A massive star origin for an unusual helium-rich supernova in an elliptical galaxy

open access: yes, 2010
The unusual helium-rich (type Ib) supernova SN 2005E is distinguished from any supernova hitherto observed by its faint and rapidly fading light curve, prominent calcium lines in late-phase spectra and lack of any mark of recent star formation near the ...

Supernovae in Three-Dimension: A Link to Gamma-Ray Bursts

open access: yes, 2007
Observational consequences of a jet-driven supernova (SN) explosion model are presented. The results are compared in detail with optical observations of SN 1998bw associated with a Gamma-Ray Burst.

Constraints on Off-Axis GRB Jets in Type Ibc Supernovae From Late-Time Radio Observations

open access: yes, 2005
It has been suggested that the peculiar properties of the luminous Type Ic supernova SN 1998bw and its low-energy gamma-ray burst GRB 980425 may be understood if they originated in a standard gamma-ray burst explosion viewed far from the axis of the ...

A world-line framework for 1D Topological Conformal sigma-models

open access: yes, 2015
We use world-line methods for pseudo-supersymmetry to construct $sl(2|1)$-invariant actions for the $(2,2,0)$ chiral and ($1,2,1)$ real supermultiplets of the twisted $D$-module representations of the $sl(2|1)$ superalgebra.

Synthesis of hexa (imidazolyl) cyclotriphosphazene and its performance as curing catalyst of epoxy resin

open access: yesCailiao gongcheng, 2019
Hexa (imidazolyl) cyclotriphosphazene (HImCP) was synthesized by nucleophilic substitution reaction of hexachlorocyclotriphosphazene with imidazole. The chemical structure was characterized by FT-IR,1H-NMR, and 31P-NMR.
