Blazars as Ultra-High-Energy Cosmic-Ray Sources: Implications for TeV Gamma-Ray Observations
Ultra-High-Energy Cosmic-Ray Sources Implications TeV Gamma-Ray Observations
2011/10/20
Spectral fitting of correlated multiwavelength data of BL Lac objects and Fanaroff-Riley I radio galaxies gives the mean comoving magnetic field strength B', the bulk outflow Doppler factor Gamma, and...
X-ray Observations of Radio Transients without Optical Hosts
X-ray Observations Radio Transients without Optical Hosts
2011/10/19
We present a 50 ks Chandra ACIS-I X-ray observation of the Bower et al. VLA archival field. The observations reach a limiting sensitivity of ~1E-4 counts/s, corresponding to a flux of a few times 1E-1...
Constraints on the Cosmic-Ray Density Gradient beyond the Solar Circle from Fermi gamma-ray Observations of the Third Galactic Quadrant
cosmic rays – gamma rays ISM – ISM general
2010/11/10
We report an analysis of the interstellar-ray emission in the third Galactic quadrant measured
by the Fermi Large Area Telescope. The window encompassing the Galactic plane from longitude 210◦ ...
Cosmic Ray e^+/(e^- + e^+) and pbar/p Ratios Explained by an Injection Model Based on Gamma-ray Observations
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/6
We present a model of cosmic ray injection into the Galactic space based on recent gamma-ray observations of supernova remnants (SNRs) and pulsar wind nebulae (PWNe) by the Fermi Large Area Telescope ...
X-ray observations of sub-mm LABOCA galaxies in the eCDFS
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/7
We explore the X-ray properties of the 126 sub-mm galaxies (SMGs) of the LABOCA survey in the CDFS and the eCDFS regions. SMGs are believed to experience massive episodes of star-formation. Our goal i...
Radio and X-ray observations of Five TeV SNRs
High Energy Astrophysical Phenomena (astro-ph.HE) Galaxy Astrophysics (astro-ph.GA)
2010/12/23
We briefly summarize recent results of five TeV SNRs from radio and X-ray observations. We focus on remeasuring kinematic distances of 5 TeV SNRs, i.e. HESS J1732-347/SNR G353.6-0.7 (3.2 kpc), HESS J1...
