BL Lac host galaxies: how to systematically characterise them in optical-NIR spectroscopy
Gaia Delucchi, Tullia Sbarrato, Giorgio Calderone +3
Host galaxies of Active Galactic Nuclei give crucial information on the interaction between accreting Supermassive Black Holes and their surroundings, and on their common evolution…
Discovery and Analysis of Afterglows from Poorly Localised GRBs with the Gravitational-wave Optical Transient Observer (GOTO) All-sky Survey
Amit Kumar, B. P. Gompertz, B. Schneider +86
Gamma-ray bursts (GRBs), particularly those detected by wide-field instruments such as the Fermi/GBM, pose a challenge for optical follow-up due to their large initial localisation…
The radio flare and multi-wavelength afterglow of the short GRB 231117A: energy injection from a violent shell collision
G. E. Anderson, G. P. Lamb, B. P. Gompertz +64
We present the early radio detection and multi-wavelength modeling of the short gamma-ray burst (GRB) 231117A at redshift . The Australia Telescope Compact Array automatic…
First joint absorption and T-based metallicity measured in a GRB host galaxy at using JWST/NIRSpec
Anne Inkenhaag, Patricia Schady, Phil Wiseman +20
We present the first gamma-ray burst (GRB) host galaxy with a measured absorption line and electron temperature (T) based metallicity, using the temperature sensitive [OIII]$λ…
Swift Observations of Gaia BH3
Boris Sbarufatti, Renato Falomo, Aldo Treves
We present UV and X-ray observations, obtained with the Swift Observatory, of Gaia BH3 a binary system containing a 33 solar masses black hole discovered through Gaia astrometry. T…
