Dwarf spheroidal galaxies (dSphs) are the most dark matter (DM)–dominated galaxies in the Universe, and as such, they provide excellent targets for testing a wide range of DM theories. In this talk, I will review our current understanding of the amount and distribution of DM in these systems, as inferred from the kinematics of individual stars, and

In the past decades, studies of the Milky Way have entered a golden era of large-scale surveys. The Gaia satellite provides precise positions, proper motions, and parallaxes for billions of stars, while ground-based spectroscopic surveys, such as LAMOST, deliver radial velocities and metallicities for nearly ten million stars. In addition, medium-

Massive stars play a vital role in shaping the cosmic matter cycle and driving galaxy evolution, chemically enriching their host galaxy through their powerful stellar winds. Understanding the physical processes behind these mass-loss events is key to producing accurate model predictions. Despite its importance, stellar atmosphere modelling poses

Los sensores difractivos consisten en una máscara difractiva situada en el plano focal común de un sistema óptico 4-f. Tras este sistema se coloca una cámara que detecta múltiples versiones de la pupila de entrada, cada una con sus frecuencias espaciales modificadas, a partir de las cuales podemos extraer las pendientes del frente de onda. Este

Over the past decade, gamma-ray observations from space-based instruments such as Fermi-LAT and ground-based arrays including H.E.S.S., MAGIC, and VERITAS have provided an increasingly detailed view of supernova remnants (SNRs). Several dozen SNRs have now been detected across the GeV–TeV energy range, revealing a diverse population shaped by their
