Tomography analysis of the intermediate-luminosity Type Iax SN 2024pxl
Barnabás Barna, Mridweeka Singh, Lindsey A. Kwok +90
We present an abundance tomography analysis of SN 2024pxl, an intermediate luminosity Type Iax supernova ( mag), with the most-detailed follow-up in the Type…
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 \…
Decoding the Early-Time Light Curves of Type Ia Supernovae. II. Population Parameters of One Thousand ZTF Supernovae
Chang Liu, Adam A. Miller, Nikhil Sarin +13
Early-time light curves of Type Ia Supernovae (SNe Ia) encode critical information about their progenitor systems. We characterize the rise of normal SNe Ia using a volume-complete…
The flash-ionised SN Ibn 2025kzr: H-free CSM formed during a precursor outburst 55 days prior to explosion
S. de Wet, G. Leloudas, D. A. H. Buckley +33
Type Ibn supernovae (SNe) are a class of interacting SNe characterised by narrow helium lines in their spectra. We present an extensive observational dataset of the Type Ibn SN 202…
Probing a new subclass of llGRB-SN transients: Insights from EP250304a and its associated supernova
L. Cotter, A. Martin-Carrillo, R. A. J. Eyles-Ferris +62
With the advent of the Einstein Probe (EP) mission, we are entering a new era in the study of gamma-ray bursts (GRBs), enabling the detection of faint, low-luminosity transients th…
The extremely low-luminosity Type Iax SNe 2022ywf and 2023zgx
Barnabás Barna, Dominik Bánhidi, Tamás Szalai +25
We present the optical follow-up of SNe 2022ywf and 2023zgx, two examples from the Iax subclass of thermonuclear supernova (SN) events. With peak absolute magnitudes of $M_\mathrm{…
Photometric classification of supernovae detected by the Zwicky Transient Facility using noise augmentation
A. Townsend, J. Nordin, M. Kowalski +27
Modern time-domain surveys, such as the Zwicky Transient Facility (ZTF), detect far more extragalactic transients than can be spectroscopically classified. Photometric classificati…
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…
The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases
A. Fiore, A. Kozyreva, L. Yan +40
Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…
Study of the anisotropy of cosmic expansion on ZTF type Iasupernovae simulations
C. Barjou-Delayre, P. Rosnet, C. Ravoux +29
The cosmological principle assumes the isotropy of the Universe at large scales. It is a foundational assumption in the CDM model, which is the current standard model of cosmolo…
