Detecting Relativistic X-ray Jets in High-Redshift Quasars
Kathryn McKeough, Aneta Siemiginowska, C. C. Cheung +12
We analyze Chandra X-ray images of a sample of 11 quasars that are known to contain kiloparsec scale radio jets. The sample consists of five high-redshift (z >= 3.6) flat-spectrum…
X-ray properties of the Youngest Radio Sources and their Environments
Aneta Siemiginowska, Malgosia Sobolewska, Giulia Migliori +4
We present the results of the first X-ray study of a sample of 16 young radio sources classified as Compact Symmetric Objects (CSOs). We observed six of them for the first time in…
First detection in gamma-rays of a young radio galaxy: Fermi-LAT observations of the Compact Symmetric Object PKS 1718-649
Giulia Migliori, Aneta Siemiginowska, Malgorzata Sobolewska +4
We report the -ray detection of a young radio galaxy, PKS 1718649, belonging to the class of Compact Symmetric Objects (CSOs), with the Large Area Telescope (LAT) on board th…
Bayesian Estimates of Astronomical Time Delays between Gravitationally Lensed Stochastic Light Curves
Hyungsuk Tak, Kaisey Mandel, David A. van Dyk +3
The gravitational field of a galaxy can act as a lens and deflect the light emitted by a more distant object such as a quasar. Strong gravitational lensing causes multiple images o…
