The nearby Type II supernova 2024ggi beyond 600 days: circumstellar interaction and dust formation
L. Ferrari, G. Folatelli, C. P. Gutiérrez +16
The Type II SN 2024ggi is one of the nearest core-collapse SNe to have exploded in recent decades. Its proximity has enabled extensive multiwavelength monitoring from early times t…
Optical and near-infrared nebular-phase spectroscopy of SN 2024ggi: constraints on the structure of the inner ejecta, progenitor mass, and dust
Emilio Hueichapán, Régis Cartier, Jose L. Prieto +7
We present optical and near-infrared (NIR) spectroscopic observations of the nearby Type II supernova SN\,2024ggi from 250 and 581 days after the explosion. Comparing the evolution…
ASASSN-13dn: A Luminous and Double-Peaked Type II Supernova
E. Hueichapán, J. L. Prieto, R. Cartier +5
We present observations of ASASSN-13dn, one of the first supernovae discovered by ASAS-SN, and a new member of the rare group of Luminous Type II Supernovae (LSNe II). It was disco…
A possible surviving companion of the SN Ia in the Galactic SNR G272.2-3.2
Pilar Ruiz-Lapuente, Jonay I. González Hernández, Régis Cartier +4
We use the {\it Gaia} EDR3 to explore the Galactic supernova remnant SNR G272.2-3.2, produced by the explosion of a Type Ia supernova (SNIa), about 7,500 years ago, to search for a…
Core-collapse supernova subtypes in luminous infrared galaxies
E. Kankare, A. Efstathiou, R. Kotak +34
We present the discovery and follow-up observations of two CCSNe that occurred in the luminous infrared galaxy (LIRG), NGC3256. The first, SN2018ec, was discovered using the ESO HA…
Photometric and spectroscopic evolution of the interacting transient AT 2016jbu (Gaia16cfr)
S. J. Brennan, M. Fraser, J. Johansson +68
We present the results from a high cadence, multi-wavelength observation campaign of AT 2016jbu (aka Gaia16cfr), an interacting transient. This dataset complements the current lite…
Near-Infrared and Optical Observations of Type Ic SN2020oi and broad-lined Ic SN2020bvc: Carbon Monoxide, Dust and High-Velocity Supernova Ejecta
J. Rho, A. Evans, T. R. Geballe +33
We present near-infrared and optical observations of the Type Ic Supernova (SN) 2020oi in the galaxy M100 and the broad-lined Type Ic SN2020bvc in UGC 9379, using Gemini, LCO, SOAR…
The Evolution of Luminous Red Nova AT 2017jfs in NGC 4470
A. Pastorello, T. -W. Chen, Y. -Z. Cai +43
We present the results of our photometric and spectroscopic follow-up of the intermediate-luminosity optical transient AT 2017jfs. At peak, the object reaches an absolute magnitude…
On the Ca-strong 1991bg-like type Ia supernova 2016hnk: evidence for a Chandrasekhar-mass explosion
Lluís Galbany, Chris Ashall, Peter Hoeflich +46
We present a comprehensive dataset of optical and near-infrared photometry and spectroscopy of type~Ia supernova (SN) 2016hnk, combined with integral field spectroscopy (IFS) of it…
Signatures of Circumstellar Interaction in the Type IIL Supernova ASASSN-15oz
K. Azalee Bostroem, Stefano Valenti, Assaf Horesh +27
Hydrogen-rich, core-collapse supernovae are typically divided into four classes: IIP, IIL, IIn, and IIb. In general, interaction with circumstellar material is only considered for…

Supernova (SN) 2018oh (ASASSN-18bt) is the first spectroscopically-confirmed type Ia supernova (SN Ia) observed in the field. The data revealed an excess emission…
SN 2017dio: a type-Ic supernova exploding in a hydrogen-rich circumstellar medium
Hanindyo Kuncarayakti, Keiichi Maeda, Christopher J. Ashall +42
SN 2017dio shows both spectral characteristics of a type-Ic supernova (SN) and signs of a hydrogen-rich circumstellar medium (CSM). Prominent, narrow emission lines of H and He are…
