Wild behaviour near the finish line: the Type Ibn SN 2020able and its stratified environment

L. Tartaglia, E. Cappellaro, G. Valerin +29

We present spectrophotometric observations of the Type Ibn supernova SN~2020able, along with a comprehensive analysis and modelling of its evolution. The transient occurred in SDSS…

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…

SN 2017ati: A luminous type IIb explosion from a massive progenitor

Z. -H. Peng, S. Benetti, Y. -Z. Cai +21

We present optical photometric and spectroscopic observations of the Type~IIb supernova (SN)~2017ati. It reached the maximum light at about 27~d after the explosion and the light c…

SN 2022ngb: A faint, slowly evolving Type IIb supernova with a low-mass envelope

J. -W. Zhao, S. Benetti, Y. -Z. Cai +35

An extensive photometric and spectroscopic follow-up campaign of the Type IIb SN 2022ngb is presented in the article. Through detailed modeling of this dataset, we aim to constrain…

Normal or transitional? The evolution and properties of two type Ia supernovae in the Virgo cluster

L. Izzo, C. Gall, N. Khetan +47

Type Ia supernovae (SNe Ia) are among the most precise cosmological distance indicators used to study the expansion history of the Universe. The vast increase of SN Ia data due to…

EP250207b is not a collapsar fast X-ray transient. Is it due to a compact object merger?

P. G. Jonker, A. J. Levan, Xing Liu +41

Fast X-ray Transients (FXTs) are short-lived extra-galactic X-ray sources. Recent progress through multi-wavelength follow-up of Einstein Probe discovered FXTs has shown that sever…
