An X-ray Significantly Variable, Luminous, Type 2 Quasar at z = 2.99 with a Massive Host Galaxy
Xiurui Zhao, Stefano Marchesi, Marco Ajello +8
We present a comprehensive X-ray analysis and spectral energy distribution (SED) fitting of WISEA J171419.96+602724.6, an extremely luminous type 2 quasar at = 2.99. The source…
Stripe 82-XL: the 54.8 deg and 18.8 Ms Chandra and XMM-Newton point source catalog and number of counts
Alessandro Peca, Nico Cappelluti, Stephanie LaMassa +9
We present an enhanced version of the publicly-available Stripe 82X catalog (S82-XL), featuring a comprehensive set of 22,737 unique X-ray point sources identified with a significa…
Hydrogen Column Density Variability in a Sample of Local Compton-Thin AGN II
A. Pizzetti, N. Torres-Alba, S. Marchesi +7
We present the multi-epoch analysis of 13 variable, nearby (z<0.1), Compton-thin (22<logN_H<24) active galactic nuclei (AGN) selected from the 105-month BAT catalog. Analyzing all…
Multiwavelength Variability Analysis of Fermi-LAT Blazars
P. Peñil, J. Otero-Santos, M. Ajello +6
Blazars present highly variable -ray emission. This variability, which can range from a few minutes to several years, is also observed at other wavelengths across the entire ele…
The High Energy X-ray Probe (HEX-P): Bringing the Cosmic X-ray Background into Focus
Francesca Civano, Xiurui Zhao, Peter Boorman +29
Since the discovery of the cosmic X-ray background (CXB), astronomers have strived to understand the accreting supermassive black holes (SMBHs) contributing to its peak in the 10-4…
The High Energy X-ray Probe (HEX-P): The Future of Hard X-ray Dual AGN Science
Ryan W. Pfeifle, Peter G. Boorman, Kimberly A. Weaver +15
A fundamental goal of modern-day astrophysics is to understand the connection between supermassive black hole (SMBH) growth and galaxy evolution. Merging galaxies offer one of the…
