understood. In order to grasp the characteristics of the CSE, it has been found that the CO molecule plays an important role due to its stability against dissociation, making it a tracer of the... M.Sc.

Is the Bremer Deep Field Ionised at z=7? The talk will show that the population of star forming galaxies in the Bremer Deep Field (BDF) has formed two large ionised bubbles. The sources in the BDF have been completed with a set of expected, though not detected, low luminosity sources at z ~ 7. We have estimated the number of ionising photons produced per second by the different star forming galaxies in the BDF and have compared it with the number that would be required to reionise...

SO WebLoquio: Regularly-spaced 8 micron cores as tracers of the earliest stages of star formation in the spiral arms of nearby galaxies Archival Spitzer Space Telescope images of most nearby spiral galaxies show prominent 8 micron emission cores when viewed with an unsharp mask technique. These cores have the IR colors of young star-forming regions, typically a million years old, behind several tens of magnitudes of optical extinction. They are usually invisible in optical images, and yet the sum of their masses divided by their likely age is comparable to the total star... Dr. Bruce Elmegreen |

SO Webloquio: Star-forming Complexes in Local Mergers and High Redshift Galaxies Disk galaxies at high redshift contain star-forming complexes, or clumps, whose masses and sizes far exceed those of clumps in local non-interacting galaxies. However, our recent Hubble Space Telescope observations reveal that local merging galaxies can form massive clumps like those at high z, with the same range of physical size, surface density, age, and star formation rate. These similarities, combined with the loss at high redshift of low... Dr. Debra Elmegreen |
