A spectroscopic study of NGC 6251 and its companion galaxies
TL;DR: In this paper, the velocities of galaxies associated with the giant radio galaxy NGC 6251 confirm the presence of a poor cluster with a systemic redshift of z= 0.0244 +/- 0.0004 and a line-of-sight velocity dispersion of sigma{z}= 283 (+109, -52) km/s.
Modeling x-ray emission of a straight jet : PKS 0920-397
D. A. Schwartz,Francesco Massaro,A. Siemiginowska,Diana M Worrall,Mark Birkinshaw,H. L. Marshall,Daniel A. Evans,Eric S. Perlman,Jonathan Gelbord,James E. J. Lovell,Leith Godfrey,Geoffrey V. Bicknell,R. Ojha,Martin J. Hardcastle,Sebastian Jester,Svetlana G. Jorstad,Lukasz Stawarz +16 more
TL;DR: In this article, the authors investigate the hypothesis that the jet X-ray emission is due to inverse-Compton (IC) scattering on the cosmic microwave background (CMB) from the same population of relativistic electrons that give rise to the radio emission.

P. Bonfini,Andreas Zezas,Mark Birkinshaw,Diana M Worrall,G. Fabbiano,Ewan O'Sullivan,Ginevra Trinchieri,Anna Wolter +7 more
TL;DR: In this paper, an analysis of the Globular Cluster (GC) population of the elliptical galaxy NGC 4261 based on HST WFPC2 data in the B, V and I bands is presented.

Unmasking the active galactic nucleus in pks j2310-437
TL;DR: In this article, the authors present new observations aimed at refining the measurement of the source's properties, and conclude that the most likely explanation for the bright central X-ray emission is synchrotron radiation from high-energy electrons.

TL;DR: In this paper, the authors proposed a method to solve the UHRA problem in the context of protein-protein interactions, which is not available in the UHARA database.
