JWST and HST observations of the host galaxy and supernova, SN 2024aihh in EP240801a at z=1.67

Agnes P. C. van Hoof, Andrew J. Levan, Peter G. Jonker +15

We present James Webb Space Telescope (JWST) and Hubble Space Telescope (HST) observations of the counterpart of EP240801a, at z=1.67, the first fast X-ray transient (FXT) identifi…

EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?

P. G. Jonker, A. J. Levan, Xing Liu +41

Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…

A Panchromatic View of Late-time Shock Power in the Type II Supernova 2023ixf

W. V. Jacobson-Galán, L. Dessart, C. D. Kilpatrick +39

We present multi-wavelength observations of the type II supernova (SN II) 2023ixf during its first two years of evolution. We combine ground-based optical/NIR spectroscopy with Hub…

The day-long, repeating GRB 250702BDE / EP250702a: A unique extragalactic transient

Andrew J. Levan, Antonio Martin-Carrillo, Tanmoy Laskar +42

Gamma-ray bursts (GRBs) are singular outbursts of high-energy radiation with durations typically lasting from milliseconds to minutes and, in extreme cases, a few hours. They are a…

The Carnegie Supernova Project II. Observations of SN 2014ab possibly revealing a 2010jl-like SN IIn with pre-existing dust

T. J. Moriya, M. D. Stritzinger, F. Taddia +18

We present optical and near-infrared photometry and spectroscopy of the Type IIn supernova (SN) 2014ab, obtained by the Carnegie Supernova Project II (CSP-II) and initiated immedia…

Observational constraints on the optical and near-infrared emission from the neutron star-black hole binary merger S190814bv

K. Ackley, L. Amati, C. Barbieri +151

On 2019 August 14, the LIGO and Virgo interferometers detected a high-significance event labelled S190814bv. Preliminary analysis of the GW data suggests that the event was likely…
