A Mid-Infrared Study of the Young Stellar Population in the NGC 2024 Cluster
Karl E. Haisch, Elizabeth A. Lada, Robert K. Pina +2
We present the results of the first broadband 10.8 um survey of the NGC 2024 cluster. The mid-infrared data were combined with our previously published JHKL photometry in order to…
Chandra Observations of M31
M. R. Garcia, S. S. Murray, F. A. Primini +3
As part of the Chandra GTO program we are monitoring and surveying M31 using the HRC and ACIS cameras. These observations have resolved the nuclear X-ray source into five separate…
Temperature Structure of Four Merging Clusters Obtained with Chandra
M. Markevitch, A. Vikhlinin, P. Mazzotta +1
We present preliminary Chandra results on z=0.2 clusters A665, A2163 and A2218, and a z=0.05 cluster A754. For A754, A665 and A2163, we have derived first high-resolution projected…
Surveys and the Blazar Parameter Space
E. S. Perlman, P. Padovani, H. Landt +5
The rareness of blazars, combined with the previous history of relatively shallow, single-band surveys, has dramatically colored our perception of these objects. Despite a quarter-…
Chandra Observations of M31 and their Implications for its ISM
F. Primini, M. Garcia, S. Murray +3
We have been regularly observing the bulge and inner disk of M31 for nearly 1 year, using both the HRC-I and ACIS-I instruments on the Chandra X-Ray Observatory. We present results…
The Chandra Multi-wavelength Project (ChaMP): a serendipitous survey with Chandra archival data
B. J. Wilkes, P. Green, R. Brissenden +34
The launch of the Chandra X-ray Observatory in July 1999 opened a new era in X-ray astronomy. Its unprecedented, <0.5" spatial resolution and low background are providing views of…
