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…
Multiwavelength Analysis of Fermi-LAT Blazars with High-Significance Periodicity: Detection of a Long-Term Rising Emission in PG 1553+113
P. Peñil, J. R. Westernacher-Schneider, M. Ajello +6
Blazars display variable emission across the entire electromagnetic spectrum, with timescales that can range from a few minutes to several years. Our recent work has shown that a s…
A multi-epoch X-ray study of the nearby Seyfert 2 galaxy NGC 7479: Linking column density variability to the torus geometry
Andrealuna Pizzetti, Nuria Torres-Alba, Stefano Marchesi +3
Active galactic nuclei (AGN) are powered by accreting supermassive black holes, surrounded by a torus of obscuring material. Recent studies have shown how the torus structure, form…
Chandra Follow-up Observations of Swift-BAT-selected AGNs II
Ross Silver, Nuria Torres-Alba, Xiurui Zhao +7
We present the combined Chandra and Swift-BAT spectral analysis of nine low-redshift (z <= 0.10), candidate heavily obscured active galactic nuclei (AGN) selected from the Swift-BA…
Compton-Thick AGN in the NuSTAR era VII. A joint NuSTAR, Chandra and XMM-Newton analysis of two nearby, heavily obscured sources
Alberto Traina, Stefano Marchesi, Cristian Vignali +11
We present the joint Chandra, XMM-Newton and NuSTAR analysis of two nearby Seyfert galaxies, NGC 3081 and ESO 565-G019. These are the only two having Chandra data in a larger sampl…
Multi-messenger observations of a flaring blazar coincident with high-energy neutrino IceCube-170922A
The IceCube, Fermi-LAT, MAGIC +13
Individual astrophysical sources previously detected in neutrinos are limited to the Sun and the supernova 1987A, whereas the origins of the diffuse flux of high-energy cosmic neut…
