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…
