Using nebular near-IR spectroscopy to measure asymmetric chemical distributions in 2003fg-like thermonuclear supernovae

J. O'Hora, C. Ashall, M. Shahbandeh +10

We present an analysis of three near-infrared (NIR; 1.0-2.4 m) spectra of the SN 2003fg-like/"super-Chandrasekhar" type Ia supernovae (SNe Ia) SN 2009dc, SN 2020hvf, and SN 2022…

Optical and near-infrared photometry of 94 type II supernovae from the Carnegie Supernova Project

J. P. Anderson, C. Contreras, M. D. Stritzinger +43

Type II supernovae (SNeII) mark the endpoint in the lives of hydrogen-rich massive stars. Their large explosion energies and luminosities allow us to measure distances, metalliciti…

On the diversity of strongly-interacting Type IIn supernovae

I. Salmaso, E. Cappellaro, L. Tartaglia +29

Massive stars experience strong mass-loss, producing a dense, H-rich circumstellar medium (CSM). After the explosion, the collision and continued interaction of the supernova (SN)…

The fast rise of the unusual Type IIL/IIb SN 2018ivc

A. Reguitti, R. Dastidar, G. Pignata +22

We present an analysis of the photometric and spectroscopic dataset of the Type II supernova (SN) 2018ivc in the nearby (10 Mpc) galaxy Messier 77. Thanks to the high cadence of th…

Eruptive mass loss less than a year before the explosion of superluminous supernovae: I. The cases of SN 2020xga and SN 2022xgc

A. Gkini, C. Fransson, R. Lunnan +47

We present photometric and spectroscopic observations of SN 2020xga and SN 2022xgc, two hydrogen-poor superluminous supernovae (SLSNe-I) at and , respectiv…

Massive stars exploding in a He-rich circumstellar medium X. Flash spectral features in the Type Ibn SN 2019cj and observations of SN 2018jmt

Z. -Y. Wang, A. Pastorello, K. Maeda +48

We present optical and near-infrared observations of two Type Ibn supernovae (SNe), SN 2018jmt and SN 2019cj. Their light curves have rise times of about 10 days, reaching an absol…

Optical Spectroscopy of Type Ia Supernovae by the Carnegie Supernova Projects I and II

N. Morrell, M. M. Phillips, G. Folatelli +57

We present the second and final release of optical spectroscopy of Type Ia Supernovae (SNe Ia) obtained during the first and second phases of the Carnegie Supernova Project (CSP-I…
