A magnetar giant flare in the nearby starburst galaxy M82

Sandro Mereghetti, Michela Rigoselli, Ruben Salvaterra +32

Giant flares, short explosive events releasing up to 10 erg of energy in the gamma-ray band in less than one second, are the most spectacular manifestation of magnetars, you…

Detailed spectrophotometric analysis of the superluminous and fast evolving SN 2019neq

Achille Fiore, Stefano Benetti, Leonardo Tartaglia +24

SN 2019neq was a very fast evolving superluminous supernova. At a redshift z=0.1059, its peak absolute magnitude was -21.5+/-0.2 mag in g band. In this work, we present data and an…

SN 2022vqz: A Peculiar Subluminous Type Ia Supernova with Prominent Early Excess Emission

Gaobo Xi, Xiaofeng Wang, Gaici Li +22

We present extensive photometric and spectroscopic observations of the peculiar Type Ia supernova (SN Ia) 2022vqz. It shares many similarities with the SN 2002es-like SNe Ia, such…

Early Spectroscopy and Dense Circumstellar Medium Interaction in SN 2023ixf

K. Azalee Bostroem, Jeniveve Pearson, Manisha Shrestha +53

We present the optical spectroscopic evolution of SN~2023ixf seen in sub-night cadence spectra from 1.18 to 14 days after explosion. We identify high-ionization emission features,…

Photometry and spectroscopy of the Type Icn supernova 2021ckj: The diverse properties of the ejecta and circumstellar matter of Type Icn SNe

T. Nagao, H. Kuncarayakti, K. Maeda +20

We present photometric and spectroscopic observations of the Type Icn supernova (SN) 2021ckj. Spectral modeling of SN 2021ckj reveals that its composition is dominated by oxygen, c…

Time varying Na I D absorption in ILRTs as a probe of circumstellar material

Robert Byrne, Morgan Fraser, Yongzhi Cai +2

Intermediate-Luminosity Red Transients (ILRTs) are a class of observed transient posited to arise from the production of an electron-capture supernova from a super-asymptotic giant…

Hidden shock powering the peak of SN 2020faa

I. Salmaso, E. Cappellaro, L. Tartaglia +9

The link between the fate of the most massive stars and the resulting supernova (SN) explosion is still a matter of debate, in major part because of the ambiguity among light-curve…
