Main Research Fields

I am a researcher working on observational cosmology and extragalactic compact source science. My research is mostly focused on the analysis of data from experiments that observe the Cosmic Microwave Background (CMB). I am interested in the characterization of foreground emissions that contaminate the CMB, in particular the compact sources (radio and sub-mm sources, SZ clusters, etc.). I have developed several techniques based on linear filters and wavelets to detect and characterize Galactic and extragalactic objects that appear as compact sources in the CMB maps. These techniques have been successfully used to study the compact emission in WMAP, Planck, Herschel and QUIJOTE. I am also interested in the impact of polarized compact emission on the detectability of primordial B-modes produced by gravitational waves. Several CMB Polarization experiments like Planck, BICEP2, QUIJOTE or future COrE/PRISM-like and LiteBird satellites aim to detect, or to set limits, on the background of gravitational waves and the gravitational lensing-induced B-mode. I am PI of several proposals to follow up Planck sources with the Very Large Array.
