The Rapidly Flaring Afterglow of the Very Bright and Energetic GRB 070125
Adria C. Updike, Joshua B. Haislip, Melissa C. Nysewander +52
We report on multi-wavelength observations, ranging from the X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the prese…
RHESSI Spectral Fits of Swift GRBs
Eric C. Bellm, Mark E. Bandstra, Steven E. Boggs +4
One of the challenges of the Swift era has been accurately determining Epeak for the prompt GRB emission. RHESSI, which is sensitive from 30 keV to 17 MeV, can extend spectral cove…
Observation of an unexpected hardening in the spectrum of GRB 021206
C. Wigger, O. Wigger, E. Bellm +1
GRB 021206 is one of the brightest GRBs ever observed. Its prompt emission, as measured by RHESSI, shows an unexpected spectral feature. The spectrum has a peak energy of about 700…
Observations of the Prompt Gamma-Ray Emission of GRB 070125
Eric C. Bellm, Kevin Hurley, Valentin Pal'shin +17
The long, bright gamma-ray burst GRB 070125 was localized by the Interplanetary Network. We present light curves of the prompt gamma-ray emission as observed by Konus-WIND, RHESSI,…
Origins of the 1/4 keV Soft X-Ray Background
Eric C. Bellm, John E. Vaillancourt
Snowden and coworkers have presented a model for the 1/4 keV soft X-ray diffuse background in which the observed flux is dominated by a ~ 10^6 K thermal plasma located in a 100-300…
Multipixel characterization of imaging CZT detectors for hard X-ray imaging and spectroscopy
S. V. Vadawale, J. Hong, J. Grindlay +8
We report our in-depth study of Cd-Zn-Te (CZT) crystals to determine an optimum pixel and guard band configuration for Hard X-ray imaging and spectroscopy. We tested 20x20x5mm crys…
