TL;DR: In this article, the authors reported broadband X-ray observations of the nuclear region of the galaxy M82 that reveal pulsations with an average period of 1.37 seconds and a 2.5-day sinusoidal modulation.

TL;DR: The ROSAT Brightest Cluster Sample (BCS) as mentioned in this paper is the largest X-ray selected cluster sample compiled to date, containing Abell clusters, Zwicky clusters and other clusters selected from their Xray properties alone.

TL;DR: In this article, the authors present new spectra of dominant galaxies in X-ray selected clusters, which combine with their previously published spectra to form a sample of 256 dominant galaxies.

TL;DR: In this paper, the authors employ contemporaneous optical, ultraviolet (UV) and X-ray observations from the XMM-Newton European Photon Imaging Camera (EPIC-pn) and Optical Monitor (OM) archives to present, for the first time, simultaneous spectral energy distributions (SEDs) for the majority of the Peterson et al. reverberation mapped sample of active galactic nuclei (AGN).

TL;DR: In this article, the authors presented a low-flux extension of the X-ray-selected ROSAT Brightest Cluster Sample (BCS) published in Paper I of this series and employed an identical selection procedure, the BCS extension is compiled from ROSAT All-Sky Survey (RASS) data in the northern hemisphere (δ≥0°) and at high Galactic latitudes (|b|≥20°).
