The fraction of periodic SN Ib/c light curves
Asaf Horowicz, Eran O. Ofek, Avishay Gal-Yam
Periodic luminosity modulations have been recently identified for the stripped-envelope supernovae SN 2022jli and SN 2022esa, motivating a systematic search for a similar behavior…
Single object observations: Large telescopes vs. multiple small telescopes
Sagi Ben-Ami, Eran Oded Ofek
A significant fraction of large-telescope observing time is devoted to single-object spectroscopy and photometry. We compare the cost-effectiveness of different telescope architect…
Empty Shelves or Lost Keys? Recall Is the Bottleneck for Parametric Factuality
Nitay Calderon, Eyal Ben-David, Zorik Gekhman +2
Standard factuality evaluations of LLMs treat all errors alike, obscuring whether failures arise from missing knowledge (empty shelves) or from limited access to encoded facts (los…
Constraints on Late-Time Flaring from Luminous Fast Blue Optical Transients using the Transiting Exoplanet Survey Satellite and the Zwicky Transient Facility
Rahul Jayaraman, Anna Y. Q. Ho, Michael M. Fausnaugh +14
The Luminous Fast Blue Optical Transient (LFBOT) AT2022tsd exhibited minutes-timescale optical flares in the tens of days following the initial transient event, likely due to a cen…
Mapping the Landscape of M Dwarf X-ray Flares: New Discoveries in Context
Imri A. Dickstein, Maayane T. Soumagnac, Eran O. Ofek +4
We report the discovery of 11 X-ray flares from 7 M dwarfs previously unknown to exhibit flaring activity, by cross-matching eROSITA observations of bright, nearby M dwarfs with th…
Early Multiwavelength Observations of AT 2026fgk: The Luminous Afterglow to Sub-luminous GRB 260310A, Identified Independently of a Gamma-ray Trigger
K. -R. Hinds, A. Y. Q. Ho, Y. Wagh +103
The origins of sub-luminous (\,erg\,s) gamma-ray bursts (GRBs) associated with broad-lined Type~Ic supernovae (Ic-BL SNe) are poorly…
