International Journal of Astrobiology, 2007 AbstractThe question ‘Are supernovae important sources of dust?’ is a contentious one. Observations with the Infrared Astronomical Satellite (IRAS) and the Infrared Space Observatory (ISO) only detected very small amounts of hot dust in supernova remnants.

The Supernova – Supernova Remnant Connection [PDF]
, 2016 Many aspects of the progenitor systems, environments, and explosion dynamics of the various subtypes of supernovae are difficult to investigate at extragalactic distances where they are observed as unresolved sources. Alternatively, young supernova remnants in our own galaxy and in the Large and Small Magellanic Clouds offer opportunities to resolve ...

Galaxies, 2022 The difference from 4 to 6 σ in the Hubble constant (H0) between the values observed with the local (Cepheids and Supernovae Ia, SNe Ia) and the high-z probes (Cosmic Microwave Background obtained by the Planck data) still challenges the astrophysics and

New Hubble Space Telescope Discoveries of Type Ia Supernovae at z ≥ 1: Narrowing Constraints on the Early Behavior of Dark Energy [PDF]
, 2006 We have discovered 21 new Type Ia supernovae (SNe Ia) with the Hubble Space Telescope (HST) and have used them to trace the history of cosmic expansion over the last 10 billion yr. These objects, which include 13 spectroscopically confirmed SNe Ia at z ≥

possis: predicting spectra, light curves, and polarization for multidimensional models of supernovae and kilonovae [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We present possis, a time-dependent three-dimensional Monte Carlo code for modelling radiation transport in supernovae and kilonovae. The code incorporates wavelength- and time-dependent opacities, and predicts viewing-angle dependent spectra, light ...

Simulations of magnetized multiphase galactic disk regulated by supernovae explosions [PDF]
, 2014 What exactly controls star formation in the Galaxy remains controversial. In particular, the role of feedback and magnetic field are still partially understood.

Collapsars: Gamma-Ray Bursts and Explosions in “Failed Supernovae” [PDF]
, 1998 Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued evolution of rotating helium stars, Mα ≳ 10 M☉, in which iron-core collapse does not produce a successful outgoing shock but instead forms a black hole of 2-3 M☉. The model

Mathematical simulation of vortex motion in the astrophysical objects on the basis of the gas-dynamic model [PDF]
Компьютерные исследования и моделирование, 2018 The application of a conservative numerical method of fluxes is examined for studying the vortex structures in the massive, fast-turned compact astrophysical objects, which are in self-gravity conditions.

Evolving Dark Energy or Supernovae Systematics? [PDF]
Monthly notices of the Royal Astronomical SocietyRecent results from the Dark Energy Spectroscopic Instrument (DESI) collaboration have been interpreted as evidence for evolving dark energy. However, this interpretation is strongly dependent on which Type Ia supernova (SN) sample is combined with ...
