Of the supernovae recorded in history, there are at least two for which re-explosions have been documented. One is the supernova which appeared on 1006 May 1 (Northern Song Dynasty, Reign Jingde , Year 3) in the asterism Qiguan , south of the lunar mansion Di , which, after 10 ...
Another guest star, now known asSN 1054, was clearly recorded in Chinese records in July 1054. The remnant of that star is one of the most famous and best-studied objects in the sky, called theCrab Nebula(Figure 1 of Pulsars and the Discovery of Neutron Stars). It is a marvelously comp...

Observation History Hipparchus' interest in the fixed stars may have been inspired by the observation of a supernova (according to Pliny). The earliest recorded supernova, SN 185, was viewed by Chinese astronomers in 185 AD. The brightest recorded supernova was the SN 1006, which was described...
It follows from(11.12)that supernova explosions may result in the generation of cosmic rays withE≲ 1017eV and if it is a question ofheavy nucleithen withE≲ 1019eV. Since the highest energy recorded in cosmic radiation isEmax∼ 1019to 1020eV (only a few particles with energies greater ...
spectra10,11. None of these VMP stars exhibits such low α-element abundances. The remarkably low α elements to iron ratios, along with the unusual absence of sodium and barium, indicate that J1010+2358 may have recorded a chemical enrichment history completely different from those of most ...

t really in a rush I decided to go seek an outreach program during the Summer time. And they always perform this program during Spring-Summer time. And that’s where I found the nearest place they will have it in Rochester New York. Oh, not to mention here in that place is where I...
In this review, after an overview of the current SN taxonomy (Sect.2) and the progresses of SN surveys (Sect.3), I will focus on the use of SNe as cosmological probes. In particular, I will describe the use of SNe as tracers of the cosmic star formation history (Sect.4), their ca...
