Cosmic transients around the clock!

What do you do when you are studying an exciting transient optical phenomenon and the Sun rises, rendering further observations impossible from your observatory? Well, there is always dark sky somewhere else!

A project dubbed Global Relay of Observatories Watching Transients Happen (GROWTH), a collaboration among twelve institutions spread around the globe including OKC, has been awarded a $4.5 million over five years from NSF to perform coordinated follow-up studies of optical transients

A close look a the nearest standard candle supernova in several decades

Supernova 2014J in the nearby galaxy M82 -less than 12 million light-years away- exploded on January 14, 2014 and was the closest ”standard candle” supernova since (at least) 42 years. 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 (Goobar et al. 2014, The Astrophysical Journal Letters, 784, L12) provides important new clues into the nature of these explosions, as well as the environments where they take place. The … Continue Reading ››

Large grant for supernova research at OKC with the iPTF

It is the Knut och Alice Wallenbergs foundation that grants a 5-year long project for finding and studying supernovae. The OKC are already since the beginning of this year members of the intermediate Palomar
Transient Factory (iPTF) – a supernova search aimed at finding supernovae soon after explosion. This is a pathfinder for the next generation of this project – the Zwicky Transient Facility (ZTF). The 30 million grant from KAW will now enable OKC astronomers and physicists to play a leading role in that project.
