SN 1572 (Tycho Brahe’s supernova) clearly belongs to the Ia (thermonuclear) type. It was produced by the explosion of a white dwarf (WD) in a binary system. Its...
Type Ia supernovae with and without blueshifted narrow Na I D lines - how different is their structure?
In studies on intermediate- and high-resolution spectra of Type Ia supernovae (SNe Ia), some objects exhibit narrow Na I D absorptions often blueshifted with...
Understanding the extreme luminosity of DES14X2fna
We present DES14X2fna, a high-luminosity, fast-declining Type IIb supernova (SN IIb) at redshift z = 0.0453, detected by the Dark Energy Survey (DES)...
Very-high-energy gamma-ray observations of the Type Ia Supernova SN 2014J with the MAGIC telescopes
Context. In this work we present data from observations with the MAGIC telescopes of SN 2014J detected on January 21 2014, the closest Type Ia supernova since...
VRIJHK photometry of SN 2002cv (Elias-Rosa+, 2008)
The fact that another SN Ia, SN 2002bo, exploded in the same galaxy a few months before SN 2002cv, makes available pre-discovery optical and near-IR (NIR) data...
VRIJHK photometry of SN 2002cv (Elias-Rosa+, 2008)
The fact that another SN Ia, SN 2002bo, exploded in the same galaxy a few months before SN 2002cv, makes available pre-discovery optical and near-IR (NIR) data...
Here we investigate the origin of the dust mass (Mdust) observed in the Milky Way (MW) and of dust scaling relations found in a sample of local galaxies from...
XMM-Newton-discovered Fast X-ray Transients: host galaxies and limits on contemporaneous detections of optical counterparts
Extragalactic fast X-ray transients (FXTs) are a class of soft (0.3-10 keV) X-ray transients lasting a few hundred seconds to several hours. Several progenitor...
