SN 2024iss: A Multi-Wavelength Exposé of a Type IIb Supernova with an Early-Time Ultraviolet Spectrum and Shock Breakout Constraints
Rujula Yete, Wynn Jacobson-Galan, Ferdinand Ferdinand +49
We present multi-wavelength observations and a comprehensive analysis of the nearby (D14 Mpc) Type IIb supernova (SN IIb) 2024iss. Observations of SN2024iss include an early…
AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera
Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25
As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
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…
The compact object and innermost ejecta of SN 1987A
J. Larsson, C. Fransson, P. J. Kavanagh +12
The first JWST observations of SN 1987A provided clear evidence that a compact object is ionizing the innermost ejecta. Here we analyze a second epoch of JWST NIRSpec and MIRI/MRS…
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…
An Updated Detection Pipeline for Precursor Emission in Type II Supernova 2020tlf
Wynn Jacobson-Galán, Sebastian Gonzalez, Shreyas Patel +34
We present a new photometric pipeline for the detection of pre-supernova (pre-SN) emission in the Young Supernova Experiment (YSE) sky survey. The method described is applied to SN…
AT 2020nov: Evidence for Disk Reprocessing in a Rare Tidal Disruption Event
Nicholas Earl, K. Decker French, Enrico Ramirez-Ruiz +23
We present a detailed analysis of AT 2020nov, a tidal disruption event (TDE) in the center of its host galaxy, located at a redshift of . AT 2020nov exhibits unique feat…
LensWatch. II. Improved Photometry and Time-delay Constraints on the Strongly Lensed Type Ia Supernova 2022qmx ("SN Zwicky") with HST Template Observations
Conor Larison, Justin D. R. Pierel, Max J. B. Newman +34
Strongly lensed supernovae (SNe) are a rare class of transient that can offer tight cosmological constraints that are complementary to methods from other astronomical events. We pr…
SN2023ixf in Messier 101: the twilight years of the progenitor as seen by Pan-STARRS
Conor L. Ransome, V. Ashley Villar, Anna Tartaglia +28
The nearby type II supernova, SN2023ixf in M101 exhibits signatures of early-time interaction with circumstellar material in the first week post-explosion. This material may be the…
SN 2022oqm: A Bright and Multi-peaked Calcium-rich Transient
S. Karthik Yadavalli, V. Ashley Villar, Luca Izzo +60
We present the photometric and spectroscopic evolution of SN 2022oqm, a nearby multi-peaked hydrogen- and helium-weak calcium-rich transient (CaRT). SN 2022oqm was detected 13.1 kp…
Mixture Models for Photometric Redshifts
Z. Ansari, A. Agnello, C. Gall
Determining photometric redshifts to high accuracy is paramount to measure distances in wide-field cosmological experiments. With only photometric information at hand, photo-zs are…
SN 2016coi (ASASSN-16fp): an energetic H-stripped core-collapse supernova from a massive stellar progenitor with large mass loss
G. Terreran, R. Margutti, D. Bersier +25
We present comprehensive observations and analysis of the energetic H-stripped SN 2016coi (a.k.a. ASASSN-16fp), spanning the -ray through optical and radio wavelengths, acquired…
