Accurate distance determination to astrophysical objects is essential for the understanding
of their intrinsic brightness and size. The distance to SN 1987A has been previously …

Observational signatures of the circumstellar material (CSM) around Type Ia supernovae
(SNe Ia) provide a unique perspective on their progenitor systems. The pre-supernova …

Over recent decades, robotic (or highly automated) searches for supernovae (SNe) have
discovered several thousand events, many of them in quite nearby galaxies (distances< 30 …

Abstract We have created Monte Carlo code Ventspils RTMC for polarized radiative transfer
modelling in an isotropic, optically inactive medium of arbitrary configuration and …

Red supergiants may experience a short-lived period of episodic mass loss rather than
steady winds before their core collapses, leading to dense circumstellar matter (CSM) close …
