A group of scientists managed to open 1824 candidate supernovae of various types in 10 months of observations. This allows you to make new discoveries in observational cosmology and better understand the processes that lead to the supernova explosions.
As reported in the journal Publications of the Astronomical Society of Japan, a team of astronomers from Japan, Taiwan and the United States published the results of a five-year program the HSC-SSP (Subaru HSC Strategic survey Program) conducted by the 8.2-m telescope “Subaru”.
The telescope is equipped with a 870-megapixel digital camera Hyper Suprime-Cam wide field of view. The observations were carried out from November 2016 to April 2017, for the work was selected area of the sky used for exploring the COSMOS. In the future, was conducted spectroscopic studies of newly discovered objects with the number of ground-based telescopes.
Photos of possible candidates in supernovae
The work resulted in the identification of 1824 candidates in a supernova ten months of observations.
What is supernova or supernova? This is a star that suddenly increases its luminosity by billions of times, and sometimes more. At the peak of the supernova emits as much light as it emit billions of stars together. This is the most luminous of all known stars, their luminosity is comparable to the brightness of a whole galaxy, and sometimes even exceeds it.
For comparison, the Hubble telescope took about ten years to discover fifty supernova whose light went to the Ground more than 8 billion years.
The review has become one of the most profound of the Supervisory programs of a large area of sky held today, and gives you the opportunity to study not only the supernovae type Ia and SLSN, but and type II, variable stars and active galactic nuclei.
