Spectral and Timing Studies of Cyg X-1 in the Low/Hard State with Suzaku
black hole physics — accretion — stars: individual (Cygnus X-1)—X- ray:binaries
2011/10/11
From 2005 to 2009, 25 observations of Cyg X-1 were performed with Suzaku, achieving a total exposure of 446 ks. In all observations, the source was found in the low/hard state, while the 1.5--12.0 keV...
Discovery and follow-up studies of the extended, off-plane, VHE gamma-ray source HESS J1507-622
follow-up studies off-plane VHE gamma-ray source HESS J1507-622
2011/1/10
Context: The detection of gamma-rays in the very-high-energy (VHE) range (100 GeV-100 TeV) offers the possibility of studying the parent population of ultrarelativistic particles found in astrophysica...
Studies of Diffuse Interstellar Bands. V. Pairwise Correlations of Eight Strong DIBs and Neutral Hydrogen, Molecular Hydrogen, and Color Excess
ISM lines and bands − ISM molecules
2010/11/15
We establish correlations between equivalent widths of eight diffuse interstel-lar bands (DIBs), and examine their correlations with atomic hydrogen, molec-ular hydrogen, and EB−V . The DIBs are...

Acoustic transient event reconstruction and sensitivity studies with the South Pole Acoustic Test Setup
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/5
The South Pole Acoustic Test Setup (SPATS) consists of four strings instrumented with seven acoustic sensors and transmitters each, which are deployed in the upper 500 m of the IceCube holes.
Longitudinal EAS-Development Studies in the Air-Shower Experiment KASCADE-Grande
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/4
A large area (128 m^2) Muon Tracking Detector (MTD), located within the KASCADE experiment, has been built with the aim to identify muons (E_mu > 0.8 GeV) and their directions in extensive air showers...
Hubble Space Telescope Studies of Nearby Type Ia Supernovae: The Mean Maximum Light Ultraviolet Spectrum and its Dispersion
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present the first results of an ongoing campaign using the STIS spectrograph on-board the Hubble Space Telescope (HST) whose primary goal is the study of near ultraviolet (UV) spectra of local Type...
