Temporal and Spectral Evolution of Gamma-ray Burst Broad Pulses: Identification of High Latitude Emission in the Prompt Emission
Donggeun Tak, Z. Lucas Uhm, Judith Racusin +5
We perform a detailed analysis on broad pulses in bright Gamma-ray bursts (GRBs) to understand the evolution of GRB broad pulses. Using the temporal and spectral properties, we tes…
Evidence of High-latitude Emission in the Prompt Phase of GRBs: How Far from the Central Engine are the GRBs Produced?
Z. Lucas Uhm, Donggeun Tak, Bing Zhang +5
One of the difficulties in nailing down the physical mechanism of gamma-ray bursts (GRBs) comes from the fact that there has been no clear observational evidence on how far from th…
Current and future gamma-ray searches for dark-matter annihilation beyond the unitarity limit
Donggeun Tak, Matthew Baumgart, Nicholas L. Rodd +1
For decades, searches for electroweak-scale dark matter (DM) have been performed without a definitive detection. This lack of success may hint that DM searches have focused on the…
Probing the multiwavelength emission scenario of GRB 190114C
Marc Klinger, Donggeun Tak, Andrew M. Taylor +1
Multiwavelength observation of the gamma-ray burst, GRB 190114C, opens a new window for studying the emission mechanism of GRB afterglows. Its Very-High-Energy (VHE; …
