Discovery and Extensive Follow-Up of SN 2024ggi, a nearby type IIP supernova in NGC 3621
Ting-Wan Chen, Sheng Yang, Shubham Srivastav +45
We present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 +/- 0.3 Mpc. The SN was caught 5.8 (+1.9 -2.9) hours after its expl…
The Extremely Metal-Poor SN 2023ufx: A Local Analog to High-Redshift Type II Supernovae
Michael A. Tucker, Jason Hinkle, Charlotte R. Angus +26
We present extensive observations of the Type II supernova (SN II) 2023ufx which is likely the most metal-poor SN II observed to-date. It exploded in the outskirts of a low-metalli…
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…
Anomaly Detection and Approximate Similarity Searches of Transients in Real-time Data Streams
P. D. Aleo, A. W. Engel, G. Narayan +29
We present LAISS (Lightcurve Anomaly Identification and Similarity Search), an automated pipeline to detect anomalous astrophysical transients in real-time data streams. We deploy…
Black-Hole-to-Halo Mass Relation From UNIONS Weak Lensing
Qinxun Li, Martin Kilbinger, Wentao Luo +17
This letter presents, for the first time, direct constraints on the black-hole-to-halo-mass relation using weak gravitational lensing measurements. We construct type I and type II…
SN 2020pvb: a Type IIn-P supernova with a precursor outburst
Nancy Elias-Rosa, Seán J. Brennan, Stefano Benetti +37
We present photometric and spectroscopic data sets for SN 2020pvb, a Type IIn-P supernova (SN) similar to SNe 1994W, 2005cl, 2009kn and 2011ht, with a precursor outburst detected (…
