Optical Spectra of Thermonuclear Supernovae in the Local and Distant Universe [PDF]

, 2005
This thesis is devoted to the study of optical spectra of thermonuclear supernovae, known as ``Type Ia'' supernovae (SN Ia). These violent stellar explosions, visible across a large fraction of the observable universe, are used to measure distances on ...

The Use of Multiwavelength Archival Observational Data for Scientific Discoveries: a Case of the Supernova Remnant Cassiopeia A

Open Astronomy, 2012
Most of the high-quality astronomical data after a proprietary period of typically one year are provided to open access, allowing researchers to complement their observations with the archival data in other wavelength bands, thus improving quality of the

Induced Gravitational Collapse, Binary-Driven Hypernovae, Long Gramma-ray Bursts and Their Connection with Short Gamma-ray Bursts

Universe, 2019
There is increasing observational evidence that short and long Gamma-ray bursts (GRBs) originate in different subclasses, each one with specific energy release, spectra, duration, etc, and all of them with binary progenitors.

Weighing Cosmological Models with SNe Ia and Gamma Ray Burst Redshift Data

Universe, 2019
Many models have been proposed to explain the intergalactic redshift using different observational data and different criteria for the goodness-of-fit of a model to the data. The purpose of this paper is to examine several suggested models using the same

Impact of Newly Measured Nuclear Reaction Rates on ²⁶Al Ejected Yields from Massive Stars

Universe
Over the last three years, the rates of all the main nuclear reactions involving the destruction and production of 26Al in stars (26Al(n, p)26Mg, 26Al(n, α)23Na, 26Al(p, γ)27Si and 25Mg(p, γ)26Al) have been re-evaluated thanks to new high-precision ...

Anisotropic pressure effect on strongly magnetized white dwarfs using quasi-local equation of state

Journal of Scientific Research in Science, 2023
This work addresses the effect of anisotropic pressure on the strong magnetized white dwarf. A quasi-local equation of state is used to formulate the anisotropic factor inside the star. We use the assumption that the magnetic field is constant and strong

Supramolecular Chiral Assemblies from Benzoselenadiazole‐Alanine‐Acylhydrazone Conjugates Enable Cardioprotection

Advanced Science, EarlyView.
The C3‐symmetric conjugate TASe, which integrates benzoselenadiazole, alanine, and acylhydrazone modules, self‐assembles into a chalcogen‐/hydrogen‐bonded porous framework in the solid state and uniform chiral nanospheres in aqueous media. These assemblies protect cardiomyocytes from doxorubicin‐induced oxidative injury by scavenging intracellular ...

Candidates for historical supernovae and their comparison against known Chinese records [PDF]

, 2003
In this MSc thesis, possible/probable supernova remnants associated with possible/probable historical supernovae are discussed and advancements in knowledge surrounding possible remnants associated with historical supernovae older than about a thousand ...

Type Ia supernovae from sub-Chandrasekhar mass white dwarfs

, 2016
We argue that detonations of sub-Chandrasekhar mass white dwarfs can lead to bright explosions with light curves and spectra similar to those of observed Type Ia supernovae.
