CharlaHow to use a cosmological N-body simulation as a theoretical model
A key problem that we are facing in cosmology nowadays is that we cannot make accurate predictions with our current theoretical models. We have all of the...

CharlaHow well does galaxy clustering constrain cosmology?
On the LCDM cosmology, dark matter collapses into virialised objects called haloes. The abundance and distribution of these haloes are a direct consequence of...

CharlaHunting for VIPERS red nuggets - traces of the past
Vimos Public Extragalactic Redshift Survey (VIPERS) is a spectroscopic survey designed to investigate the spatial distribution of ~90k galaxies on redshift 0.4...

CharlaMatter-antimatter sourced dark matter
Cosmological and astrophysical e xperimental data demark a large share of the limits of our knowledge in fundamental physics. I'll review two pieces of evidence...

CharlaOpen questions and Non-Standard models
I will review some theoretical ideas in Cosmology different to the standard "Big Bang": the Quasi-steady State model, Plasma Cosmology model, non-cosmological...

CharlaThe dark side
What's the dark matter made of? Do we have any idea of the kind of particle that should constitute ~85% of the matter content of the Universe? In this talk, I...
