X-ray monitoring of optical novae in M31 from July 2004 to February 2005
W. Pietsch, F. Haberl, G. Sala +9
Optical novae have recently been identified as the major class of supersoft X-ray sources in M31 based on ROSAT and early XMM-Newton and Chandra observations. This paper reports on…
The XMM-Newton wide-field survey in the COSMOS field. IV: X-ray spectral properties of Active Galactic Nuclei
V. Mainieri, G. Hasinger, N. Cappelluti +25
We present a detailed spectral analysis of point-like X-ray sources in the XMM-COSMOS field. Our sample of 135 sources only includes those that have more than 100 net counts in the…
The Evolution of Galaxy Dust Properties for 1<z<2.5
Stefan Noll, Daniele Pierini, Maurilio Pannella +1
Fundamental properties of the extinction curve, like the slope in the rest-frame UV and the presence/absence of a broad absorption excess centred at 2175A (the UV bump), are invest…
The X-ray Properties of Early-Type Galaxies in the Extended Chandra Deep Field-South
B. D. Lehmer, W. N. Brandt, D. M. Alexander +8
We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Fiel…
A Survey for Supernovae in Massive High-Redshift Clusters
Keren Sharon, A. Gal-Yam, D. Maoz +12
We describe our ongoing program designed to measure the SN-Ia rate in a sample of massive z=0.5-0.9 galaxy clusters. The SN-Ia rate is a poorly known observable, especially at high…
Revealing the Nature of Algol Disks through Optical and UV Spectroscopy, Synthetic Spectra, and Tomography of TT Hydrae
Brendan Miller, Jan Budaj, Mercedes Richards +2
We have developed a systematic procedure to study the disks in Algol-type binaries using spectroscopic analysis, synthetic spectra, and tomography. We analyzed 119 H-alpha spectra…
