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…
A Spectropolarimetric Study of Pictor A Radio Galaxy with MeerKAT
Lexy A. L. Andati, Lerato M. Baidoo, Athanaseus J. T. Ramaila +3
We present the results of a polarimetric study from our new high-sensitivity L-band (0.8--1.7 GHz) observation of Pictor A with the MeerKAT radio telescope. We confirm the presence…
Sardinia Radio Telescope observations of the Coma Cluster
M. Murgia, F. Govoni, V. Vacca +25
We present deep total intensity and polarization observations of the Coma cluster at 1.4 and 6.6 GHz performed with the Sardinia Radio Telescope. By combining the single-dish 1.4 G…
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…
