An impressive coordinated observational effort orchestrated by the intermediate Palomar Transient Factory (iPTF) team and led by Ariel Goobar from the Oskar Klein Centre at Stockholm University provides important new clues into the nature of these explosions, as well as the environments where they take place.
Then, in the late 2000s, these survey programs were trumped by the Palomar Transient Factory (PTF), which uses the 48-inch Schmidt telescope at Palomar, and the 1.8-meter Panoramic Survey Telescope & Rapid Response System (Pan-STARRS1) instrument in Hawaii.
This was subsequently confirmed by a number of observers including the Palomar Transient Factory (Silverman et al., ATEL 3398).
With large sky surveys--such as the Palomar Transient Factory that Quimby's team used- finding thousands of supernovas, it's no surprise that astronomers have discovered some brilliant oddballs, says theorist Stan Woosley of the University of California, Santa Cruz.
Work is continuing with around 60 Type II SN, spotted by the Palomar Transient Factory survey at Palomar Observatory in California, to get the method to work at greater distances and let them probe further back in the Universe's history.
Surveys that watch the skies for flashes of light like supernovae -- surveys such as the Palomar Transient Factory (PTF), led by Caltech -- are well suited to discover these unique events, he says.
New research began last August, when the automatic telescopes at the Palomar Transient Factory (PTF) in California that search for signs of developing supernova spotted one just a half a day into the explosion process.
The Palomar Transient Factory skypatrol project discovered the stellar explosion on August 24th when it was still only magnitude 17.2.
The Palomar Transient Factory (PTF), for example, has identified more than 900 explosions in its first two years alone.
