Welcome

 

I'm a Chilean researcher at Centro de Estudios de Fisica del Cosmos de Aragon (CEFCA) in the city of Teruel,  Spain. My research interests include Galaxy formation and evolution, Large Scale Structure, Semi-analytical models, High redshift galaxies and Radiative transfer.Big

My work is mostly concentrated in predicting galaxy properties from hierarchical semi-analytical models of galaxy formation. In particular, I have worked with GALFORM (Durham, UK) and SAG (Argentina-Chile).

I have developed models for nebular emission in star-forming galaxies by combining radiative transfer and photoionisation codes to semi-analytical models. In order to understand the properties of Ly-alpha emitters, I developed a Monte Carlo radiative transfer code of Ly-alpha photons that allows us to predict the escape fraction and line profiles of these photons.

Many large cosmological surveys are currently relying on emission lines to detect galaxies and obtain precise redshift measurements. Hence, I am currently  looking into the properties of these galaxies as tracers of the Large Scale Structure of the Universe, especially at high redshifts.

I'm an active member of the J-PAS survey, an ~8500 square degrees survey of the northern sky with 56 optical narrowband filters. This is going to be carried out in the OAJ observatory that is operated by CEFCA. The survey is scheduled to start by 2016.

I obtained a PhD in 2010 from Durham University, UK, under the supervision of Dr. Cedric G. Lacey and Prof. Carlton M. Baugh. My thesis title is "The Nature of Emission-Line galaxies in Hierarchical Cosmologies", and it's available here.
