Shocks and sonic booms in the intracluster medium: X-ray shells and radio galaxy activity
C. S. Reynolds, S. Heinz, M. C. Begelman
Motivated by hydrodynamic simulations, we discuss the X-ray appearance of radio galaxies embedded in the intracluster medium (ICM) of a galaxy cluster. We distinguish three regimes…
ASCA Observation of an X-Ray-Luminous Active Nucleus in Markarian 231
Philip R. Maloney, Christopher S. Reynolds
We have obtained a moderately long (100 kilosecond) ASCA observation of the Seyfert 1 galaxy Markarian 231, the most luminous of the local ultraluminous infrared galaxy (ULIRG) pop…
Observations of the core of the Pleiades with the Chandra X-ray Observatory
Anita Krishnamurthi, Christopher S. Reynolds, Jeffrey L. Linsky +2
We present results from a 36-ksec observation of the core of the Pleiades open cluster using ACIS-I on the Chandra X-ray Observatory. We have detected 57 sources, most of which do…
Intermittent radio galaxies and source statistics
C. S. Reynolds, M. C. Begelman
We suggest that extragalactic radio sources are intermittent on timescales of 10^4-10^5 yr. Using a simple spherical model of a cocoon/shock system, it is found that inactive sourc…
The profile and equivalent width of the X-ray iron emission-line from a disk around a Kerr black hole
Y. Dabrowski, A. C. Fabian, K. Iwasawa +2
Recent X-ray observations have shown broad, skewed iron line emission from Seyfert 1 galaxies which is explained by the emission being fluorescence on a disk close to a black hole.…
