Welcome the new director!

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 turn the page to a new year

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 ››

Another interesting and very successful year of the Oskar Klein Centre

As the year 2013 is now nearing its end, it is time to recapitulate the main events of the year from the OKC perspective. If I temporarily put on my Nobel hat (being the scientific secretary of the Nobel Committee for Physics) the main event from the Stockholm horizon is without doubt the Nobel Prize to Francois Englert and Peter Higgs for their almost 50-year old prediction from the early 1960’s that was so spectacularly confirmed by the ATLAS and CMS experiments at CERN’s LHC accelerator last year.

End of a good Oskar Klein Centre year

This year has been very interesting for the OKC. The highlight was of course the Nobel Prize for Saul Perlmutter, Brian Schmidt and Adam Riess.The half-day December 12th immediately following the Prize ceremony, organized by Ariel Goobar and Jesper Sollerman, was a great success. I could not be present, unfortunately, but I can recommend the video from the very memorable colloquium session, at http://videos.albanova.se/colloquia/2011/ – it is well worth watching, as is the colloquium the day after on global warming by Rich Muller (who was one of the forefathers of the Supernova Cosmology Project).

What is the perfect size for a research group?

If you are thinking about your research group and are wondering on whether to include more people you better read this.

Ralph Kenna from the University of Coventry and Bertrand Berche from the University of Nancy (France) have analyzed the correlation between quality and research group size for different areas, based on data collected for the UK’s 2008 Research Assessment Exercise (RAE). Their findings are very interesting. While one could think that more people would get better results together, it seems that this is not true indefinitely.

The OKC Day

This spring’s Oskar Klein Centre day took place in beautiful surroundings yesterday (Monday, May 30th), at Villa Källhagen – a nice conference centre in Djurgården near the water. As is now customary in these general OKC meetings, first a summary of the activities of the working groups was done, with slide presentations by Jonas Enander (Dark Energy), Christoph Clement (Dark Energy), Elena Moretti and Josefin Larsson (Extreme Objects) and Rachel Rosen (Fundamental Theory). Although the working group for Structure formation was left without slides due to a late cancellation, Lucia Gaita and Kanan Datta made a very good, unprepared presentation of their activities.
