Welcome to Mari Polletta web site !

I am a researcher at the Istituto di Astrofisica Spaziale e Fisica Cosmica (IASF). The IASF is part of the National Institute for Astrophysics (INAF)..

I am a member of the Spitzer Wide-Area Infrared Extragalactic Survey (SWIRE) Team and a huge fan of Active Galactic Nuclei (AGN), especially of the heavily obscured and extremely luminous ones. The figure on the left shows the current record-holder as the most luminous obscured AGN in the 50 square degrees covered by SWIRE (aka SW104409).

My research activities focus on understanding the role of AGN in regulating galaxy evolution, and the physical processes responsible for their amazing properties. These goals require tracing, unveiling, and characterizing AGN at high redshifts (z=1-3), when both star-formation and accretion activities peaked. You can learn more on AGN here.

My research is based on the exploitation of data from multi-wavelength surveys of various areas and depths. Check out below the facilities that provide some of the data I use for my research.
