TL;DR: In this paper, an X-ray jet with Chandra imaging of the z = 1.187 radio-loud quasar PKS 1127-145 was discovered, which contains 273 ± 5 net counts in 27 ks and extends ~30'' from the quasar core.

Aneta Siemiginowska,Jill Bechtold,Thomas L. Aldcroft,Martin Elvis,D. E. Harris,Adam Dobrzycki +5 more
TL;DR: In this article, an X-ray jet with Chandra imaging of the z=1.187 radio-loud quasar PKS1127-145 was discovered, which contains 273+/-5 net counts in 27ksec and extends ~30 arcsec, from the quasar core.
Journal ArticleDOI
X-Ray Properties of the Gigahertz Peaked and Compact Steep Spectrum Sources
Aneta Siemiginowska,Stephanie M. LaMassa,Stephanie M. LaMassa,Thomas L. Aldcroft,Jill Bechtold,Martin Elvis +5 more
TL;DR: In this paper, the authors present Chandra X-ray Observatory observations of GNSS and compact steep spectrum (CSS) radio sources, including 13 quasars and 3 galaxies, with measured 2-10 keV x-ray luminosities within 1042-1046 erg s−1.
Journal ArticleDOI
Sdss j1254+0846: a binary quasar caught in the act of merging
Paul J. Green,Paul J. Green,Adam D. Myers,Adam D. Myers,Wayne A. Barkhouse,Wayne A. Barkhouse,John S. Mulchaey,Vardha N. Bennert,Thomas J. Cox,Thomas J. Cox,Thomas L. Aldcroft +10 more
TL;DR: In this article, the first luminous, spatially resolved binary quasar that clearly inhabits an ongoing galaxy merger was presented, and the triggering of two quasars during a merger had only been hypothesized but their observations provided strong evidence of such an event.
