Identification of gamma-ray emission from 3C345 and NRAO512
Galaxies: active - quasars: individual (3C 345, NRAO512, B3 1640+396) - Gamma rays: galaxies
2011/10/9
For more than 15 years, since the days of the Energetic Gamma-Ray Experiment Telescope (EGRET) on board the Compton Gamma-Ray Observatory (CGRO; 1991-2000), it has remained an open question why the pr...
X-ray flare candidates in short gamma-ray bursts
gamma-ray: bursts – radiation mechanism: non-thermal –X-rays
2011/9/30
We present the first systematic study of X-ray flare candidates in short gamma-ray bursts (SGRBs) exploiting the large 6-year Swift database with the aim to constrain the physical nature of such fluct...
Fermi Large Area Telescope Observations of the Active Galaxy 4C +55.17: Steady, Hard Gamma-Ray Emission and its Implications
Steady Hard Gamma-Ray Emission Implications
2011/9/29
We report Fermi/LAT observations and broad-band spectral modeling of the radio-loud active galaxy 4C +55.17 (z=0.896), formally classified as a flat-spectrum radio quasar. Using 19 months of all-sky s...

An Exact Solution of the Gamma Ray Burst Arrival Time Analysis Problem
Gamma Ray Bursts triangulation
2009/5/19
An analytical solution of the GRB arrival time analysis is
presented. The errors in the position of the GRB resulting from timing and
position errors of different satellites are calculated. A simple...
This talk focuses on the various aspects we learnt from multiband
observations of GRBs both, before and during the afterglow era.
A statistical analysis to estimate the probable redshifts of host ga...

X-rays—supernova remnants interstellar medium shocks—Tycho’s SNR—SN 1572
2009/5/19
We present a new Chandra observation of Tycho’s supernova
remnant with the Advanced CCD Imaging Spectrometer. Multicolor Xray
imaging reveals new details of the outer shock and ejecta. At energies
