Investigating Polarization characteristics of GRB200503A and GRB201009A
Divita Saraogi, Suman Bala, Jitendra Joshi +18
We present results of a comprehensive analysis of the polarization characteristics of GRB 200503A and GRB 201009A observed with the Cadmium Zinc Telluride Imager (CZTI) on board As…
A bright gamma-ray flare interpreted as a giant magnetar flare in NGC 253
D. Svinkin, D. Frederiks, K. Hurley +33
Magnetars are young, highly magnetized neutron stars that produce extremely rare giant flares of gamma-rays, the most luminous astrophysical phenomena in our Galaxy. The detection…
A Missing-Link in the Supernova-GRB Connection: The Case of SN 2012ap
Sayan Chakraborti, Alicia Soderberg, Laura Chomiuk +50
Gamma Ray Bursts (GRBs) are characterized by ultra-relativistic outflows, while supernovae are generally characterized by non-relativistic ejecta. GRB afterglows decelerate rapidly…
The ultraluminous GRB 110918A
D. D. Frederiks, K. Hurley, D. S. Svinkin +29
GRB 110918A is the brightest long GRB detected by Konus-WIND during its 19 years of continuous observations and the most luminous GRB ever observed since the beginning of the cosmo…
GRB 080407: an ultra-long burst discovered by the IPN
V. Pal'shin, K. Hurley, J. Goldsten +25
We present observations of the extremely long GRB 080704 obtained with the instruments of the Interplanetary Network (IPN). The observations reveal two distinct emission episodes,…
Extremely long hard bursts observed by Konus-Wind
V. Pal'shin, R. Aptekar, D. Frederiks +18
We report the observations of the prompt emission of the extremely long hard burst, GRB 060814B, discovered by Konus-Wind and localized by the IPN. The observations reveal a smooth…
IPN localizations of Konus short gamma-ray bursts
V. D. Pal'shin, K. Hurley, D. S. Svinkin +71
Between the launch of the \textit{GGS Wind} spacecraft in 1994 November and the end of 2010, the Konus-\textit{Wind} experiment detected 296 short-duration gamma-ray bursts (includ…
The Interplanetary Network Supplement to the Fermi GBM Catalog of Cosmic Gamma-Ray Bursts
K. Hurley, V. D. Pal'shin, R. L. Aptekar +37
We present Interplanetary Network (IPN) data for the gamma-ray bursts in the first Fermi Gamma-Ray Burst Monitor (GBM) catalog. Of the 491 bursts in that catalog, covering 2008 Jul…
Inverse Compton X-ray Emission from Supernovae with Compact Progenitors: Application to SN2011fe
R. Margutti, A. M. Soderberg, L. Chomiuk +35
We present a generalized analytic formalism for the inverse Compton X-ray emission from hydrogen-poor supernovae and apply this framework to SN2011fe using Swift-XRT, UVOT and Chan…
The Interplanetary Network Supplement to the Fermi GBM Catalog - An AO-2 and AO-3 Guest Investigator Project
K. Hurley, M. Briggs, V. Connaughton +37
In the first two years of operation of the Fermi GBM, the 9-spacecraft Interplanetary Network (IPN) detected 158 GBM bursts with one or two distant spacecraft, and triangulated the…
The Interplanetary Network Supplement to the BeppoSAX Gamma-Ray Burst Catalogs
K. Hurley, C. Guidorzi, F. Frontera +31
Between 1996 July and 2002 April, one or more spacecraft of the interplanetary network detected 787 cosmic gamma-ray bursts that were also detected by the Gamma-Ray Burst Monitor a…
Integrating the Fermi Gamma-Ray Burst Monitor into the 3rd Interplanetary Network
K. Hurley, M. Briggs, V. Connaughton +35
We are integrating the Fermi Gamma-Ray Burst Monitor (GBM) into the Interplanetary Network (IPN) of Gamma-Ray Burst (GRB) detectors. With the GBM, the IPN will comprise 9 experimen…
The Interplanetary Network Supplement to the HETE-2 Gamma-Ray Burst Catalog
K. Hurley, J. -L. Atteia, C. Barraud +43
Between 2000 November and 2006 May, one or more spacecraft of the interplanetary network (IPN) detected 226 cosmic gamma-ray bursts that were also detected by the FREGATE experimen…
A new analysis of the short-duration, hard-spectrum GRB 051103, a possible extragalactic SGR giant flare
K. Hurley, A. Rowlinson, E. Bellm +34
GRB 051103 is considered to be a candidate soft gamma repeater (SGR) extragalactic giant magnetar flare by virtue of its proximity on the sky to M81/M82, as well as its time histor…
