We identify sources with extremely hard X-ray spectra (i.e., with photon indices of ${\rm{\Gamma }}\lesssim 0.6$) in the 13 deg2 NuSTAR serendipitous survey, to search for the most highly obscured active galactic nuclei (AGNs) detected at $\gt 10\,\m...

NGC 1448 is one of the nearest luminous galaxies (L8−1000μm> 109L⊙) to ours (z = 0.00390), and yet the active galactic nucleus (AGN) it hosts was only recently discovered, in 2009. In this paper, we present an analysis of the nuclear source across th... Read More about A New Compton-thick AGN in our Cosmic Backyard: Unveiling the Buried Nucleus in NGC 1448 with NuSTAR.

The NuSTAR Serendipitous Survey: The 40-month Catalog and the Properties of the Distant High-Energy X-ray Source Population (2017)
Journal Article

Astrophysical Journal, 836(1), Article 99. https://doi.org/10.3847/1538-4357/836/1/99

We present the first full catalog and science results for the NuSTAR serendipitous survey. The catalog incorporates data taken during the first 40 months of NuSTAR operation, which provide ~20Ms of effective exposure time over 331 fields, with an are...
