My current research focuses mainly on :
- formation and evolution of galaxies
- groups and clusters of galaxies
- galaxy structure and morphology
Galaxy Evolution in the Group Environment
For my Ph.D. Thesis (supervised by
Prof. C. M. Carollo) I
am studying how and to which extent
galaxy properties are affected by the environment in which they reside.
To address this problem I am using the ZENS
(Zurich Environmental Survey), an ESO Large Program at the wide-field imager at la Silla. The survey consists of 141 galaxy groups at
redshift z=0.05 with more than a thousand member galaxies down to
a magnitude of bj=19.5. I have the carried out all the data reduction,
analysis and database construction for the survey.
For the galaxies in the ZENS sample I have measured several properties:
- Galaxies morphology and structure (e.g. frequency of galactic sub-components)
- Galaxies
photometric parameters (e.g. colour profiles, location and extent of the star forming regions)
- Signatures of galaxy interactions (presence of tidal tails and distortions)
- Galaxies derived dynamical properties
Using the above derived
quantities I am able to study in detail the connection between the galaxy
assembly history and the accretion and evolution inside the group potential.
I
am currently investigating several aspects of the 'environmental
problem': (i) is there any residual environmental effect on galaxy
properties beyond the one that can be ascribed to a mass-density
relation? (ii) do 'normal' and first ranked galaxies follow
different
evolutionary paths? (iii) is the so-called "pre-processing" in groups
necessary to explain the observations and is it effective at any group
mass scale?
Using the wide distribution of location of the ZENS groups onto the large scale structure, we
compare properties of galaxies in different environments not only in a
"local" sense but also in connection to the hierarchical formation of
the cosmic web.
Publications from the work I have done for my thesis will be published shortly.
During my PhD I have supervised these master and semester students:
Master Thesis
'The effects of tidal interactions in local galaxy groups' - A. Sippel (2009)
Semester projects
'Optimizing signal-to-noise ratio using Voronoi tessellation' - M. Maturo (2009)
'Search for barred galaxies in COSMOS' - K. Franke (2009)
