ENGRAVE follow-up of a type IIb supernova spatially coincident with the sub-threshold gravitational wave trigger S250818k
K. Ackley, M. T. Botticella, A. Boye +54
The candidate gravitational wave (GW) event S250818k was one of only three non-retracted LIGO-Virgo-KAGRA public alerts issued during the fourth observing run of the network (O4) w…
No Sign of a Magnetar Remnant Following the Kilonova-Producing Long GRB 211211A Years Later
Genevieve Schroeder, Ben Margalit, Brian D. Metzger +9
In addition to a -ray burst (GRB), the merger of two neutron stars may produce a temporarily or indefinitely stable neutron star remnant with a strong magnetic field (a "magnet…
EP241217a: a likely Type II GRB with an achromatic bump at z = 4.59
Hao Zhou, Jia Ren, Chen-Wei Wang +22
EP241217a is an X-ray transient detected by the Einstein Probe (EP) lasting for about 100 seconds and without accompanying -ray detection. The optical spectroscopy reveals the…
Gravitational Lensing in gamma-ray bursts
A. J. Levan, B. P. Gompertz, G. P. Smith +3
Gravitationally lensed Gamma-ray bursts (GRBs) offer critical advantages over other lensed sources. They can be detected via continuously operating detectors covering most of the s…
Multi-messenger Gravitational Lensing
Graham P. Smith, Tessa Baker, Simon Birrer +38
We introduce the rapidly emerging field of multi-messenger gravitational lensing - the discovery and science of gravitationally lensed phenomena in the distant universe through the…
