An extremely fast fading population II dwarf nova candidate: caught spectroscopically on the rise
Natasha Van Bemmel, Jielai Zhang, Jeff Cooke +14
We present AT2022kak, a rapidly evolving optical transient discovered by the KiloNova and Transients Program (KNTraP). This interesting burst exhibited extremely fast evolution, wi…
Spectral Diversity in Type Ibn Supernovae and the Large Host Offset of SN2024acyl
Yize Dong, V. Ashley Villar, Anya Nugent +35
In this paper, we first present observations of SN~2024acyl, a normal Type Ibn supernova with a large projected offset (35~kpc) from its host galaxy. The low star-formation r…
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…
Characterising the Standardisation Properties of Type Ia Supernovae in the z band with Hierarchical Bayesian Modelling
Erin E. Hayes, Suhail Dhawan, Kaisey S. Mandel +21
Type Ia supernovae (SNe Ia) are standardisable candles: their peak magnitudes can be corrected for correlations between light curve properties and their luminosities to precisely e…
Early and Extensive Ultraviolet Through Near Infrared Observations of the Intermediate-Luminosity Type Iax Supernovae 2024pxl
W. B. Hoogendam, C. Ashall, D. O. Jones +12
We present ultraviolet (UV) through near-infrared (NIR) photometric and spectroscopic observations of the nearby SN 2024pxl, the third Type Ia supernova (SN Ia) in NGC 6384. SN 202…
JWST and Ground-based Observations of the Type Iax Supernovae SN 2024pxl and SN 2024vjm: Evidence for Weak Deflagration Explosions
Lindsey A. Kwok, Mridweeka Singh, Saurabh W. Jha +89
We present panchromatic optical near-infrared (NIR) mid-infrared (MIR) observations of the intermediate-luminosity Type Iax supernova (SN Iax) 2024pxl and the extremely low…
Photometry and Spectroscopy of SN 2024pxl: A Luminosity Link Among Type Iax Supernovae
Mridweeka Singh, Lindsey A. Kwok, Saurabh W. Jha +90
We present extensive ultraviolet to optical photometric and optical to near-infrared (NIR) spectroscopic follow-up observations of the nearby intermediate-luminosity ($M_V = -16.81…
The Ultraviolet Spectra of 2003fg-like Type Ia Supernovae
Snehasish Bhattacharjee, Yen-Chen Pan, Hao-Yu Miao +5
2003fg-like Type Ia supernovae (03fg-like SNe Ia) are rare subtype of SNe Ia, photometrically characterized by broader optical light curves and bluer ultraviolet (UV) colors compar…
A Large-Scale Search for Photometrically Variable AGNs in Dwarf Galaxies Using the Young Supernova Experiment
Alexander Messick, Vivienne Baldassare, David O. Jones +12
We conduct an analysis of over 60,000 dwarf galaxies (7<=log(M_*/M_\odot)<=10) in search of photometric variability indicative of active galactic nuclei (AGNs). Using data from the…
The BTSbot-nearby discovery of SN 2024jlf: rapid, autonomous follow-up probes interaction in an 18.5 Mpc Type IIP supernova
Nabeel Rehemtulla, W. V. Jacobson-Galán, Avinash Singh +27
We present observations of the Type IIP supernova (SN) 2024jlf, including spectroscopy beginning just 0.7 days (17 hours) after first light. Rapid follow-up was enabled by th…
