Massive stars, supernovae, and kilonovae are among the most luminous radiation sources
in the Universe. Observations usually show near-to mid-infrared (NIR–MIR, λ≈ 1–5 μm) …

Context. A fundamental property determining the transient behaviour of core-collapse
supernovae (CC SNe) is the amount of radioactive 56 Ni synthesised in the explosion. Using …

Recent studies on direct imaging of Type II core-collapse supernova progenitors indicate a
possible threshold around M ZAMS∼ 16–20 M⊙, where red supergiants (RSG) with larger …

We present high-cadence photometric and spectroscopic observations of SN 2020jfo in
ultraviolet and optical/near-infrared bands starting from∼ 3 to∼ 434 d after the explosion …

We present an extensive, panchromatic photometric (UV, optical, and near-IR) and low-
resolution optical spectroscopic coverage of a Type IIP supernova SN 2018gj that occurred …

We present high-cadence UV, optical, and near-infrared data on the luminous Type II-P
supernova SN 2017gmr from hours after discovery through the first 180 days. SN 2017gmr …

Supernova remnants (SNRs) are known to accelerate cosmic rays from the detection of non-
thermal emission in radio waves, X-rays, and gamma-rays. However, the ability to accelerate …

ABSTRACT I present progenitor luminosities (L) for a sample of 112 Type II supernovae
(SNe II), computed directly from progenitor photometry and the bolometric correction …

Context. The mass of synthesised radioactive material is an important power source for all
supernova (SN) types. In addition, the difference of 56 Ni yields statistics are relevant to …

Recent observations of supernovae (SNe) just after the explosion suggest that a good
fraction of SNe have the confined circumstellar material (CSM) in the vicinity, and the pre-SN …
