Different types of ultraluminous X-ray sources in NGC 4631
Roberto Soria, Kajal Ghosh
We have re-examined the most luminous X-ray sources in the starburst galaxy NGC 4631, using XMM-Newton, Chandra and ROSAT data. The most interesting source is a highly variable sup…
Multiwavelength study of the bright X-ray source population in the interacting galaxies NGC5774/NGC5775
Kajal K. Ghosh, Douglas A. Swartz, Allyn F. Tennant +5
A few nearby interacting galaxies are known that host elevated number of ultraluminous X-ray sources. Here we report the results of a multiwavelength study of the X-ray source popu…
A QSO plus host system lensed into a 6" Einstein ring by a low redshift galaxy
Kajal K Ghosh, D. Narasimha
We report the serendipitous discovery of an "Einstein Ring" in the optical band from the Sloan Digital Sky Survey (SDSS) data and associated four images of a background source. The…
Chandra X-Ray Observatory Observations of the Globular Cluster M71
R. F. Elsner, C. O. Heinke, H. N. Cohn +12
We observed the nearby, low-density globular cluster M71 (NGC 6838) with the Chandra X-ray Observatory to study its faint X-ray populations. Five X-ray sources were found inside th…
UGC 7069: The largest ring galaxy
Kajal K. Ghosh, Michela Mapelli
We find that UGC 7069 is the largest ring galaxy known to date. In this Letter, we present a multiwavelength study of this galaxy (combining radio, 2MASS, optical and ultraviolet d…
Detection of X-ray elongated emission from a ultraluminous X-ray source in the interacting pair of galaxies NGC 5953/5954
Margarita Rosado, Kajal K. Ghosh, Isaura Fuentes-Carrera
We present radio through X-ray results of a bright (10^{40} erg/s in the 0.5 to 8.0 keV band) ultraluminous X-ray source (ULX), CXOU J153434.9+151149, in the starburst, interacting…
