Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster
L. Izzo, C. Gall, N. Khetan +47
Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…
A Panchromatic View of Late-time Shock Power in the Type II Supernova 2023ixf
W. V. Jacobson-Galán, L. Dessart, C. D. Kilpatrick +39
We present multi-wavelength observations of the type II supernova (SN II) 2023ixf during its first two years of evolution. We combine ground-based optical/NIR spectroscopy with Hub…
Final Moments III: Explosion Properties and Progenitor Constraints of CSM-Interacting Type II Supernovae
W. V. Jacobson-Galán, L. Dessart, K. W. Davis +52
We present analysis of the plateau and late-time phase properties of a sample of 39 Type II supernovae (SNe II) that show narrow, transient, high-ionization emission lines (i.e., "…
A second radio flare from the tidal disruption event AT2020vwl: a delayed outflow ejection?
A. J. Goodwin, A. Mummery, T. Laskar +12
We present the discovery of a second radio flare from the tidal disruption event (TDE) AT2020vwl via long-term monitoring radio observations. Late-time radio flares from TDEs are b…
Quasi-periodic X-ray eruptions years after a nearby tidal disruption event
M. Nicholl, D. R. Pasham, A. Mummery +61
Quasi-periodic Eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of galaxies, repeating on timescales of hours to weeks. The mechanism behind these rare systems i…
Constraints on the Sub-pc Environment of the Nearby Type Iax SN 2014dt from Deep X-ray and Radio Observations
Candice M. Stauffer, Raffaella Margutti, Justin D. Linford +8
We present X-ray and radio observations of what may be the closest type Iax supernova (SN) to date, SN 2014dt (d=12.3-19.3 Mpc) and provide tight constraints on the radio and X-ray…
Star formation and morphological properties of galaxies in the Pan-STARRS survey- I. A machine learning approach to galaxy and supernova classification
A. Baldeschi, A. Miller, M. Stroh +2
We present a classification of galaxies in the Pan-STARRS1 (PS1) 3 survey based on their recent star formation history and morphology. Specifically, we train and test two Random…
ELT Contributions to Tidal Disruption Events
J. Craig Wheeler, Rafaella Margutti, Ryan Chornock +3
An ELT system with its large aperture and sensitive optical and near infrared imager spectrographs will make major contributions to the study of stars ripped apart by supermassive…
ELT Contributions to The First Explosions
J. Craig Wheeler, József Vinkó, Rafaella Margutti +3
The large aperture and sensitive optical and near infrared imager spectrographs will enable an ELT system to observe some supernovae at large distances, deep into cosmological hist…
