A Chandra Census of C2D YSOS: Evolution of X-ray Emission
Solar and Stellar Astrophysics (astro-ph.SR)
2010/12/24
We present an analytical study of a large sample of ~109 young stellar objects in the X-ray. Our objects were detected in X-ray independent of age. Unexpectedly, the X-ray energy is somewhat correlate...
An X-ray Selected Galaxy Cluster in the Lockman Hole at Redshift 1.753
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We have discovered an X-ray selected galaxy cluster with a spectroscopic redshift of 1.753. The redshift is of the brightest cluster galaxy (BCG), which is coincident with the peak of the X-ray surfac...
The XMM Cluster Survey: X-ray analysis methodology
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
The XMM Cluster Survey (XCS) is a serendipitous search for galaxy clusters using all publicly available data in the XMM- Newton Science Archive. Its main aims are to measure cosmological parameters an...
