This is the first talk of a series of four aimed to discuss about Cosmology. Here, I will review the basic concepts of the standard cosmological model, which...
The statistics of voids as a tool to constrain cosmological parameters: σ8 and Γ
We present a general analytical formalism to calculate accurately several statistics related to underdense regions in the Universe. The statistics are computed...
The Stellar Distribution in Ultrafaint Dwarf Galaxies Suggests Deviations from the Collisionless Cold Dark Matter Paradigm
Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. Here we present evidence suggesting deviations from the collisionless...
The three hundred project: mapping the matter distribution in galaxy clusters via deep learning from multiview simulated observations
A galaxy cluster as the most massive gravitationally bound object in the Universe, is dominated by dark matter, which unfortunately can only be investigated...
The Wendelstein Calar Alto Pixellensing Project (WeCAPP): First MACHO Candidates
We report the detection of the first two microlensing candidates from the Wendelstein Calar Alto Pixellensing Project (WeCAPP). Both are detected with a high...
The Wendelstein Calar Alto Pixellensing Project (WeCAPP): the M 31 variable star catalogue
In this paper we present the WeCAPP catalogue of variable stars found in the bulge of M 31. Observations in the WeCAPP microlensing survey (optical R and I...
The cosmic web is one of the most striking features of the distribution of galaxies and dark matter on the largest scales in the Universe. It is composed of...
Tracing the stellar component of low surface brightness Milky Way dwarf galaxies to their outskirts. I. Sextans
Aims: We present results from deep and very spatially extended CTIO/DECam g and r photometry (reaching out to 2 mag below the oldest main-sequence turn-off and...
Understanding the Cosmic Mass Function High-Mass Behavior
We claim that the discrepancy found between the theoretical predictions for the cosmic mass function and those found in numerical simulations is due to the fact...
