Who am I?
I am an ESO fellow working in the headquarters of ESO in Garching. I was a former PhD student at the Institute for computational cosmology in Durham University. My broad area of research is galaxy formation and evolution.
What do I do?
I am interested in any aspect of galaxy formation and evolution. I have been working in the last years developing semi-analytic models of galaxy formation with particular interest in:
- Active galactic Nuclei: its effects on the galaxy population through feedback and the relation between host galaxy and black hole properties.
- Star formation and supernovae feedback: modelling SF and SN feedback in a multi-phase interstellar medium is challeging, but necessary if we want to go a step further in our understanding of galaxy formation. I develope more realistic models of the interstellar medium and dynamical models of SN feedback to better understand how these processes affect galaxy evolution.
- Gas content of galaxies: within the context of multi-phase ISM, tremendous amount of data is being and will be released describing the gas content of galaxies. I develope models to give a theoretical framework to understand the relation between gas and galaxies.
- Mock catalogues: I also collaborate in the application of semi-analytic models to study the capacity of instruments such as WALLABY, ALMA, LMT, etc.
In the same line, I am also interested in large volume galaxy surveys and the statistical results that can be taken from them. In particular, I have performed statistical studies of the relation between host galaxy and AGN using the Sloan Digital Sky Survey.
Collaborations
I am currently developing code for the Galaxy formation semi-analytic model, GALFORM, in collaboration with Prof. Carlton Baugh, Dr. Cedric Lacey, Prof. Richard Bower, Prof. Carlos Frenk, Dr. John Helly, Prof. Shaun Cole, from the ICC, and Prof. Andrew Benson, from CALTECH. Within the study of the gas content of galaxies and its application to asses the capacity of new instruments, I actively collaborate with Prof. Chris Power, Dr. Han-Sik Kim, Dr. James Geach and Dr. Estelle Bayet.
In the past I also developed code for the Semi-analytic galaxies code, SAG, in collaboration with Prof. Nelson Padilla and Prof. Sofia Cora at PUC, Chile.
Regarding my studies using the Sloan Digital Sky Survey, I collaborate mainly with Prof. Nelson Padilla and Prof. Michael Strauss.
Two-dimension projection of galaxies in GALFORM (Lagos et al. 2011a, 2011b) in the outskirts of a galaxy cluster. The color scheme shows the HI column density.
Same as before, but here the color scheme shows the molecular hydrogen column density, showing that H2 is much more concentrated than HI.
