Flashlights: Prospects for constraining the Initial Mass Function around cosmic noon with caustic-crossing events
Ashish Kumar Meena, Sung Kei Li, Adi Zitrin +7
The Flashlights program with the Hubble Space Telescope imaged the six Hubble Frontier Fields galaxy clusters in two epochs and detected twenty transients. These are primarily expe…
A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
Spectroscopy of AT 2016blu's recurring supernova impostor outbursts
Mojgan Aghakhanloo, Nathan Smith, Jennifer E. Andrews +7
We present spectra of the supernova (SN) impostor AT 2016blu spanning over a decade. This transient exhibits quasiperiodic outbursts with a 113 d period, likely triggered by…
Multi-epoch leptohadronic modeling of neutrino source candidate blazar PKS 0735+178
A. Omeliukh, S. Garrappa, V. Fallah Ramazani +12
The origin of the astrophysical neutrino flux discovered by IceCube remains largely unknown. Several individual neutrino source candidates were observed. Among them is the gamma-ra…
The Luminous, Slow-Rising Orphan Afterglow AT2019pim as a Candidate Moderately Relativistic Outflow
Daniel A. Perley, Anna Y. Q. Ho, Michael Fausnaugh +34
Classical gamma-ray bursts (GRBs) have two distinct emission episodes: prompt emission from ultrarelativistic ejecta and afterglow from shocked circumstellar material. While both c…
Multi-wavelength study of OT 081: broadband modelling of a transitional blazar
MAGIC Collaboration, H. Abe, S. Abe +270
OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…
