Physics with Supernovae

, 2020
Core-collapse supernovae (SNe) are powerful neutrino sources and as such important targets for the growing array of neutrino observatories. We review the current status of SN theory and the expected characteristics of the neutrino signal. After recalling

Type Ia Supernovae from First-generation Stars

The Astrophysical Journal
Abstract Type Ia supernovae (SNe Ia) discovered at redshift z ≲ 2.5 are presumed to be produced from Population I/II stars. In this work, we investigate the production of SNe Ia from Population III binaries in the cosmological framework.

Optical light curves of the type Ia supernovae SN 1990N and SN 1991T [PDF]

, 1998
Artículo de publicación ISIWe present UBV RI light curves for the bright Type Ia supernovae SN 1990N in NGC 4639 and SN 1991T in NGC 4527, based on photometry gathered in the course of the Cala n/Tololo supernova program.

Examining the Properties of Low-Luminosity Hosts of Type Ia Supernovae from ASAS-SN

, 2022
We present a spectroscopic analysis of 44 low-luminosity host galaxies of Type Ia supernovae (SNe Ia) detected by the All-Sky Automated Survey for Supernovae (ASAS-SN), using the emission lines to measure metallicities and star formation rates.

Generation of Seed Magnetic Fields in Primordial Supernova Remnants

, 2009
Origin of the magnetic field ubiquitous in the Universe is studied based on the Biermann mechanism, which is expected to work in the non-barotropic region. We perform a series of two-dimensional MHD simulations of the first generation supernova remnant (SNR) expanding in the inhomogeneous interstellar matter (ISM) and study the Biermann mechanism ...

Extending Supernova Spectral Templates for Next-generation Space Telescope Observations

Publications of the Astronomical Society of the Pacific, 2018
Empirical models of supernova (SN) spectral energy distributions (SEDs) are widely used for SN survey simulations and photometric classifications. The existing library of SED models has excellent optical templates but limited, poorly constrained coverage of ultraviolet (UV) and infrared (IR) wavelengths.

Supernovae and cosmology with future European facilities.

, 2013
Prospects for future supernova surveys are discussed, focusing on the European Space Agency's Euclid mission and the European Extremely Large Telescope (E-ELT), both expected to be in operation around the turn of the decade.
