The column density towards LMC X-1
Manfred Hanke, Joern Wilms, Michael A. Nowak +2
We measure the neutral absorption towards the black hole X-ray binary system LMC X-1 from six archival soft X-ray spectra obtained with the gratings and/or CCD detectors on Chandra…
Spatially Resolved Chandra HETG Spectroscopy of the NLR Ionization Cone in NGC 1068
Daniel A. Evans, Patrick M. Ogle, Herman L. Marshall +9
We present initial results from a new 440-ks Chandra HETG GTO observation of the canonical Seyfert 2 galaxy NGC 1068. The proximity of NGC 1068, together with Chandra's superb spat…
X-ray Emission and Corona of the Young Intermediate Mass Binary Ori E
David P. Huenemoerder, Norbert S. Schulz, Paola Testa +2
Theta 1 Ori E is a young, moderate mass binary system, a rarely observed case of spectral-type G-giants of about 3 Solar masses, which are still collapsing towards the main sequenc…
Searching for AGN Outflows: Spatially Resolved Chandra HETG Spectroscopy of the NLR Ionization Cone in NGC 1068
Daniel A. Evans, Patrick M. Ogle, Herman L. Marshall +9
We present initial results from a new 440-ks Chandra HETG GTO observation of the canonical Seyfert 2 galaxy NGC 1068. The proximity of NGC 1068, together with Chandra's superb spat…
The accretion disk corona and disk atmosphere of 4U 1624-490 as viewed by the Chandra-HETGS
Jingen Xiang, Julia C. Lee, Michael A. Nowak +2
We present a detailed spectral study (photoionization modelling and variability) of the "Big Dipper" 4U 1624-490 based on a \chandra-High Energy Transmission Gratings Spectrometer…
The Photoionized Accretion Disk in Her X-1
L. Ji, N. Schulz, M. Nowak +2
We present an analysis of several high-resolution Chandra grating observations of the X-ray binary pulsar Her X-1. With a total exposure of 170 ks, the observations are separated b…
