Distribution of the C statistic with applications to the sample mean of Poisson data

M. Bonamente

The C statistics, also known as the Cash statistic, is often used in astronomy for the analysis of low-count Poisson data. One of the challenges of the C statistic is that its prob…

Fermi and Swift Observations of GRB 190114C: Tracing the Evolution of High-Energy Emission from Prompt to Afterglow

M. Ajello, M. Arimoto, M. Axelsson +147

We report on the observations of gamma-ray burst (GRB) 190114C by the Fermi Gamma-ray Space Telescope and the Neil Gehrels Swift Observatory. The early-time observations reveal mul…

A decade of Gamma-Ray Bursts observed by -LAT: The 2 GRB catalog

M. Axelsson, E. Bissaldi, N. Omodei +1

The Large Area Telescope (LAT) aboard the spacecraft routinely observes high-energy emission from gamma-ray bursts (GRBs). Here we present the second catalog of LAT-detecte…

Description of atypical bursts seen slightly off-axis

N. Fraija, F. De Colle, P. Veres +5

The detection of gravitational waves together with their electromagnetic counterpart, in the gamma-ray burst GRB 170817A, marked a new era of multi-messenger astronomy. Several the…

How Pulses in Short Gamma-Ray Bursts Constrain HMXRB Evolution

Jon Hakkila, Robert D. Preece

We demonstrate how pulse structures in Short gamma-ray bursts (SGRBs), coupled with observations of GRB/GW 170817A, constrain the geometries of dying HMXRB systems composed of merg…

A Search for High-Energy Counterparts to Fast Radio Bursts

Virginia Cunningham, S. Bradley Cenko, Eric Burns +8

We report on a search for high-energy counterparts to fast radio bursts (FRBs) with the Fermi Gamma-ray Burst Monitor (GBM), Fermi Large Area Telescope (LAT), and the Neil Gehrels…

Constraining the magnetic field in the TeV halo of Geminga with X-ray Observation

Ruo-Yu Liu, Chong Ge, Xiao-Na Sun +1

Recently, the High Altitude Water Cherenkov (HAWC) collaboration reported the discovery of the TeV halo around the Geminga pulsar. The TeV emission is believed to originate from in…

Signatures from a quasi-spherical outflow and an off-axis top-hat jet launched in a merger of compact objects: An analytical approach

N. Fraija, D. Lopez-Camara, A. C. Caligula do E. S. Pedreira +3

The production of both gravitational waves and short gamma-ray bursts (sGRBs) is widely associated with the merger of compact objects. Several studies have modelled the evolution o…

Reverse Shock Emission Revealed in Early Photometry in the Candidate Short GRB 180418A

Rosa L. Becerra, Simone Dichiara, Alan M. Watson +14

We present observations of the possible short GRB 180418A in -rays, X-rays, and in the optical. Early optical photometry with the TAROT and RATIR instruments show a bright peak…

Fermi GBM GRBs with characteristics similar to GRB 170817A

A. von Kienlin, P. Veres, O. J. Roberts +11

We present a search for gamma-ray bursts in the Fermi-GBM 10 year catalog that show similar characteristics to GRB 170817A, the first electromagnetic counterpart to a GRB identifie…
