Optimizing Kilonova Searches: A Case Study of the Type IIb SN 2025ulz in the Localization Volume of the Low-Significance Gravitational Wave Event S250818k
Noah Franz, Bhagya Subrayan, Charles D. Kilpatrick +54
Kilonovae, the ultraviolet/optical/infrared counterparts to binary neutron star mergers, are an exceptionally rare class of transients. Optical follow-up campaigns are plagued by c…
The Multi-Wavelength Context of Delayed Radio Emission in TDEs: Evidence for Accretion-Driven Outflows
Kate D. Alexander, Raffaella Margutti, Sebastian Gomez +20
Recent observations presented in Cendes et al. (2024a) show that optically selected tidal disruption events (TDEs) commonly produce delayed radio emission that can peak years post-…
DASCH: Bringing 100+ Years of Photographic Data into the 21st Century and Beyond
Peter K. G. Williams
The Harvard College Observatory was the preeminent astronomical data center of the early 20th century: it gathered and archived an enormous collection of glass photographic plates…
PS1-11aop: Probing the Mass Loss History of a Luminous Interacting Supernova Prior to its Final Eruption with Multi-wavelength Observations
Adaeze L. Ibik, Maria R. Drout, Raffaela Margutti +14
Luminous interacting supernovae are a class of stellar explosions whose progenitors underwent vigorous mass loss in the years prior to core-collapse. While the mechanism by which t…
A Volume-Limited Radio Search for Magnetic Activity in 140 Exoplanets with the Very Large Array
Kevin N. Ortiz Ceballos, Yvette Cendes, Edo Berger +1
We present results from a search for radio emission in 77 stellar systems hosting 140 exoplanets, predominantly within 17.5 pc using the Very Large Array (VLA) at GHz. This i…
Large Synthetic Data from the arXiv for OCR Post Correction of Historic Scientific Articles
Jill P. Naiman, Morgan G. Cosillo, Peter K. G. Williams +1
Scientific articles published prior to the "age of digitization" (~1997) require Optical Character Recognition (OCR) to transform scanned documents into machine-readable text, a pr…
K2 Ultracool Dwarfs Survey. V. High superflare rates on rapidly rotating late-M dwarfs
Rishi R. Paudel, John E. Gizis, D. J. Mullan +4
We observed strong superflares (defined as flares with energy in excess of 10^33 erg) on three late-M dwarfs: 2MASS J08315742+2042213 (hereafter 2M0831+2042; M7 V), 2MASS J08371832…
M Dwarf Activity in the Pan-STARRS 1 Medium-Deep Survey: First Catalog and Rotation Periods
Erin Kado-Fong, Peter K. G. Williams, Andrew W. Mann +9
We report on an ongoing project to investigate activity in the M dwarf stellar population observed by the Pan-STARRS 1 Medium Deep Survey (PS1-MDS). Using a custom-built pipeline,…
The First Millimeter Detection of a Non-Accreting Ultracool Dwarf
P. K. G. Williams, S. L. Casewell, C. R. Stark +3
The well-studied M9 dwarf TVLM 513-46546 is a rapid rotator (P_rot ~ 2 hr) hosting a stable, dipolar magnetic field of ~3 kG surface strength. Here we report its detection with ALM…
Trends in Ultracool Dwarf Magnetism. II. The Inverse Correlation Between X-ray Activity and Rotation as Evidence for a Bimodal Dynamo
B. A. Cook, P. K. G. Williams, E. Berger
Observations of magnetic activity indicators in solar-type stars exhibit a relationship with rotation with an increase until a "saturation" level and a moderate decrease in activit…
