Interview with Kanan K. Datta

Kanan Datta is one of the OKC fellows working at the Astronomy department since October 2009. He is doing his first postdoc studing the universe reionization, something that probably happened only about 200 million years after the Big Bang. He is originally from India, but he enjoys very much being in Sweden.

How do you like working at the Oskar Klein Centre?
I am quite satisfied. In the beginning it took some time to decide on the projects I want to work on, develop codes etc. So if I judge myself by the number of results I produced here, it is not so impressive. Nevertheless, together with my collaborators here I got some interesting new results and more results are coming up now. Apart from that, I think I learned a lot, developed some new tools which made me more confident than I used to be before I started my postdoc.

Socially, I really enjoy staying in Stockholm. It is a very beautiful city, very nice helpful people all around. This is the first time I am outside my country which made me worry before I came here. Everything was extremely new when I arrived in Stockholm. But I did not find any difficulty to settle here despite huge differences in culture, weather between Sweden and my home country India. I enjoy both very long nights during winter and also the long days in summer because they are new to me. It is also fun to walk on a frozen lake……

Why did you choose the OKC for doing your postdoc?
I always wanted to go outside my country for postdoc to work with experts in my field and learn something new and also for better scientific environment, facilities etc. So I agreed immediately when I got the postdoc offer from OKC. I am happy that I made this choice. I applied here because I wanted to continue my research on the reionization and probing it using 21-cm observations. Continue reading Interview with Kanan K.

First image from the Onsala LOFAR station

The Europe-wide, international LOFAR Telescope (Low Frequency Array) is the world’s largest radio telescope and observes radio waves with low frequencies.
LOFAR will map these radio signals and thereby see billions of light years out into space, into the era when the first stars formed, only a few hundred million years after the Big Bang. However, it will also investigate the environments of black holes, find extreme galaxies and pulsars, for planets around other stars and even investigate the nearest star, our Sun.

Spring time for LOFAR Sweden

As the Sun is finally warming up both the nature and people this far north, also the efforts to construct the Swedish LOFAR station awake from their winter sleep. From November until now snow and frozen soil stopped the work in its tracks, but today at Onsala near Göteborg on the west coast of Sweden, the building activities will recommence.

LOFAR is a European wide radio telescope consisting of stations spread out over the Netherlands, Germany, the UK, France and Sweden, with possibly more countries joining in the future. The stations can work independently as small radio telescopes, or they can send their data to a central processing unit in the Netherlands to mimic a giant radio telescope of a cross section of several thousands of kilometers. It will be exploring the sky at radio frequencies between 30 and 200 MHz, an ip to now mostly unexplored regime of the electromagnetic spectrum.
