GRB 220706A: a gamma-ray burst with a month-long engine and a luminous supernova
Benjamin P. Gompertz, Nusrin Habeeb, Dheeraj R. Pasham +30
While the progenitors of many long gamma-ray bursts (GRBs) are well established as the core collapse of very massive, envelope-stripped, rapidly-rotating stars, it has been suggest…
Low-hard to high-soft spectral state transitions in the faintest early-X-ray-detected optical tidal disruption event TDE 2025aarm
Pietro Baldini, Arne Rau, Andrea Merloni +11
We report the X-ray and optical spectroscopic properties of TDE 2025aarm, the second closest tidal disruption event (TDE) discovered to date. The proximity of this source, combined…
Discovering High- BL Lacs Using Swift/UVOT and SARA Observations with the Dropout Technique
Y. Sheng, K. Imam, A. Kaur +14
Measuring spectroscopic redshifts for BL Lacertae (BL Lac) objects, a class of blazar, is challenging because their optical spectrum lacks, or has weak, emission lines ( equivalent…
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…
Discovery and Follow-up of the Unusual Nuclear Transient OGLE17aaj
M. Gromadzki, A. Hamanowicz, L. Wyrzykowski +31
We report on the discovery and follow-up of a peculiar transient, OGLE17aaj, which occurred in the nucleus of a weakly active galaxy. We investigate whether it can be interpreted a…
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…
