NLTE Model Atmosphere Analysis of the LMC Supersoft X-ray Source CAL 83

Kavli Affiliate: Andrew P. Rasmussen | First 5 Authors: Thierry Lanz, Gisela A. Telis, Marc Audard, Frits Paerels, Andrew P. Rasmussen | Summary: We present a non-LTE model atmosphere analysis of Chandra HRC-S/LETG and XMM-Newton RGS spectroscopy of the prototypical supersoft source CAL 83 in the Large Magellanic Cloud. Taken with a 16-month interval, the […]

Measurements of Sunyaev-Zel’dovich Effect Scaling Relations for Clusters of Galaxies

Kavli Affiliate: Bradford Benson | First 5 Authors: B. A. Benson, P. A. R. Ade, J. J. Bock, K. M. Ganga, C. N. Henson | Summary: We present new measurements of the Sunyaev-Zel’dovich (SZ) effect from clusters of galaxies using the Sunyaev-Zel’dovich Infrared Experiment (SuZIE II). We combine these new measurements with previous cluster observations […]

Chandra Observations and Monte Carlo Simulations of the Grain-Scattered Halo of the Binary X-Ray Pulsar 4U 1538-52

Kavli Affiliate: George W. Clark | First 5 Authors: George W. Clark, , , , | Summary: Properties of the X-ray halo of the eclipsing X-ray pulsar 4U 1538-52 are derived from a 25 ksec observation by the Chandra X-Ray Observatory. Profiles of the halo, compiled in two energy ranges, 2 to 4 keV and […]

Possible Evidence For Axino Dark Matter In The Galactic Bulge

Kavli Affiliate: Liantao Wang | First 5 Authors: Dan Hooper, Lian-Tao Wang, , , | Summary: Recently, the SPI spectrometer on the INTEGRAL satellite observed strong 511 keV line emission from the galactic bulge. Although the angular distribution (spherically symmetric with width of sim 9 degree) of this emission is difficult to account for with […]
