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...
Constraints on a hadronic model for unidentified off-plane galactic gamma-ray sources
hadronic model unidentified off-plane galactic gamma-ray sources
2011/1/10
Recently the H.E.S.S. collaboration announced the detection of an unidentified gamma-ray source with an off-set from the galactic plane of 3.5 degrees: HESS J1507-622. If the distance of the object is...
Compact radio emission in Ultra Luminous X-ray sources
Galaxies general – X-rays general – ISM HII regions
2010/11/10
We present results from our studies of radio emission from selectecd Ultra Luminous X-ray (ULX) sources, using archival Giant Metrewave Radio Telescope (GMRT) data and new European VLBI Network (EVN) ...
The scaling of X-ray variability with luminosity in Ultra-luminous X-ray sources
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2011/1/5
We investigated the relationship between the X-ray variability amplitude and X-ray luminosity for a sample of 14 bright Ultra-luminous X-ray sources (ULXs) with XMM-Newton/EPIC data, and compare it wi...
