Evidence of Supernova Between Formation of Stellar Populations in a Globular Cluster
Evan N. Kirby, Roman Gerasimov, Alice Cai +3
Globular clusters do not undergo conventional chemical evolution driven by supernova enrichment. Instead, they exhibit unique abundance patterns of the light elements, which cannot…
Discovery of 30 Repeating Fast Radio Burst Sources and Uniform Population Statistics of 80 Repeating Sources from CHIME/FRB
Amanda M. Cook, Kaitlyn Shin, Ziggy Pleunis +44
We present 30 newly discovered repeating fast radio burst (FRB) sources from the second catalog of bursts detected by the FRB backend on the Canadian Hydrogen Intensity Mapping Exp…
-process Abundance Dispersion in the Globular Cluster M5 using Keck Archival Data
Pranav Nalamwar, Evan N. Kirby, Alice Cai
We studied RGB stars in the mildly metal-rich globular cluster M5 ([Fe/H] ) using archival high-resolution spectra from the Keck Observatory archive (KOA) to better u…
FRB 20250316A: A Brilliant and Nearby One-Off Fast Radio Burst Localized to 13 parsec Precision
FRB Collaboration, Thomas C. Abbott, Daniel Amouyal +83
Precise localizations of a small number of repeating fast radio bursts (FRBs) using very long baseline interferometry (VLBI) have enabled multiwavelength follow-up observations rev…
Discovery and Localization of the Swift-Observed FRB 20241228A in a Star-forming Host Galaxy
Alice P. Curtin, Shion Andrew, Sunil Simha +27
On 2024 December 28, CHIME/FRB detected the thus-far non-repeating FRB 20241228A with a real-time signal-to-noise ratio of . Approximately 112~s later, the X-ray Telescope onb…
