JWST Spectroscopy of Type Ia Supernova 2025rbs from Maximum Light to the Nebular Phase
Lindsey A. Kwok, Stéphane Blondin, Adam A. Miller +53
We present JWST observations of the Type Ia supernova (SN Ia) 2025rbs (14.5 Mpc) at +1, +23, and +84 days after B-band maximum, spanning peak light through a wavelength-depende…
JWST Observations of Calcium-Strong Transients: I. Complex Nebular He Emission in SN 2024uj
Saarah Hall, Lindsey A. Kwok, Aravind P. Ravi +29
We present the first JWST observations of a Calcium-Strong Transient (CaST), SN 2024uj, a rare class of supernovae (SNe) with observable properties that are consistent with both th…
Decoding the Early-Time Light Curves of Type Ia Supernovae. II. Population Parameters of One Thousand ZTF Supernovae
Chang Liu, Adam A. Miller, Nikhil Sarin +13
Early-time light curves of Type Ia Supernovae (SNe Ia) encode critical information about their progenitor systems. We characterize the rise of normal SNe Ia using a volume-complete…
Decoding the Early-Time Light Curves of Type Ia Supernovae. I. A Hierarchical Bayesian Framework for Demographic Inference
Chang Liu, Adam A. Miller
Light curves of Type Ia Supernovae (SNe Ia) in the days following explosion encode the diversity of progenitor systems and explosion physics. We present a hierarchical Bayesian fra…
Detection of persistent helium absorption in the 91bg-like type Ia Supernova 2022an
Ping Chen, Avishay Gal-Yam, Subo Dong +14
We present optical and near-infrared observations of the fast-declining Type Ia supernova (SN Ia) 2022an. The photometric and spectroscopic properties identify it as a standard 91b…
A Disappearing Act: Constraints From "Missing" Flares of Repeating Partial TDE Candidates
Jason T. Hinkle, Chang Liu, Adam A. Miller +6
Recurrent tidal disruption events (rTDEs) are sources that exhibit multiple TDE-like flares; many are likely powered by the recurring partial disruption of a bound star, in a repea…
JWST Spectroscopy of SN Ia 2022aaiq and 2024gy: Evidence for Enhanced Central Stable Ni Abundance and a Deflagration-to-Detonation Transition
Lindsey A. Kwok, Chang Liu, Saurabh W. Jha +48
We present optical + near-infrared (NIR) + mid-infrared (MIR) observations of the normal Type Ia supernovae (SN Ia) 2022aaiq and 2024gy in the nebular phase, continuously spanning…
StarEmbed: Benchmarking Time Series Foundation Models on Astronomical Observations of Variable Stars
Weijian Li, Hong-Yu Chen, Nabeel Rehemtulla +6
Current time series foundation model (TSFM) training corpora largely omit data with certain complexities like irregular temporal sampling. Astronomical time series of stellar fluxe…
$\texttt{HostSub_GP}$: Precise Galaxy Background Subtraction in Transient Long-slit Spectroscopy with Gaussian Processes
Chang Liu, Adam A. Miller
We present a novel host galaxy subtraction technique in long-slit spectroscopy for extragalactic transients. Unlike classic methods which generally estimate the background using a…
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…
