Pulsed, Polarized X-ray Emission from Neutron Star Surfaces: the Effects of Vacuum Birefringence in the Magnetosphere
Hoa Dinh Thi, Matthew G. Baring, Kun Hu +4
Intense magnetic fields in the atmospheres of neutron stars render non-trivial angular dependence of intensity and polarization of soft X-ray emission originating from their surfac…
Neutron star heating vs. HST observations
Luis E. Rodríguez, Andreas Reisenegger, Denis González-Caniulef +5
Passively cooling neutron stars (NSs) should reach undetectably low surface temperatures K in less than yr. However, HST observations have revealed likely thermal…

Magnetar giant flares (MGFs) are rare, extremely bright bursts of gamma-rays from highly magnetized neutron stars. These events are challenging to identify because, at extragalacti…
GRB 250702B: Discovery of a Gamma-Ray Burst from a Black Hole Falling into a Star
Eliza Neights, Eric Burns, Chris L. Fryer +52
Gamma-ray bursts are the most luminous electromagnetic events in the universe. Their prompt gamma-ray emission has typical durations between a fraction of a second and several minu…
Vacuum birefringence and the polarized X-ray emission from a radio magnetar
Rachael E. Stewart, Hoa Dinh Thi, George Younes +13
Magnetars are isolated neutron stars with exceptionally strong surface fields exceeding G. Their bright X-ray emission probes physical regimes in which quantum electrodyn…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS
LAT Collaboration, S. Abdollahi, L. Baldini +586
Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
Afterglow Linear Polarization Signatures from Steep GRB Jets: Implications for Orphan Afterglows
Gal Birenbaum, Jonathan Granot, Paz Beniamini
Gamma-Ray Bursts (GRBs) are the strongest explosions in the Universe, and are powered by initially ultra-relativistic jets. The angular profile of GRB jets encodes important inform…
GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels
Dimple, B. P. Gompertz, A. J. Levan +85
Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…
