X-ray emitting AGN unveiled by the Chandra Multiwavelength Project

John D. Silverman, Paul J. Green, Thomas L. Aldcroft +4

We present an X-ray and optical analysis of a 2-8 keV flux limited (fx > 10e-14 erg s^-1 cm^-2) sample of 126 AGN detected in 16 Chandra fields. This work represents a small though…

An X-ray jet discovered by Chandra in the z=4.3 radio-selected quasar GB 1508+5714

Aneta Siemiginowska, Randall K. Smith, Thomas L. Aldcroft +3

We report the Chandra discovery of an X-ray jet associated with the redshift 4.3 radio-loud quasar GB 1508+5714. The jet X-ray emission peaks ~2 arcsec to the South-West of the qua…

Chandra Observation of 3C 212: a New Look at the X-ray and UV Absorbers

T. L. Aldcroft, A. Siemiginowska, M. Elvis +3

The red quasar 3C 212 (z=1.049) is one of the most distant and most luminous AGN which has shown evidence of an X-ray warm absorber. In order to further investigate this unusual qu…

X-ray emission from GPS/CSS sources

Aneta Siemiginowska, Thomas L. Aldcroft, Jill Bechtold +3

The high spatial resolution of the Chandra X-ray Observatory allows us to study the environment of GPS/CSS sources to within an arcsec of the strong compact core. We present the di…

Chandra Discovery of an X-ray jet and Extended X-ray Structure in z=0.63 quasar, B2 0738+313

Aneta Siemiginowska, Carlo Stanghellini, Gianfranco Brunetti +8

We have made a 30 ksec Chandra observation of the redshift z=0.63 GPS quasar B2 0738+313. We detected X-ray emission from the core and have discovered a 200 kpc (projected on the s…

Lens or Binary? Chandra Observations of the Wide Separation Broad Absorption Line Quasar Pair UM425

T. L. Aldcroft, P. J. Green

We have obtained a 110 ksec Chandra ACIS-S exposure of UM425, a pair of QSOs at z=1.47 separated by 6.5 arcsec, which show remarkably similar emission and broad absorption line (BA…
