Evolution of a Powerful Radio Loud Quasar 3C186 and its Impact on the Cluster Environment at z=1
Aneta Siemiginowska, Thomas L. Aldcroft, Doug Burke +4
X-ray cluster emission has been observed mainly in clusters with "inactive" cD galaxies (L_bol ~1E40-1E43erg/sec), which do not show signs of accretion onto a SMBH. Our recent Chan…

The 300 kpc Long X-ray Jet in PKS 1127-145, z=1.18 Quasar: Constraining X-ray Emission Models
Aneta Siemiginowska, Lukasz Stawarz, C. C. Cheung +4
We present a ~100 ksec Chandra X-ray observation and new VLA radio data of the large scale, 300 kpc long X-ray jet in PKS1127-145, a radio loud quasar at redshift z=1.18. With this…
