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…
SVOM GRB 250314A at z 7.3: an exploding star in the era of reionization
B. Cordier, J. Y. Wei, N. R. Tanvir +103
Most long Gamma-ray bursts originate from a rare type of massive stellar explosion. Their afterglows, while rapidly fading, can be initially extremely luminous at optical/near-infr…
The case of AT2022wtn: a Tidal Disruption Event in an interacting galaxy
F. Onori, M. Nicholl, P. Ramsden +35
We present the results from our multi-wavelength monitoring campaign of the transient AT2022wtn, discovered by the Zwicky Transient Facility in the nucleus of SDSSJ232323.79+104107…
Characterization of a peculiar Einstein Probe transient EP240408a: an exotic gamma-ray burst or an abnormal jetted tidal disruption event?
B. O'Connor, D. Pasham, I. Andreoni +30
We present the results of our multi-wavelength (X-ray to radio) follow-up campaign of the Einstein Probe transient EP240408a. The initial 10 s trigger displayed bright soft X-ray (…
Panning for gold with the Neil Gehrels Swift Observatory: an optimal strategy for finding the counterparts to gravitational wave events
R. A. J. Eyles-Ferris, P. A. Evans, A. A. Breeveld +17
The LIGO, Virgo and KAGRA gravitational wave observatories are currently undertaking their O4 observing run offering the opportunity to discover new electromagnetic counterparts to…
