"Breaks in gamma-ray spectra of distant blazars and transparency of the Universe"
18th April 2013
Brightest ever observed gamma-ray flare from blazar Markarian 421. The very high energy gamma-rays were observed by the MAGIC telescopes located in Canary Island of La Palma. The results were obtained by researchers from Tuorla Observatory and Finnish Centre for Astronomy with ESO (Elina Lindfors, Kari Nilsson, Riho Reinthal, Aimo Sillänpää and Leo Takalo). The extraordinary flaring event is currently followed by all blazar researchers. Riho Reinthal, PhD student in Tuorla Observatory, has been following the source closely with the optical KVA telescope at La Palma, and the observations show that the source has also reached historical high state in optical.
The historical high state has also get attention in the media and was reported in the BBC news (http://www.bbc.co.uk/news/science-environment-22162806).
14th December 2012
Using computer simulations, scientists from Hawaii and Seppo Mikkola from
Tuorla observatory have figured out how wide binary stars, two stars that orbit each other at a
distance up to a light-year, form. The results were published in the Nature Letter (nature11662).
