Brightness, Colour, Polarisation: A Multi-Instrument Observation Campaign of the Gorizont-6 Satellite
Robert J. S Airey, Paul Chote, Klaas Wiersema +15
We present a coordinated multi-instrument photometric and polarimetric study of the defunct geosynchronous satellite, Gorizont-6. This observation campaign combined wide-field mult…
SN 2024abfl: A Low-Luminosity Type IIP Supernova in NGC 2146 from a Low-Mass Red Supergiant Progenitor
Xiaohan Chen, Ning-Chen Sun, Qiang Xi +44
Type IIP supernovae (SNe IIP) exhibit a significant diversity in their explosion properties, yet the physical mechanisms driving this diversity remain unknown. In this work, we pre…
SN 2025coe: A Multiple-Peaked Calcium-Strong Transient from A White-Dwarf Progenitor
Chun Chen, Ning-Chen Sun, Qiang Xi +25
SN 2025coe is a calcium-strong transient located at an extremely large projected offset 39.3 kpc from the center of its host, the nearby early-type galaxy NGC 3277 at a dista…
SN 2024aecx: a fast-evolving Type IIb supernova with a prominent shock-cooling peak
Qiang Xi, Ning-Chen Sun, David Aguado +36
SN 2024aecx is a nearby (11 Mpc) Type IIb SN discovered within 1 d after explosion. In this paper we report high-cadence photometric (typically 0.51 day) and spec…
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…
EP241021a: a months-duration X-ray transient with luminous optical and radio emission
Shu Xinwen, Yang Lei, Yang Haonan +82
We present the discovery of a peculiar X-ray transient, EP241021a, by the Einstein Probe (EP) mission, and the results from multiwavelength follow-up observations. The transient wa…
Spectropolarimetry of SN 2023ixf reveals both circumstellar material and helium core to be aspherical
Manisha Shrestha, Sabrina DeSoto, David J. Sand +33
We present multi-epoch optical spectropolarimetric and imaging polarimetric observations of the nearby Type II supernova (SN) 2023ixf discovered in M101 at a distance of 6.85 Mpc.…
Polarized kilonovae from black hole-neutron star mergers
M. Bulla, K. Kyutoku, M. Tanaka +6
We predict linear polarization for a radioactively-powered kilonova following the merger of a black hole and a neutron star. Specifically, we perform 3-D Monte Carlo radiative tran…
The luminous host galaxy, faint supernova and rapid afterglow rebrightening of GRB 100418A
A. de Ugarte Postigo, C. C. Thoene, K. Bensch +35
Long gamma-ray bursts give us the chance to study both their extreme physics and the star-forming galaxies in which they form. GRB 100418A, at a z = 0.6239, had a bright optical an…
VLT/X-shooter GRBs: Individual extinction curves of star-forming regions
T. Zafar, D. Watson, P. Møller +14
The extinction profiles in Gamma-Ray Burst (GRB) afterglow spectral energy distributions (SEDs) are usually described by the Small Magellanic Cloud (SMC)-type extinction curve. In…
Broadband modelling of short gamma-ray bursts with energy injection from magnetar spin-down and its implications for radio detectability
B. P. Gompertz, A. J. van der Horst, P. T. O'Brien +2
The magnetar model has been proposed to explain the apparent energy injection in the X-ray light curves of short gamma-ray bursts (SGRBs), but its implications across the full broa…
Fast infrared variability from a relativistic jet in GX 339-4
P. Casella, T. J. Maccarone, K. O'Brien +14
We present the discovery of fast infrared/X-ray correlated variability in the black-hole transient GX 339-4. The source was observed with sub-second time resolution simultaneously…
