The Lack of Diffuse, Non-thermal Hard X-ray Emission in the Coma Cluster: The Swift Burst Alert Telescope's Eye View
Daniel R. Wik,Craig L. Sarazin,Alexis Finoguenov,W. H. Baumgartner,Richard F. Mushotzky,Takashi Okajima,Jack Tueller,Tracy E. Clarke +7 more
TL;DR: In this paper, Renaud et al. used reconstructed sky images from the 58-month Swift Burst Alert Telescope (BAT) all-sky survey to test and implement a method for extracting the fluxes of extended sources, assuming specified spatial distributions.
Journal ArticleDOI

TL;DR: In this article, the authors analyzed NuSTAR/Chandra/XMM-Newton observations from a sample of 12 galaxies within 5 Mpc (megaparsecs) having stellar masses (M (sub asterisk)) 10 (sup 7-11) solar masses and star formation rates (SFRs) approximately 0.01-15 solar masses per year.

Ruta Kale,Daniel R. Wik,Daniel R. Wik,Daniel R. Wik,Simona Giacintucci,Tiziana Venturi,G. Brunetti,Rossella Cassano,Daniele Dallacasa,Daniele Dallacasa,F. de Gasperin +10 more
TL;DR: In this paper, the authors reported the discovery of a single radio relic in the galaxy cluster PLCK G200.9-28.2 using the giant metrewave radio telescope at 235 and 610 MHz and the Karl G. Jansky Very Large Array at 1500 MHz.
