An Employee of the Centre for Astrophysics and Cosmology at the University of Nova Gorica Takes Part in the International Fermi LAT Project
As part of a study conducted with the help of the Fermi satellite, in which Dr. Gabrijela Zaharijas (Centre for Astrophysics and Cosmology at the University of Nova Gorica) also participated, researchers, using gamma radiation, were able to measure the total amount of light emitted by stars over the past 12 billion years.
Measurements have shown that the peak of star formation in the space fell within the period of about 10 billion years ago. New discoveries of the researchers are published in the.
The study of extragalactic background radiation is one of the tasks of the Fermi satellite, which this year has celebrated its tenth anniversary. The Fermi satellite measures the high-energy gamma radiation produced by high-energy processes in the space, such as the fall of a substance into a black hole, which is determined by special detectors. As part of the Fermi LAT project, the researchers investigated gamma radiation emanating from 739 blazars (extragalactic objects with a supermassive black hole in the core), which has been recorded with the help of the Fermi satellite for nine years.
The next working meeting of the participants of the Fermi LAT project – representatives of research institutions from the USA, France, Germany, Japan, Italy and other countries – will be organised by the University of Nova Gorica in Bled from 8 to 12 March 2019. During this event, the general public will receive detailed information about this and other important results of the astrophysical research conducted as part of the project.
It should be added that the research by Dr. Gabrijela Zaharijas was co-funded by the State Agency for Scientific Research through the research programme P1-0031, the infrastructure programme I0-0033 and the research project J1-8136.
