Research

I have led the new Chandra Legacy survey in the NOAO Boötes field, CDWFS. The CDWFS, with its deep multi-wavelength coverage and almost 6900 X-ray sources, is now the largest medium-depth survey conducted by the Chandra X-ray Observatory. The full paper and the public catalogs can be found at this link.

Machine-readable sensitivity curves and LogN-LogS

NuSTAR is a hard X-ray telescope. Thanks to its focusing optics and broadband coverage, it provided a factor of 100 improvement in sensitivity with respect to coded-mask hard X-ray telescopes.

As a member of the NuSTAR community, I studied the high-energy spectral and obscuration properties of local, heavily obscured (Compton-thick) AGNs. Although best performing with local, bright sources, NuSTAR has been extensively used to survey patches of the sky. In this context, I've led the NuSTAR Deep Survey of the UKIDSS-UDS field, which fits as the medium area-depth tier of the NuSTAR Extragalactic Surveys Program.
