The Sloan Digital Sky Survey-II Supernova Survey: Technical Summary
Joshua A. Frieman, B. Bassett, A. Becker +98
The Sloan Digital Sky Survey-II (SDSS-II) has embarked on a multi-year project to identify and measure light curves for intermediate-redshift (0.05 < z < 0.35) Type Ia supernovae (…
Two Types of X-ray Spectra in Cataclysmic Variables
K. Mukai, A. Kinkhabwala, J. R. Peterson +2
We present Chandra HETG spectra of seven cataclysmic variables. We find that they divide unambiguously into two distinct types. Spectra of the first type are remarkably well fit by…
High Resolution X-Ray Spectroscopic Constraints on Cooling Flow Models of Clusters of Galaxies and Gaseous Haloes Around Elliptical Galaxies
S. M. Kahn, J. R. Peterson, F. B. S. Paerels +6
In many clusters of galaxies, the cooling time at the core of the intracluster medium is much less than the age of the system, suggesting that the the gas should continually lose e…
Soft X-ray emission lines from a relativistic accretion disk in MCG -6-30-15 and Mrk 766
G. Branduardi-Raymont, M. Sako, S. M. Kahn +3
XMM-Newton Reflection Grating Spectrometer (RGS) spectra of the Narrow Line Seyfert 1 galaxies MCG -6-30-15 and Mrk 766 are physically and spectroscopically inconsistent with stand…
