A Proliferated Space Architecture for Time-Domain Astrophysics
Daniel Kocevski, Eric Burns, Thomas Barclay +58
Time-Domain and Multi-Messenger Astrophysics (TDAMM) is entering a discovery-rich but follow-up-limited era, creating an urgent need for responsive, multiwavelength space-based cap…
A Search for GeV Emission from Magnetar Giant Flare Candidates with Fermi-LAT
Vikas Chand, Michela Negro, Nicola Omodei +5
The discovery of delayed GeV emission from the extragalactic magnetar giant flare (MGF) GRB 200415A, located in the nearby Sculptor galaxy, revealed for the first time that these r…
Fast-Cooling Synchrotron Prompt Emission from Internal Shocks in GRB 241030A
Varun, Bin-Bin Zhang, Xiao-Hong Zhao +3
We present a time-resolved, joint Swift-Fermi spectral study of GRB 241030A (z=1.411) that cleanly isolates the synchrotron origin of its prompt emission and favors a matter-domina…
GRB 200415A: A Short Gamma-Ray Burst from a Magnetar Giant Flare?
Jun Yang, Vikas Chand, Bin-Bin Zhang +16
The giant flares of soft gamma-ray repeaters (SGRs) have long been proposed to contribute to at least a subsample of the observed short gamma-ray bursts (GRBs). In this paper, we p…
Magnetar Giant Flare Originated GRB 200415A: Transient GeV emission, Time-Resolved Correlation, and Implications
Vikas Chand, Jagdish C. Joshi, Rahul Gupta +12
Giant flares (GFs) are unusual bursts from soft gamma-ray repeaters (SGRs) that release an enormous amount of energy in a fraction of a second. The afterglow emission of these SGR-…
Peculiar prompt emission and afterglow in H.E.S.S. detected GRB 190829A
Vikas Chand, Ankush Banerjee, Rahul Gupta +10
We present the results of a detailed investigation of the prompt and afterglow emission in the HESS detected GRB 190829A. Swift and Fermi observations of the prompt phase of this G…
MAGICal GRB 190114C: Implications of cutoff in the spectrum at sub- energies
Vikas Chand, Partha Sarathi Pal, Ankush Banerjee +3
GRB 190114C is an unusual gamma-ray burst (GRB) due to its detection at sub- energies by MAGIC, seen at redshift z = 0.42. This burst is one of the brightest GRB detected by \…
AstroSat-CZTI detection of variable prompt emission polarization in GRB 171010A
Vikas Chand, Tanmoy Chattopadhyay, Gor Oganesyan +5
We present spectro-polarimetric analysis of \thisgrb\ using data from \asat, \fermi, and \swift, to provide insights into the physical mechanisms of the prompt radiation and the je…
Violation of synchrotron line of death by the highly polarized
Vikas Chand, Tanmoy Chattopadhyay, S. Iyyani +7
is one of the brightest gamma-ray bursts (GRBs) observed with Gamma-ray Burst Monitor (GBM) in the energy range of keV, while at the same time it…
Surprise in simplicity: an unusual spectral evolution of a single pulse GRB 151006A
R. Basak, S. Iyyani, V. Chand +4
We present a detailed analysis of GRB 151006A, the first GRB detected by Astrosat CZT Imager (CZTI). We study the long term spectral evolution by exploiting the capabilities of \em…
Prompt emission polarimetry of Gamma Ray Bursts with ASTROSAT CZT-Imager
Tanmoy Chattopadhyay, Santosh V. Vadawale, E. Aarthy +10
X-ray and Gamma-ray polarization measurements of the prompt emission of Gamma-ray bursts (GRBs) are believed to be extremely important for testing various models of GRBs. So far, t…
AstroSat CZT Imager observations of GRB 151006A: timing, spectroscopy, and polarisation study
A. R. Rao, Vikas Chand, M. K. Hingar +24
AstroSat is a multi-wavelength satellite launched on 2015 September 28. The CZT Imager of AstroSat on its very first day of operation detected a long duration gamma-ray burst (GRB)…
