Significance of neutrino-neutrino interaction in neutrino oscillation in core-collapse supernova

Bibechana, 2014
We study the possibility of neutrino-neutrino interaction inside the neutrino core of supernova (ρ ≥ 1010 g/cc) and outside the neutrinosphere. The angular dependence of the neutrino-neutrino interaction Hamiltonian causes multi-angle effects that can ...

Ghost particles in the universe: Neutrinos in astrophysics and cosmology

Mètode Science Studies Journal: Annual Review, 2017
  Neutrinos are nearly massless and very difficult to detect because they interact so very weakly. Sixty years after seeing the first of these «ghost particles» we know a lot about their properties.

Evaluation of Sealing Strength in Multilayer LLDPE Packaging for Impact-Resistant Rice Pouches

Jurnal Kimia Sains dan Aplikasi
In this study, we evaluate the mechanical integrity, thermal stability, and impact resilience of three different laminated polymer materials—PA/LLDPE, MDO-PE/LLDPE, and BOPE/LLDPE—to assess their suitability for rice packaging applications.

QUÍMICA ESTELAR E ESTRELAS APOCALÍPTICAS: ESTUDO COMPARATIVO

Colloquium Exactarum, 2012
All atoms existing in the Universe, except Hydrogen (H) and helium (He), arise from processes occurring in stars and their evolution. The stars transmute the H and He in other heavier elements through nuclear fusion and its process rolling, filling and ...

Testing homogeneity with galaxy number counts : light-cone metric and general low-redshift expansion for a central observer in a matter dominated isotropic universe without cosmological constant

, 2009
As an alternative to dark energy it has been suggested that we may be at the center of an inhomogeneous isotropic universe described by a Lemaitre-Tolman-Bondi (LTB) solution of Einstein's field equations.

The Status of Multi-Dimensional Core-Collapse Supernova Models [PDF]

Publications Astronomical Society of Australia, 2016
Models of neutrino-driven core-collapse supernova explosions have matured considerably in recent years. Explosions of low-mass progenitors can routinely be simulated in 1D, 2D, and 3D.

The high energy X-ray probe (HEX-P): science overview

Frontiers in Astronomy and Space Sciences
To answer NASA’s call for a sensitive X-ray observatory in the 2030s, we present the High Energy X-ray Probe (HEX-P) mission concept. HEX-P is designed to provide the required capabilities to explore current scientific questions and make new discoveries ...

First Observations of SN 1604 (Kepler’s Supernova)

Universe, 2021
A supernova close enough to the Earth is a spectacular event: it can appear as a “new star” as luminous as Venus, or even more, visible for several days.

Progenitors of Recombining Supernova Remnants

, 2012
Usual supernova remnants have either ionizing plasma or plasma in collisional ionization equilibrium, i.e., the ionization temperature is lower than or equal to the electron temperature.
