SN 2019hnl: A Type IIP Supernova with a Partially Stripped, Low Mass Progenitor
Aidan Martas, Stefano Valenti, Aravind P. Ravi +17
We present optical photometry and spectroscopy of SN 2019hnl. Discovered within ~26 hr of explosion by the ATLAS survey, SN 2019hnl is a typical Type IIP supernova with a peak abso…
Late-time Hubble Space Telescope Ultraviolet Spectra of SN 2023ixf and SN 2024ggi Show Ongoing Interaction with Circumstellar Material
K. Azalee Bostroem, Stefano Valenti, David J. Sand +31
We present far- and near-ultraviolet (UV) spectra of the Type II supernovae (SNe) SN~2023ixf from days 199 to 722 and SN~2024ggi at days 41 and 232. Both supernovae show broad, blu…
Dangerous Questions in Astronomy Education
Michael Fitzgerald, Rachel Freed, Dan Reichart +63
As astronomy enters an era defined by global telescope networks, petabyte-scale surveys, and powerful computational tools, the longstanding goals of astronomy education, particular…
Mid-Infrared Dust Evolution and Late-time Circumstellar Medium Interaction in SN 2017eaw
Jeniveve Pearson, Bhagya Subrayan, David J. Sand +24
We present JWST/MIRI and complementary ground-based near-infrared observations of the Type II SN 2017eaw taken 6 years post-explosion. SN 2017eaw is still detected out to 25 m a…
Early Shock-Cooling Observations and Progenitor Constraints of Type IIb SN 2024uwq
Bhagya M. Subrayan, David J. Sand, K. Azalee Bostroem +26
We present early multi-wavelength photometric and spectroscopic observations of the Type IIb supernova SN 2024uwq, capturing its shock-cooling emission phase and double-peaked ligh…
