A Panchromatic View of Late-time Shock Power in the Type II Supernova 2023ixf

W. V. Jacobson-Galán, L. Dessart, C. D. Kilpatrick +39

We present multi-wavelength observations of the type II supernova (SN II) 2023ixf during its first two years of evolution. We combine ground-based optical/NIR spectroscopy with Hub…

Seeing the Outer Edge of the Infant Type Ia Supernova 2024epr in the Optical and Near Infrared

W. B. Hoogendam, D. O. Jones, C. Ashall +30

We present optical-to-near-infrared (NIR) photometry and spectroscopy of the Type Ia supernova (SN Ia) 2024epr, including NIR spectra observed within two days of first light. The e…

Identification of the optical counterpart of the fast X-ray transient EP240414a

S. Srivastav, T. -W. Chen, J. H. Gillanders +26

Fast X-ray transients (FXTs) are extragalactic bursts of X-rays first identified in archival X-ray data, and now routinely discovered by the Einstein Probe in real time, which is c…

Sudden polarization angle jumps of the repeating fast radio burst FRB 20201124A

J. R. Niu, W. Y. Wang, J. C. Jiang +41

We report the first detection of polarization angle (PA) orthogonal jumps, a phenomenon previously only observed from radio pulsars, from a fast radio burst (FRB) source FRB 202011…

SN 2024ggi in NGC 3621: Rising Ionization in a Nearby, CSM-Interacting Type II Supernova

W. V. Jacobson-Galán, K. W. Davis, C. D. Kilpatrick +28

We present UV/optical/NIR observations and modeling of supernova (SN) 2024ggi, a type II supernova (SN II) located in NGC 3621 at 7.2 Mpc. Early-time ("flash") spectroscopy of SN 2…

Discovery of the optical and radio counterpart to the fast X-ray transient EP240315a

J. H. Gillanders, L. Rhodes, S. Srivastav +36

Fast X-ray Transients (FXTs) are extragalactic bursts of soft X-rays first identified >10 years ago. Since then, nearly 40 events have been discovered, although almost all of these…
