A NuSTAR study of quasi-periodic oscillations from the ultraluminous X-ray sources in M82
Hamza El Byad, Matteo Bachetti, Silvia Columbu +13
The study of quasi-periodic oscillations in X-ray binaries provides valuable insights into the physics of accretion around compact objects. The M82 galaxy hosts two ultraluminous X…

The NuSTAR Local AGN Distribution Survey (NuLANDS) I: Towards a Truly Representative Column Density Distribution in the Local Universe
Peter G. Boorman, Poshak Gandhi, Johannes Buchner +33
Hard X-ray-selected samples of Active Galactic Nuclei (AGN) provide one of the cleanest views of supermassive black hole accretion, but are biased against objects obscured by Compt…
