Chemical enrichment of the complex hot ISM of the Antennae galaxies: I. Spatial and spectral analysis of the diffuse X-ray emission
A. Baldi, J. C. Raymond, G. Fabbiano +5
We present an analysis of the properties of the hot interstellar medium (ISM) in the merging pair of galaxies known as The Antennae (NGC 4038/39), performed using the deep, coadded…
The Time-Variable Ultra-Luminous X-ray Sources of "The Antennae"
G. Fabbiano, A. Zezas, A. R. King +3
We report the first results of the Chandra temporal monitoring of the ultra-luminous X-ray sources (ULXs) in the Antennae galaxies (NGC 4038/39). Observations at four different epo…
The X-ray Source Population of "The Antennae" Galaxies: X-ray Properties from Chandra and Multiwavelength Associations
A. Zezas, G. Fabbiano, A. H. Rots +1
[abridged] We investigate the nature of the luminous X-ray source population detected in a (72 ks) Chandra ACIS-S observation of NGC 4038/39, the Antennae galaxies. We derive the a…
Chandra Observations of the Young Pulsar PSR B0540-69
P. Kaaret, H. L. Marshall, T. L. Aldcroft +6
The young pulsar PSR B0540-69 was one of the first targets observed with the Chandra X-Ray Observatory. The high angular resolution of Chandra allows us to resolve the compact nebu…
RXTE Absolute Timing Results for the Pulsars B1821-24 and B1509-58
A. H. Rots, K. Jahoda, D. J. Macomb +9
Observations with the Rossi X-ray Timing Explorer and the Jodrell Bank, Parkes, and Green Bank telescopes have enabled us to determine the time delay between radio and X-ray pulses…
