Broad-band Spectral Modeling of Prompt Emission from Gamma-Ray Bursts Observed by the Transiting Exoplanet Survey Satellite
Rahul Jayaraman, Michael Fausnaugh, George Ricker +1
Optical observations of gamma-ray bursts (GRBs) contemporaneous with their prompt high-energy emission are rare, but they can provide insights into the physical processes underlyin…
Gamma-Ray Bursts Observed by the Transiting Exoplanet Survey Satellite: Prompt Optical Counterparts and Afterglows of Swift-XRT Localized GRBs
Rahul Jayaraman, Michael Fausnaugh, George R. Ricker +1
Very few detections have been made of optical flashes contemporaneous with prompt high-energy emission from a gamma-ray burst (GRB). In this work, we present and analyze light curv…
Four years of Type Ia Supernovae Observed by TESS: Early Time Light Curve Shapes and Constraints on Companion Interaction Models
M. M. Fausnaugh, P. J. Vallely, M. A. Tucker +10
We present 307 Type Ia supernova (SN) light curves from the first four years of the TESS mission. We use this sample to characterize the shapes of the early time light curves, meas…
Observations of GRB 230307A by TESS
Michael M. Fausnaugh, Rahul Jayaraman, Roland Vanderspek +13
We present the TESS light curve of GRB 230307A. We find two distinct components: a bright, prompt optical component at the time of the Fermi observation that peaked at TESS magnitu…
A helium-burning white dwarf binary as a supersoft X-ray source
J. Greiner, C. Maitra, F. Haberl +12
Type Ia supernovae are cosmic distance indicators, and the main source of iron in the Universe, but their formation paths are still debated. Several dozen supersoft X-ray sources,…
Searching for Gravitational-Wave Counterparts using the Transiting Exoplanet Survey Satellite
Geoffrey Mo, Rahul Jayaraman, Michael Fausnaugh +3
In 2017, the LIGO and Virgo gravitational wave (GW) detectors, in conjunction with electromagnetic (EM) astronomers, observed the first GW multi-messenger astrophysical event, the…
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 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…
Spectral Lag Relations in GRB Pulses Detected with HETE-2
M. Arimoto, N. Kawai, K. Asano +36
Using a pulse-fit method, we investigate the spectral lags between the traditional gamma-ray band (50-400 keV) and the X-ray band (6-25 keV) for 8 GRBs with known redshifts (GRB 01…
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…
