Research track record
---------------------
I have played a major role in the last 10 years in the
planning, execution, and scientific exploitation of several leading
X-ray and multi-wavelength surveys (HELLAS2XMM, COSMOS, CDFS, among
others), which led to world-wide recognized results (see list of
publications).
Most of my work in the past years has been devoted to data
reduction and analysis of X–ray data and multi-wavelength catalogs
in the COSMOS field. I have been involved in the data analysis and
reduction of XMM-Newton observations, leading, among others, to
publications on the X-ray logN-logS (Cappelluti, Brusa et al.
2009), and on the multi-wavelength properties of X-ray sources
(Brusa et al. 2007, 2010). My scientific interest in the COSMOS
field (extended also to the deep observations in the Chandra Deep
Fields, CDFS and CDFN) was mainly the search, the study and the
characterization of the most obscured sources at z∼ 1− 2 and their
host galaxies, both directly selected in the X–rays (Brusa et al.
2003, Brusa et al. 2005, Brusa et al. 2007; Brusa et al. 2009b;
Brusa et al. 2010; Mainieri et al. 2011) or revealed through
stacking analysis in infrared selected samples of candidate
obscured AGN (Brusa et al. 2002, Fiore et al. 2008; 2009; Luo et
al. 2011). More recently, I focused my research on the
high-redshift X-ray selected population (Brusa et al. 2009a,
Civano, Brusa et a. 2011). By means of studying average spectral
properties of deep fields sources, I was also able to exclude a
significant evolution in the equivalent width (and therefore in the
iron abundance) of AGN with cosmological redshift (Brusa, Gilli
& Comastri 2005; recently extended in the work by Chaudhary,
Brusa et al. 2010, 2012).
