PublicaciónConfronting fuzzy dark matter with the rotation curves of nearby dwarf irregular galaxies
Aims: In this paper, we carry out a phenomenological investigation of the viability of fuzzy dark matter, which is composed of coherent waves of non-interacting...

PublicaciónConstraining the inner density slope of massive galaxy clusters
We determine the inner density profiles of massive galaxy clusters (M 200 > 5 × 10 14 M ☉) in the Cluster-EAGLE (C-EAGLE) hydrodynamic simulations, and...

PublicaciónConstraints on cosmological parameters from recent measurements of cosmic microwave background anisotropy
We present new results from a study of recent cosmic microwave background (CMB) observations which provide the first strong evidence for the existence of a...

PublicaciónConstraints on the Abundance of Primordial Black Holes from X-Ray Quasar Microlensing Observations: Substellar to Planetary Mass Range
We use X-ray observations of quasar microlensing (sensitive to smaller compact objects than in the optical) to study the possible presence of a population of...

CharlaConstraints on Ultra-Light Dark Matter from Galactic Rotation Curves
Bosonic ultra-light dark matter (ULDM) in the mass range m ~ $10^{-22} - 10^{-21} \rm eV$ has been invoked as a motivated candidate with new input for the small...

CharlaCosmic Microwave Background observations
In the first part of this talk I will present a historical review of the CMB observations, one of the most powerful cosmological probes. Following the first...

CharlaCosmological giants and elves: galaxy formation and the small scale of cold dark matter
I will review the status of our understanding of galaxy formation in the prevailing cold dark matter paradigm. After reviewing the successes and failures of the...

CharlaCosmology on small scales: the structure of (mostly) dark matter halos
The standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...
