GRBs and Relativistic Transients in the 2040s
Nikhil Sarin, Andrew Levan, Nial Tanvir +9
Relativistic transients such as gamma-ray bursts (GRBs), jetted tidal disruption events, luminous fast blue optical transients, and fast X-ray transients, represent the brightest e…
Multi-messenger and time-domain astronomy in the 2040s
Samaya Nissanke, Nikhil Sarin, Chris Copperwheat +31
Multi-messenger astronomy will be transformed in the 2040s by an unprecedented volume of detections from next-generation gravitational wave, high-energy, and ultra-high energy neut…
The maximum offsets of binary neutron star mergers from host galaxies
Ilya Mandel, Om Sharan Salafia, Andrew Levan +1
We analytically derive, and illustrate with a population synthesis model, the maximum offset of binary neutron star mergers ejected from their host galaxies. This approximate maxim…
Unveiling the nature of the Einstein Probe transient EP 241021a
J. Quirola-Vásquez, P. G. Jonker, A. J. Levan +23
We present a multi-wavelength analysis of the fast X-ray transient EP 241021a, discovered by the Wide-field X-ray Telescope aboard the \emph{Einstein Probe} satellite on 2024 Octob…
AT 2018cow at ~5 years: additional evidence for a tidal disruption origin
Anne Inkenhaag, Andrew J. Levan, Andrew Mummery +1
The Luminous Fast Blue Optical Transient (LFBOT) AT 2018cow is the prototype of its class with an extensive set of multi-wavelength observations. Despite a rich data set there is,…
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 "magneta…
BGRem: A background noise remover for astronomical images based on a diffusion model
Rodney Nicolaas, Sascha Caron, Fiorenzo Stoppa +4
Context: Astronomical imaging aims to maximize signal capture while minimizing noise. Enhancing the signal-to-noise ratio directly on detectors is difficult and expensive, leading…
Luminous Fast Blue Optical Transients as very massive star core-collapse events
A. A. Chrimes, P. G. Jonker, A. J. Levan +1
Luminous Fast Blue Optical Transients (LFBOTs) are rare extragalactic events of unknown origin. Tidal disruptions of white dwarfs by intermediate mass black holes (BHs), mergers of…
White dwarf-neutron star binaries: a plausible pathway for long-duration gamma-ray bursts from compact object mergers?
A. A. Chrimes, N. Gaspari, A. J. Levan +7
Two long-duration gamma-ray bursts were recently discovered with kilonovae, the signature of r-process element production in a compact binary merger, rather than supernovae. This h…
Binary neutron star merger offsets from their host galaxies II. Short-duration gamma-ray bursts
N. Gaspari, A. J. Levan, A. A. Chrimes +1
The mergers of binary neutron stars (BNSs) and neutron star-black holes (NSBHs) binaries have long been linked to short-duration gamma-ray bursts (SGRBs). However, despite their st…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
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…
The Science of the Einstein Telescope
Adrian Abac, Raul Abramo, Simone Albanesi +485
Einstein Telescope (ET) is the European project for a gravitational-wave (GW) observatory of third-generation. In this paper we present a comprehensive discussion of its science ob…
A kinematically constrained kick distribution for isolated neutron stars
Paul Disberg, Nicola Gaspari, Andrew J. Levan
The magnitudes of the velocity kicks that neutron stars (NSs) obtain at their formation have long been a topic of discussion. In previous work, a novel method was proposed to deter…
Constraints on optical and near-infrared variability in the localisation of the long-period radio transient GLEAM-X J1627-52
J. D. Lyman, V. S. Dhillon, S. Kamann +5
GLEAM-X J1627-52 was discovered as a periodic (~18 min) radio signal over a duration of three months in 2018. It is an enigmatic example of a growing population of 'long-period rad…
