The type Ia supernova 2023vjh: a peculiar 1991bg-like SN with unusually faint light curves

M. Kopsacheili, L. Galbany, G. Folatelli +32

We present observations of the 1991bg-like type Ia supernova (SN) 2023vjh, associated with the elliptical galaxy MCG+04-10-013. Its light-curve shape parameters ($Δm_{15}(B)=1.89 \…

SN 2024ggi: another year, another striking Type II supernova

K. Ertini, T. A. Regna, L. Ferrari +19

SN 2024ggi is a Type II supernova that exploded in the nearby galaxy NGC 3621 at a distance of approximately 7 Mpc, making it one of the closest supernovae of the decade. This SN s…

Diversity in hydrogen-rich envelope mass of type II supernovae (II): SN 2023ixf as explosion of partially-stripped intermediate massive star

Qiliang Fang, Takashi J. Moriya, Lucía Ferrari +6

SN 2023ixf is one of the most well-observed core-collapse supernova in recent decades, yet there is inconsistency in the inferred zero-age-main-sequence (ZAMS) mass …

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…

Extrapolation of Type Ia Supernova Spectra into the Near-Infrared Using PCA

Anthony Burrow, E. Baron, Christopher R. Burns +14

We present a method of extrapolating the spectroscopic behavior of Type Ia supernovae (SNe Ia) in the near-infrared (NIR) wavelength regime up to 2.30 m using optical spectrosco…

The metamorphosis of the Type Ib SN 2019yvr: late-time interaction

Lucía Ferrari, Gastón Folatelli, Hanindyo Kuncarayakti +32

We present observational evidence of late-time interaction between the ejecta of the hydrogen-poor Type Ib supernova (SN) 2019yvr and hydrogen-rich circumstellar material (CSM), si…
