SN 2021aaev: a Hydrogen-Rich Superluminous Supernova with Early Flash and Long-Lived Circumstellar Interaction in an Unusual Host Environment
Yang Hu, Ragnhild Lunnan, Priscila J. Pessi +25
We present photometric and spectroscopic observations of SN\,2021aaev, a hydrogen-rich, superluminous supernova with persistent (at least days) narrow Balmer lines (SLSN-…
Unveiling the nature of SN 2022jli: The first double-peaked stripped-envelope supernova showing periodic undulations and dust emission at late times
Régis Cartier, Carlos Contreras, Maximilian Stritzinger +6
We present optical and infrared observations from maximum light until around +800 days of supernova (SN) 2022jli, a peculiar stripped-envelope (SE) SN showing two maxima, each one…
Discovery and Extensive Follow-Up of SN 2024ggi, a nearby type IIP supernova in NGC 3621
Ting-Wan Chen, Sheng Yang, Shubham Srivastav +45
We present the discovery and early observations of the nearby Type II supernova (SN) 2024ggi in NGC 3621 at 6.64 +/- 0.3 Mpc. The SN was caught 5.8 (+1.9 -2.9) hours after its expl…
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…
Strong Carbon Features and a Red Early Color in the Underluminous Type Ia SN 2022xkq
Jeniveve Pearson, David J. Sand, Peter Lundqvist +85
We present optical, infrared, ultraviolet, and radio observations of SN 2022xkq, an underluminous fast-declining type Ia supernova (SN Ia) in NGC 1784 ( Mpc),…
The carbon-rich type Ic supernova 2016adj in the iconic dust lane of Centaurus A: signatures of interaction with circumstellar hydrogen?
Maximilian D. Stritzinger, Eddie Baron, Francesco Taddia +24
We present a comprehensive data set of supernova (SN) 2016adj located within the central dust lane of Centaurus A. SN 2016adj is significantly reddened and after correcting the pea…
Carnegie Supernova Project-II: Near-infrared Spectroscopic Diversity of Type II Supernovae
S. Davis, E. Y. Hsiao, C. Ashall +24
We present near-infrared (NIR) spectra of Type II supernovae (SNe II) from the Carnegie Supernova Project-II (CSP-II), the largest such dataset published to date. We iden…
Investigating the diversity of supernovae type Iax: A MUSE and NOT spectroscopic study of their environments
J. D. Lyman, F. Taddia, M. D. Stritzinger +9
SN 2002cx-like Type Ia supernovae (also known as SNe Iax) represent one of the most numerous peculiar SN classes. They differ from normal SNe Ia by having fainter peak magnitudes,…
