Chandra Observations of the X-ray Point Source Population in NGC 4636
Jennifer Posson-Brown, Somak Raychaudhury, William Forman +2
We present the X-ray point source population in the nearby Virgo elliptical galaxy NGC 4636 from 3 Chandra/ACIS observations, totaling 193 ks, taken over 3 years. Using wavelet dec…
UBVRI Light Curves of 44 Type Ia Supernovae
Saurabh Jha, Robert P. Kirshner, Peter Challis +2
We present UBVRI photometry of 44 type-Ia supernovae (SN Ia) observed from 1997 to 2001 as part of a continuing monitoring campaign at the Fred Lawrence Whipple Observatory of the…
A Flux Limited Atlas of Galaxy Cluster Temperature Maps
R. Hank Donnelly, C. Jones, W. Forman +2
An atlas of gas temperature maps is presented for a flux limited catalog of galaxy clusters. The sample of clusters is based on the Edge et al. (1990) sample, with the inclusion of…
Mass-to-Light Ratios of Groups and Clusters of Galaxies
V. Hradecky, C. Jones, R. H. Donnelly +3
We constrain the mass-to-light ratios, gas mass fractions, baryon mass fractions and the ratios of total to luminous mass for a sample of eight nearby relaxed galaxy groups and clu…
Chandra Observation of Abell 2142: Survival of Dense Subcluster Cores in a Merger
M. Markevitch, T. J. Ponman, P. E. J. Nulsen +19
We use Chandra data to map the gas temperature in the central region of the merging cluster A2142. The cluster is markedly nonisothermal; it appears that the central cooling flow h…
Chandra X-Ray Detection of the Radio Hotspots of 3C295
D. E. Harris, P. E. J. Nulsen, T. P. Ponman +17
An observation of the radio galaxy 3C295 during the calibration phase of the Chandra X-ray Observatory reveals X-ray emission from the core of the galaxy, from each of the two prom…
