Energy-dependent polarization of Gamma-Ray Bursts' prompt emission with the POLAR and POLAR-2 instruments
Nicolas De Angelis, J. Michael Burgess, Franck Cadoux +10
Gamma-Ray Bursts are among the most powerful events in the Universe. Despite half a century of observations of these transient sources, many open questions remain about their natur…
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,…
Misidentification of Short GRBs as Magnetars in Nearby Galaxies
E. C. Schösser, J. M. Burgess, J. Greiner
Context. Recent observations of GRB 200415A, a short and very bright pulse of -rays, have been claimed to be an extragalactic magnetar giant flare (MGF) whose proposed host gala…
Advancing the Landscape of Multimessenger Science in the Next Decade
Kristi Engel, Tiffany Lewis, Marco Stein Muzio +91
The last decade has brought about a profound transformation in multimessenger science. Ten years ago, facilities had been built or were under construction that would eventually dis…
The Future of Gamma-Ray Experiments in the MeV-EeV Range
Kristi Engel, Jordan Goodman, Petra Huentemeyer +95
Gamma-rays, the most energetic photons, carry information from the far reaches of extragalactic space with minimal interaction or loss of information. They bring messages about par…
Improving INTEGRAL/SPI data analysis of GRBs
Björn Biltzinger, Jochen Greiner, J. Michael Burgess +1
INTEGRAL/SPI is a coded mask instrument observing since 2002 in the keV to MeV energy range, which covers the peak of the spectrum of most Gamma-Ray Bursts (GRBs). Since its…
Assessing coincident neutrino detections using population models
F. Capel, J. M. Burgess, D. J. Mortlock +1
Several tentative associations between high-energy neutrinos and astrophysical sources have been recently reported, but a conclusive identification of these potential neutrino emit…
Gamma-Ray Polarization Results of the POLAR Mission and Future Prospects
M. Kole, N. de Angelis, J. M. Burgess +14
Despite over 50 years of Gamma-Ray Burst (GRB) observations many open questions remain about their nature and the environments in which the emission takes place. Polarization measu…
The POLAR Gamma-Ray Burst Polarization Catalog
Merlin Kole, Nicolas De Angelis, Francesco Berlato +18
Despite over 50 years of research, many open questions remain about the origin and nature of GRBs. Polarization measurements of the prompt emission of these extreme phenomena have…
Improved Fermi-GBM GRB localizations using BALROG
F. Berlato, J. Greiner, J. Michael Burgess
The localizations of gamma-ray bursts (GRBs) detected with the Gamma-ray Burst Monitor (GBM) onboard the Fermi satellite are known to be affected by significant systematic errors o…
Time-Resolved GRB Polarization with POLAR and GBM
J. Michael Burgess, M. Kole, F. Berlato +5
Simultaneous -ray measurements of gamma-ray burst (GRB) spectra and polarization offer a unique way to determine the underlying emission mechanism(s) in these objects as well as…
Gamma-ray bursts as cool synchrotron sources
J. Michael Burgess, Damien Bégué, Ana Bacelj +3
Gamma-ray bursts are the most energetic electromagnetic sources in the Universe. Their prompt gamma-ray radiation corresponds to an energy release of 1E42-1E47J. Fifty years after…
The peculiar physics of GRB 170817A and their implications for short GRBs
D. Bégué, J. Michael Burgess, J. Greiner
The unexpected nearby gamma-ray burst GRB 170817A associated with the LIGO binary neutron star merger event GW170817 presents a challenge to the current understanding of the emissi…
Viewing short Gamma-ray Bursts from a different angle
J. Michael Burgess, Jochen Greiner, Damien Begue +3
The recent coincident detection of gravitational waves (GW) from a binary neutron star merger with aLIGO/Virgo and short-lived gamma-ray emission with Fermi/GBM (called GW 170817)…
The X-ray counterpart to the gravitational wave event GW 170817
E. Troja, L. Piro, H. van Eerten +31
A long-standing paradigm in astrophysics is that collisions- or mergers- of two neutron stars (NSs) form highly relativistic and collimated outflows (jets) powering gamma-ray burst…
Is Spectral Width a Reliable Measure of GRB Emission Physics?
J. Michael Burgess
The spectral width and sharpness of unfolded, observed GRB spectra have been presented as a new tool to infer physical properties about GRB emission via spectral fitting of empiric…

J. Greiner, J. M. Burgess, V. Savchenko +1
In view of the recent report by Connaughton we analyse continuous TTE data of Fermi-GBM around the time of the gravitational wave event GW 150914. We find that after proper account…
The anatomy of a long gamma-ray burst: a simple classification scheme for the emission mechanism(s)
Damien Bégué, J. Michael Burgess
Ultra-relativistic motion and efficient conversion of kinetic energy to radiation are required by gamma-ray burst (GRB) observations, yet they are difficult to simultaneously achie…
