New Gamma-Ray Probe of the Baryonic Dark Matter
A. F. Iyudin, V. Burwitz, J. Greiner +2
We expand on the recently reported detections of the gamma-ray resonant absorption along the line of sight toward gamma-ray bright quasars (QSOs), like 3C279. We propose to use thi…
Measurements of Gamma-Ray Bursts (GRBs) with Glast
G. G. Lichti, M. Briggs, R. Diehl +9
One of the scientific goals of the main instrument of GLAST is the study of Gamma-Ray Bursts (GRBs) in the energy range from ~20 MeV to ~300 GeV. In order to extend the energy meas…
Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB 030329
J. Greiner, S. Klose, K. Reinsch +23
We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. We establish the polarization light curve, detect susta…
The optical/near-IR spectral energy distribution of the GRB 000210 host galaxy
J. Gorosabel, L. Christensen, J. Hjorth +25
We report on UBVRIZJsHKs-band photometry of the dark GRB 000210 host galaxy. Fitting a grid of spectral templates to its Spectral Energy Distribution (SED), we derived a photometri…
Comptonization, the X-ray-radio correlation and the long-term periodicity in the chi-states of GRS 1915+105
Arne Rau, Jochen Greiner
We analyzed 139 chi-state observations of GRS 1915+105 with RXTE from 1997 to 2000 and found i) that the observations fall into two groups with different Comptonization behavior, i…
K band monitoring of GRS 1915+105 during 1999/2000
J. Greiner, F. J. Vrba, A. A. Henden +2
We report on long-term K band photometry of the galactic microquasar GRS 1915+105 since March 1999. We see variations of more than 1 mag, which are seemingly correlated with variat…
