The abundance of galaxies in the epoch of reionization (z>6) is dependent on fundamental cosmological parameters, most importantly on the properties of dark matter, such that it can be used as a powerful cosmological probe. In this talk, I will discuss constraints obtained from the deepest HST Legacy Fields observations on warm dark matter (WDM) scenarios: thermal relic WDM, sterile neutrino...
I will introduce the fundamentals of the indirect searches for dark matter, including aspects of both multi-messenger and multi-wavelength detection. I will show both recent results and future prospects for different observatories, e.g. CTA, Fermi-LAT, SKA, MAGIC among others.
Dynamical dark energy (DDE) models have been proposed to address several observational tensions arising within the standard Lambda Cold Dark Matter scenario. Different DDE models, parameterized by different combinations of the local value of the equation-of-state parameter w0 and its time derivative wa, predict different maximal abundance of massive galaxies in the early Universe. We used the...
Dark matter (DM), a large (~85%) non-baryonic and non-relativistic component of the matter density of the Universe, likely consists of one or several so-far undetected particles hypothesized in theories beyond the Standard Model (SM). One of the most promising approaches to shed light on the nature of DM particles is to search for signatures of their annihilation or decay into SM particles...
