The BTSbot-nearby discovery of SN 2024jlf: rapid, autonomous follow-up probes interaction in an 18.5 Mpc Type IIP supernova

Nabeel Rehemtulla, W. V. Jacobson-Galán, Avinash Singh +27

We present observations of the Type IIP supernova (SN) 2024jlf, including spectroscopy beginning just 0.7 days (17 hours) after first light. Rapid follow-up was enabled by th…

The Nature of Optical Afterglows Without Gamma-ray Bursts: Identification of AT2023lcr and Multiwavelength Modeling

Maggie L. Li, Anna Y. Q. Ho, Geoffrey Ryan +29

In the past few years, the improved sensitivity and cadence of wide-field optical surveys have enabled the discovery of several afterglows without associated detected gamma-ray bur…

Sample of hydrogen-rich superluminous supernovae from the Zwicky Transient Facility

P. J. Pessi, R. Lunnan, J. Sollerman +26

Hydrogen-rich superluminous supernovae (SLSNe II) are rare. The exact mechanism producing their extreme light curve peaks is not understood. Analysis of single events and small sam…

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 Analysis of AT 2023sva: a Luminous Orphan Afterglow With Evidence for a Structured Jet

Gokul P. Srinivasaragavan, Daniel A. Perley, Anna Y. Q. Ho +50

We present multi-wavelength analysis of ZTF23abelseb (AT 2023sva), an optically discovered fast-fading ( mag in days), luminous ( mag) an…

Optical and Radio Analysis of Systematically Classified Broad-lined Type Ic Supernovae from the Zwicky Transient Facility

Gokul P. Srinivasaragavan, Sheng Yang, Shreya Anand +35

We study a magnitude-limited sample of 36 Broad-lined Type Ic Supernovae (SNe Ic-BL) from the Zwicky Transient Facility Bright Transient Survey (detected between March 2018 and Aug…
