Characterization of type Ibn SNe

D. Farias, C. Gall, V. A. Villar +29

Type Ibn supernovae (SNe) are characterized by narrow helium (He I) lines from photons produced by the unshocked circumstellar material (CSM). About 80 SNe Ibn have been discovered…

The New Status Qvo? SN 2021qvo is Another 2003fg-like Type Ia Supernova with a Rising Light-Curve Bump

I. A. Abreu Paniagua, W. B. Hoogendam, D. O. Jones +24

In recent years, multiple Type Ia supernovae (SNe Ia) have been observed with ''bumps'' in their rising light curves shortly after explosion. Here, we present SN 2021qvo: a SN Ia t…

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., "…

Discovery of a likely Type II SN at =3.6 with JWST

D. A. Coulter, J. D. R. Pierel, C. DeCoursey +30

Transient astronomy in the early, high-redshift (z > 3) Universe is an unexplored regime that offers the possibility of probing the first stars and the Epoch of Reionization. Durin…

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…

Properties of high-redshift Type II supernovae discovered by the JADES transient survey

Takashi J. Moriya, David A. Coulter, Christa DeCoursey +23

In this work we estimate the explosion and progenitor properties of six Type II supernovae (SNe) at 0.675 <= z <= 3.61 discovered by the James Webb Space Telescope (JWST) Advanced…
