Toward measuring the spin of obscured supermassive black holes: a critical assessment with disk megamasers
Alberto Masini, Annalisa Celotti, Samuele Campitiello
Mass and spin are two fundamental properties of astrophysical black holes. While some established, indirect methods are adopted to measure both these properties of active galactic…
The NuSTAR Extragalactic Survey of the James Webb Space Telescope North Ecliptic Pole Time-Domain Field
X. Zhao, F. Civano, F. M. Fornasini +17
We present the extragalactic survey of the () North Ecliptic Pole (NEP) Time-Domain Field. The survey covers a 0.16 deg…
Chandra Observations of Excess Fe K Line Emission in Galaxies with High Star Formation Rates: X-ray Reflection on Galaxy Scales?
Wei Yan, Ryan C. Hickox, Chien-Ting J. Chen +4
In active galactic nuclei (AGN), fluorescent Fe K (iron) line emission is generally interpreted as originating from obscuring material around a supermassive black hole (SMBH) on…
A new distant Giant Radio Galaxy in the Boötes field serendipitously detected by Chandra
Alberto Masini, Annalisa Celotti, Paola Grandi +2
Giant Radio Galaxies (GRGs) are the largest single structures in the Universe. Exhibiting extended radio morphology, their projected sizes range from 0.7 Mpc up to 4.9 Mpc. LOFAR h…
