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…
Seven Years of SN 2014C: a Multi-Wavelength Synthesis of an Extraordinary Supernova
Benjamin P. Thomas, J. Craig Wheeler, Vikram V. Dwarkadas +6
SN 2014C was originally classified as a Type Ib supernova, but at phase ϕ = 127 d post-explosion strong Hα emission was observed. SN 2014C has since been observed in radio, infrare…
The First Post-Kepler Brightness Dips of KIC 8462852
Tabetha S. Boyajian, Roi Alonso, Alex Ammerman +203
We present a photometric detection of the first brightness dips of the unique variable star KIC 8462852 since the end of the Kepler space mission in 2013 May. Our regular photometr…
High-Velocity Features of Calcium and Silicon in the Spectra of Type Ia Supernovae
Jeffrey M. Silverman, Jozsef Vinko, G. H. Marion +5
"High-velocity features" (HVFs) are spectral features in Type Ia supernovae (SNe Ia) that have minima indicating significantly higher (by greater than about 6000 km/s) velocities t…
A Near-Infrared (JHK) Survey of the Vicinity of the HII region NGC 7538: Evidence for a Young Embedded Cluster
Z. Balog, S. J. Kenyon, E. A. Lada +3
We describe the results of two near infrared (K-band) imaging surveys and a three color (JHK) survey of the vicinity of NGC 7538. The limiting magnitudes are K ~ 16.5 and K ~ 17.5…
Distance of the Hypernova SN 2002ap via the Expanding Photosphere Method
J. Vinko, R. M. Blake, K. Sarneczky +10
New optical photometric and spectroscopic data of the bright hypernova SN 2002ap are presented. The obtained BVRI light curves as well as the optical spectra agree well with other…
