The theory and numerical modelling of radiation processes and radiative transfer play a key
role in astrophysics: they provide the link between the physical properties of an object and …

We present the ATLAS discovery and initial analysis of the first 18 days of the unusual
transient event, ATLAS18qqn/AT2018cow. It is characterized by a high peak luminosity (∼ …

The kilonova (KN) associated with the binary neutron star (BNS) merger GW170817 is the
only known electromagnetic counterpart to a gravitational wave source. Here we produce a …

Recent studies have shown how the distribution of 56 Ni within the ejected material of type
Ia supernovae can have profound consequences on the observed light curves. Observations …

An excess of flux (ie a bump) in the early light curves of type Ia supernovae has been
observed in a handful of cases. Multiple scenarios have been proposed to explain this …

The detonation of a helium shell on top of a carbon–oxygen white dwarf has been argued as
a potential explosion mechanism for Type Ia supernovae (SNe Ia). The ash produced during …

ABSTRACT Investigations of some Type Iax supernovae (SNe Iax) have led to the
suggestion that their ejecta must be layered to some degree. Such an ejecta structure has …

We present early-time (t<+ 50 d) observations of SN 2019muj (= ASASSN-19tr), one of the
best-observed members of the peculiar SN Iax class. Ultraviolet and optical photometric and …

We present the discovery and optical follow-up of the faintest supernova-like transient
known. The event (SN 2019gsc) was discovered in a star-forming host at 53 Mpc by ATLAS …

We present optical observations and analysis of the bright type Iax supernova SN 2020udy
hosted by NGC 0812. The evolution of the light curve of SN 2020udy is similar to that of …
