Spectral modeling of type II supernovae. I. Dilution factors [PDF]
We present substantial extensions to the Monte Carlo radiative transfer code TARDIS to perform spectral synthesis for type II supernovae. By incorporating a non-LTE ionization and excitation treatment for hydrogen, a full account of free–free and bound ...

Long Plateau Doth So: How Internal Heating Sources Affect Hydrogen-rich Supernova Light Curves
Some hydrogen-rich core-collapse supernovae (SNeIIP) exhibit evidence of a sustained energy source powering their light curves, resulting in a brighter and/or longer-lasting hydrogen recombination plateau phase.

ABSTRACT This paper examines Israel's destruction and ‘humanitarianisation’ of Palestinian health systems, arguing that this should be understood as an instance of ‘necropolitics,’ as conceived by Achille Mbembe. We review the extensive, long‐term destruction of health systems in Palestine before 7 October 2023 and the catastrophic acceleration of that

Supernovae and their host galaxies – II. The relative frequencies of supernovae types in spirals [PDF]
We present an analysis of the relative frequencies of different supernova (SN) types in spirals with various morphologies and in barred or unbarred galaxies. We use a well-defined and homogeneous sample of spiral host galaxies of 692 SNe from the Sloan Digital Sky Survey in different stages of galaxy-galaxy interaction and activity classes of nucleus ...

Positron survival in type II supernovae [PDF]
In this work I investigate the possibility of Type II supernovae being the origin for positrons producing observed annihilation radiation observed toward the Galactic center.

X-ray emission from radiative shocks in type II supernovae [PDF]
The X-ray emission from the circumstellar interaction in type II supernovae with a dense circumstellar medium is calculated. In type IIL and type IIn supernovae, mass loss rates are generally high enough for the region behind the reverse shock to be ...

SN 2019tua: A Type IIb Supernova with Multiple Bumps in the Light Curves
We present photometric and spectroscopic observations and analysis of the Type IIb supernova (SN) SN 2019tua, which exhibits multiple bumps in its declining light curves between 40 and 65 days after discovery.

Whole Genome Assembly and Annotation of Two Invasive Sitona Species
ABSTRACT Weevils are a highly diversified taxon, comprising about 70,000 described species, including many of high economic importance. Here, we present whole genome assemblies and annotations of two Sitona species (Coleoptera: Curculionidae: Entiminae).

THE STANDARDIZED CANDLE METHOD FOR TYPE II PLATEAU SUPERNOVAE [PDF]
In this paper we study the "standardized candle method" using a sample of 37 nearby (z<0.06) Type II plateau supernovae having BVRI photometry and optical spectroscopy. An analytic procedure is implemented to fit light curves, color curves, and velocity curves. We find that the V-I color toward the end of the plateau can be used to estimate the host-
