Light-Curve and Spectral Properties of Type II Supernovae from the ATLAS survey
K. Ertini, J. P. Anderson, G. Folatelli +22
Type II supernovae (SNe II) are the most common terminal stellar explosions in the Universe. With SNe now being detected within days after explosion, there is growing evidence that…
Nested, asymmetric H-He circumstellar shells in the Type Icn/Ibn SN 2024abvb
The INTEL Collaboration, J. P. Anderson, C. Aster +17
Interacting transients probe mass loss in the final stages of stellar evolution; however, the geometry and timing of multi-episode mass loss remain poorly constrained. SN 2024abvb…
Massive stars exploding in a He-rich circumstellar medium XII. SN 2024acyl: A fast, linearly declining Type Ibn supernova with early flash-ionisation features
Y. -Z. Cai, A. Pastorello, K. Maeda +63
We present a photometric and spectroscopic analysis of the Type Ibn supernova (SN) 2024acyl. It rises to an absolute magnitude peak of about -17.58 mag in 10.6 days, and displays a…
Long-term evolution of the SN 2009ip-like transient SN 2016cvk

The interacting transient SN 2016cvk (ASASSN-16jt) is a member of the peculiar SN 2009ip-like events. We present our follow-up data and aim to draw conclusions about the physical n…
A study in scarlet -- II. Spectroscopic properties of a sample of Intermediate Luminosity Red Transients
G. Valerin, A. Pastorello, E. Mason +65
We investigate the spectroscopic characteristics of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classical novae…

G. Valerin, A. Pastorello, A. Reguitti +57
We investigate the photometric characteristics of a sample of Intermediate Luminosity Red Transients (ILRTs), a class of elusive objects with peak luminosity between that of classi…
SN 2020pvb: a Type IIn-P supernova with a precursor outburst
Nancy Elias-Rosa, Seán J. Brennan, Stefano Benetti +37
We present photometric and spectroscopic data sets for SN 2020pvb, a Type IIn-P supernova (SN) similar to SNe 1994W, 2005cl, 2009kn and 2011ht, with a precursor outburst detected (…
The broad-lined Type-Ic supernova SN 2022xxf with extraordinary two-humped light curves
H. Kuncarayakti, J. Sollerman, L. Izzo +60
We report on our study of supernova (SN) 2022xxf based on observations obtained during the first four months of its evolution. The light curves (LCs) display two humps of similar m…
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…
Observational constraints on the optical and near-infrared emission from the neutron star-black hole binary merger S190814bv
K. Ackley, L. Amati, C. Barbieri +151
On 2019 August 14, the LIGO and Virgo interferometers detected a high-significance event labelled S190814bv. Preliminary analysis of the GW data suggests that the event was likely…
Hydrogen-rich supernovae beyond the neutrino-driven core-collapse paradigm
