How Distance Affects GRB Prompt Emission Measurements
Michael J. Moss, Amy Y. Lien, S. Bradley Cenko +2
We investigated how Gamma-Ray Burst (GRB) prompt emission measurements are affected by increasing distance to the source. We selected a sample of 26 bright GRBs with measured redsh…
BatAnalysis -- A Comprehensive Python Pipeline for Swift BAT Time-Tagged Event Data Analysis
Tyler Parsotan, David M. Palmer, Samuele Ronchini +7
The Swift Burst Alert Telescope (BAT) is a coded aperture gamma-ray instrument with a large field of view that was designed to detect and localize transient events. When a transien…
The 157-month Swift-BAT All-Sky Hard X-Ray Survey
Amy Y. Lien, Hans Krimm, Craig Markwardt +12
The Burst Alert Telescope (BAT) onboard the Neil Gehrels Swift observatory has been serving as a survey instrument for the hard X-ray sky, and has detected thousands of X-ray sourc…
Constraints on diffuse X-ray Emission from the TeV halo Candidate HESS J1813-126
David Guevel, Kim L Page, Kaya Mori +2
Extended regions of very high energy -ray emission associated with middle-aged pulsars have been found by -ray observatories. These regions, called TeV halos or pulsar halo…
GRB220831A: a hostless, intermediate Gamma-ray burst with an unusual optical afterglow
James Freeburn, Brendan O'Connor, Jeff Cooke +20
GRB220831A is a gamma-ray burst (GRB) with a duration and spectral peak energy that places it at the interface between the distribution of long-soft and short-hard GRBs. In thi…
Characterization of a peculiar Einstein Probe transient EP240408a: an exotic gamma-ray burst or an abnormal jetted tidal disruption event?
B. O'Connor, D. Pasham, I. Andreoni +30
We present the results of our multi-wavelength (X-ray to radio) follow-up campaign of the Einstein Probe transient EP240408a. The initial 10 s trigger displayed bright soft X-ray (…
