In-Situ Star Formation in a Thick Disk: A Model for Metal Enrichment of Mrk 573
Hannalore J. Gerling-Dunsmore, Mitchell C. Begelman, Jared A. Goldberg +2
Recent observations of the nearby Seyfert galaxy Mrk 573 found that the galactic nucleus and bicone regions surrounding the jet are significantly metal-enriched. In this paper, we…
Evidence for Asymmetric Ejecta and Circumstellar Material in SN 2023ixf Inferred from Extensive Nebular-phase Observations
Brian Hsu, Nathan Smith, K. Azalee Bostroem +34
We present extensive optical and near-infrared (NIR) observations of the nearby Type II supernova (SN II) 2023ixf in the nebular phase from +89 days to +749 days after explosion, s…
Traces of Helium Detected in Type Ic Supernova 2014L
Jing Lu, Wolfgang E. Kerzendorf, John T. O'Brien +6
The absence of helium features in optical spectra is one of the classification criteria for Type Ic supernovae (SNe Ic). However, it is highly debated whether helium is truly absen…
Radial Velocity Evidence for a Post-Mass-Transfer Massive Binary System NaSt1
Kittipong Wangnok, Samaporn Tinyanont, Ryan M. Lau +11
We present multi-epoch high-resolution optical spectroscopy () of the emission-line object NaSt1 to test its proposed binary nature, along with long-term multiba…
SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
Calibrating Eruptive Mass Loss in Red Supergiants with Local Group Data
Shelley J. Cheng, Charlie Conroy, Jared A. Goldberg
We calibrate a physically motivated, super-Eddington eruptive mass-loss prescription for red supergiants (RSGs) using Local Group stellar populations. Building on MESA models that…
AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera
Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25
As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
