23. Dark Matter: Across the galactic scales and cosmic time

understanding.The discovery of rotation curves of disk galaxies by Rubin et al. (1980) has had far-reaching implications for the fields of astrophysics and cosmology. These findings have introduced the need of an elusive component that astrophysicists have dubbed "dark matter", which is believed to be made up of dark particles that are necessarily beyond the standard model of elementary...

25. Dynamics of Spheroids and SMBHs

By now more than hundred massive black hole (MBH) mass measurements of local galaxies based on stellar or gaseous motion reveal strong correlations of the MBH mass with their bulge properties, such as bulge mass, stellar velocity dispersion (sigma) and light concentration. Determining MBH masses is a challenging procedure and it is not possible to use one single method across the full sample...

41. A new Paradigm for understanding the Dark Matter phenomenon

While observational evidence of the so-called Dark Matter anomaly is growing up with more and more sophisticated measurements, we observe that a pure non-collisional fluid in the central regions of the galactic halos, baryonic matter dominated, cannot explain naturally the observed dynamical features. it was observed surprisingly that the DM cores have substantial correlations with the...

27. Developments in sub-GeV dark matter direct detection: Nanomaterials and Molecules

As the WIMP draws under increasing tension thanks to the ever increasing sensitivity of direct detection experiments, the majority of dark matter parameter space outside of the weak scale remains unexplored. Molecular and nano-scale systems are particularly well-suited to look for sub-GeV DM since their eV-scale electronic transitions may be excited through light dark matter interactions....

26. Dark matter searches with CTA

The study of dark matter (DM) encompasses a wide range of models that have been extensively investigated using accelerators, underground detectors, and astroparticle physics experiments. While numerous approaches have been employed, high-energy astrophysical observations offer distinct advantages in unravelling the nature of DM candidates that are challenging to explore within laboratory...

22. Indirect Dark Matter Searches in Dwarf Irregular Galaxies

Gravitational evidences at different cosmological scales hint towards the existence of a dark component of the Universe, which amounts up to the 85% of its matter density. Several theoretical particle models for the dark matter (DM) predict that they are expected to weakly interact with standard model particles. From these interactions, one of the most promising channels are gamma-rays....
