After eight years of existence, the Oskar Klein Centre of cosmoparticle physics ranks among the most dynamic and successful European research centres in the field. We are proud for having hosted outstanding postdocs and recruited world leading researchers.
Today, a new chapter in the OKC success story is about to unfold: it is time for me to pass on the baton to Hiranya Peiris, as she starts her journey as the new director of the centre.
As we close the book on 2015 we can again look back at a year of exciting science and great accomplishments by members of the Oskar Klein Centre for Cosmoparticle Physics.
As in previous years, OKCers feature very prominently in the list of the most cited astrophysics and cosmology papers led by Swedish scientists published during the year. The list was compiled by Robert Cumming in populärastronomi
and appears in today’s issue.
In fact, half of top-10 2015 publications originate in our centre, starting … Continue Reading ››
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
Discovering exploding stars, supernovae, within hours from explosion opens new windows to study their nature. Last year, our group at the intermediate Palomar Transient Factory (iPTF) was involved in the study of the closest SNIa explosion
in several decades, SN2014J.
We have now a new exciting result - an early glimpse of ultraviolet light from a Type Ia supernova, iPTF14atg, reveals what appears to be a shocked neighboring star. The results published in the journal Nature uncover the nature of the kind of objects that are used as standard … Continue Reading ››
The Swedish Research Council announced yesterday that a grant application to recruit the 2004 Nobel laureate Frank Wilczek to the Physics Department at Stockholm University was approved. This is extremely exciting news – also for the Oskar Klein Centre.
After six very successful years of OKC leadership, Lars Bergström was asked to become the new Dean of the Mathematics and Physics Section of the Science Faculty of Stockholm University. As a consequence, he has stepped down as OKC director and a new position at the Department of Physics at Stockholm University
has been announced to find a replacement. In the mean time, I will serve as director of the centre. It is with a sense of great pride – and a fair bit of apprehension - that … Continue Reading ››
One of the nearest supernova explosions in modern time was detected on Aug 24 by the PTF collaboration in the outskirts of the beautiful Pinwheel Galaxy M101 in the constellation Ursa Major, about 20 million light-years away.
The team had observed M101 on the previous night, and saw nothing on that spot, indicating that the first supernova detection took place within 24 hs of the actual explosion, an unusually early catch!
