Several thousand core-collapse supernovae (CCSNe) of different flavors have been
discovered so far. However, identifying their progenitors has remained an outstanding open …

We present observations and analysis of 18 stripped-envelope supernovae observed during
2013–2018. This sample consists of five H/He-rich SNe, six H-poor/He-rich SNe, three …

ABSTRACT Analyses of Type Ia supernovae (SNe Ia) have found puzzling correlations
between their standardized luminosities and host galaxy properties: SNe Ia in high-mass …

We study the presence of optically-selected active galactic nuclei (AGNs) within a sample of
867 galaxies extracted from the extended Calar-Alto Legacy Integral Field spectroscopy …

Recent analyses have found intriguing correlations between the colour (c) of type Ia
supernovae (SNe Ia) and the size of their 'mass-step', the relationship between SN Ia host …

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 …

We present a new version of the FIT3D and Pipe3D codes, two packages to derive
properties of the stellar populations and the ionized emission lines from optical spectroscopy …

We present optical and near-infrared (NIR)(ugriYJH) photometry of host galaxies of Type Ia
supernovae (SN Ia) observed by the Carnegie Supernova Project-I. We determine host …

ABSTRACT Type Ia supernovae (SNe Ia) are used as standardizable candles to measure
cosmological distances, but differences remain in their corrected luminosities which display …

We present a sample of Type Icn supernovae (SNe Icn), a newly discovered class of
transients characterized by their interaction with H-and He-poor circumstellar material …
