A bright thermonuclear X-ray burst simultaneously observed with Chandra and RXTE
J. J. M. in t Zand, D. K. Galloway, H. L. Marshall +6
The prototypical accretion-powered millisecond pulsar SAX J1808.4-3658 was observed simultaneously with Chandra-LETGS and RXTE-PCA near the peak of a transient outburst in November…
X-raying the Intergalactic OVI Absorbers
Y. Yao, T. M. Tripp, Q. D. Wang +5
The observed intergalactic OVI absorbers at z>0 have been regarded as a significant reservoir of the ``missing baryons''. However, to fully understand how these absorbers contribut…
High Resolution Gratings Spectroscopy of GRBs 030382 and 041006 with Chandra LETGS
N. R. Butler, G. R. Ricker, P. G. Ford +5
We present high resolution X-ray spectroscopy of two recent GRB afterglows observed with the Low Energy Transmission Gratings on Chandra. The afterglows to GRBs 030328 and 041006 a…
The X-ray Afterglows of GRB 020813 and GRB 021004 with Chandra HETGS: Possible Evidence for a Supernova Prior to GRB 020813
Nathaniel R. Butler, Herman L. Marshall, George R. Ricker +5
We report on the detection of an emission line near 1.3 keV, which we associate with blue-shifted hydrogen-like sulfur (S XVI), in a 76.8 ksec Chandra HETGS spectrum of the aftergl…
An Extreme Ultraviolet Explorer Atlas of Seyfert Galaxy Light Curves: Search for Periodicity
J. P. Halpern, K. M. Leighly, H. L. Marshall
The Deep Survey instrument on the Extreme Ultraviolet Explorer satellite (EUVE) obtained long, nearly continuous soft X-ray light curves of 5-33 days duration for 14 Seyfert galaxi…
Chandra Detection of X-ray Absorption from Local Warm/Hot Gas
T. Fang, C. Canizares, K. Sembach +3
Recently, with the Chandra X-ray Telescope we have detected several local X-ray absorption lines along lines-of-sight towards distant quasars. These absorption lines are produced b…
