An X-ray Galaxy Cluster Survey for Investigations of Dark Energy

Z. Haiman, S. Allen, N. Bahcall +34

The amount and nature of dark energy (DE) can be tightly constrained by measuring the spatial correlation features and evolution of a sample of ~ 100,000 galaxy clusters over the r…

Stellar Coronal Spectroscopy with the Chandra HETGS

David P. Huenemoerder, Bram Boroson, Norbert S. Schulz +4

Spectroscopy with the Chandra High Energy Transmission Grating Spectrometer provides details on X-ray emission and activity from young and cool stars through resolution of emission…

Highly Ionized Absorption in the X-ray Spectrum of Cyg X-1

H. L. Marshall, N. S. Schulz, T. Fang +4

Using the Chandra High Energy Transmission Grating Spectrometer (HETGS), we have found significant absorption features in the X-ray spectrum of Cyg X-1 taken in the continuous cloc…

The Chandra High Energy Transmission Grating Spectrometer probes the dusty warm absorber in the Seyfert 1 galaxy MCG--6-30-15

J. C. Lee, C. R. Canizares, H. L. Marshall +4

The Chandra HETGS spectra of the Seyfert 1 galaxy MCG--6-30-15 show numerous narrow, unresolved (FWHM < 200 km/s) absorption lines from a wide range of ionization states of N, O, M…

X-ray Spectra and Light Curves of AR Lac: Temperature Structure, Abundances, and Variability

David Huenemoerder, Claude Canizares, Kevin Tibbetts

We observed AR Lac, an eclipsing RS CVn binary star, with the Chandra High Energy Grating Spectrometer for a total of 100 ks divided into six intervals covering both quadratures an…

Chandra Observations of a Cluster and Two Quasars at High Redshift

C. R. Canizares, T. E. Jeltema, T. Fang +6

We observed MS 1054-0321, the highest redshift cluster of galaxies in the Einstein Medium Sensitivity Survey (EMSS), with the Chandra ACIS-S detector. We find the X-ray temperature…
