Dust in protoplanetary disks, (still) that great unknown Planetary systems are a side effect in the formation of a star. Planets are believed to be just simply the last remaining of dusty circumstellar disks which is formed around the protostar at very early stages. Thus, understanding how planets are formed requires to understand how dust evolve in these disks. It is less than ten years that we have the possibility of mapping the dust distribution in protoplanetary disks with great detail with... Carlos Carrasco González |

New possibilities for atmospheric analysis with Monte Carlo In recent years, significant advancements have been made in scientific computing utilizing the Monte Carlo method, particularly at the intersection of two key communities: the heat transfer community and the computer graphics community. The first breakthrough is that the computation time required to solve radiative transfer becomes invariant, whether the ground is described by a single building or thousands of them, whether the 3D clouds are...

The art of astrophysical measurements: An elementary lecture on photon counting and S/N Have you ever dared to understand how many photons are detected by your camera when you are pointing the telescope to the sky? Is the action of the spectrograph fully understood when analyzing those photons? Do typical image formation rules hold when studying the polarization of light? All these are a few examples of questions addressed by researchers when designing instruments, which are later constrained by technological capabilities. This... Dr. José Carlos del Toro Iniesta |

Unraveling the Gamma-ray emission in radiogalaxies and their jets Radio-galaxies are a minority among all extragalactic sources detected in gamma-rays, yet they have excellent potential to study particle acceleration and non-thermal emission in AGN jets. In contrast with blazars, which have jets aligned with the line-of-sight, radio-galaxies have a smaller Doppler boosting factors. The implications are important: First, the distance at which they are detectable in gamma-rays is smaller. Second, the thermal... Mireia Nievas Rosillo |

Coloquio SO: Spectroscopy's Role in Stellar Astrophysics To characterize a star, the stellar fundamental parameters such as mass, radius, metal abundance, and effective temperature should be known. Direct measurements of these parameters, especially for single stars, are quite challenging, and indirect methods are often employed to obtain these characteristics. The most effective method for determining these parameters is spectroscopy, which is an analysis technique of spectra. It allows us to... Dr. Filiz Kahraman Aliçavuş |

Laboratory Research on the Atmospheric Impact of Spacecraft Re-entry Debris: Perspectives and Future Challenges The rapid growth of space debris, especially in Low Earth Orbit (LEO), poses a rising risk to both space operations and Earth's atmosphere. Debris fragments, even minuscule in size, can cause significant damage due to their high orbital speeds. To mitigate risks, controlled re-entry of debris is common practice, but this introduces a new concern: the increasing mass of human-made materials injected into the atmosphere. As satellites and rocket... Dr. Antonio Ocaña |

Journey into the Galactic Heart: Illuminating the Enigma of the Nuclear Star Cluster and the Nuclear Stellar Disc. The innermost regions of most galaxies are characterised by the presence of extremely dense nuclear star clusters, which sometimes appear together with larger stellar structures known as nuclear stellar discs. Understanding the relation between nuclear star clusters and nuclear stellar discs is challenging due to the large distance towards other galaxies which limits their analysis to integrated light. In this context, the Milky Way’s centre,... Francisco Nogueras Lara |
