50 years Bulgaria – space state

A celebration on the occasion of the 50th anniversary of Bulgaria's proclamation as a space state was held in “Prof. Marin Drinov" Hall of the Academy. The Space Research and Technology Institute (SRTI) of the Bulgarian Academy of Sciences was the organizer of the event which took place under the patronage of President Rumen Radev. For us, space is an expression of the ambitions of a nation where it positions itself in terms of human progress and the future of humanity, President Rumen Radev said in his greetings at the solemn celebration. It is a tribute to the pioneers, 50 years ago, that they positioned Bulgaria at the forefront of human progress, the Head of State said. We can only also be proud of [...]

Scientists from the Institute of Astronomy with NAO take part in a publication in “Nature”

An artistic interpretation of the blazar phenomenon and the jet of high-energy particles it emits The study of BL Lac blazar is by an international team with Bulgarian participation An international team involving Bulgarian astronomers has detected cycles of oscillating brightness in a jet of high-energy particles emitted by the blazar BL Lac. The results of this research were published in one of the most prestigious scientific journals in the world - "Nature", no. 7926, Volume 609, 8 September 2022. Observations from 37 different telescopes in 13 countries were used to realize this study. Our results were obtained with the 2-m RCC telescope and the 50/70 cm Schmidt telescope at the National Astronomical Observatory Rozhen, as well as with the 60-cm telescope at the [...]

Evolutionary processes in astrophysics: synergy of observations with theory

The North America Nebula - a cradle of star formation The project "Evolutionary processes in astrophysics: synergy of observations with theory" of a team of scientists from the Institute of Astronomy with National Astronomical Observatory (IA with NAO) has been successfully completed. The scientific achievements of the project are in the areas of galaxy evolution, star formation, main sequence stars, symbiotic stars, the Sun and the Solar System. The results have been published in 70 papers, with a total impact factor = 213.326 and a total impact rank = 10.418, and presented at 35 national and international conferences. A total of 45 participations in scientific forums were made during the two phases of the project. Three dissertations were defended and 2 scientific forums [...]

Scientists from the Institute of Astronomy with NAO with publication in „The Astrophysical Journal“

Study reveals in detail the quiet Sun at low frequencies Calibrated interferometric images of the quiet solar corona on 07.08.2021 in low frequencies (24.60-78.90 MHz) observed by LOFAR. The Sun is an active star that has significant radio emission over a wide frequency range from kHz to THz, and the solar atmosphere has a complex distribution of magnetic field, plasma density and temperature. These different properties of the solar atmosphere lead to different radio emission characteristics at different frequencies. Interferometric imaging observations of solar low-frequency emission can help diagnose the properties of the plasma at high altitudes in the solar atmosphere. Calibrated interferometric images of the quiet solar corona on 14.08.2021 at low frequencies (24.60-78.90 MHz) as observed by LOFAR. In [...]

Bulgarian achievements in space science

Demonstrations with drones and on a stationary training simulator were made by scientists from the Space Research and Technology Institute (SRTI) in the Open Day on the occasion of the International Day of Aviation and Cosmonautics – 12 April. The researchers gave lectures on new space research projects and talked about Bulgarian achievements at the Institute. Original Bulgarian equipment is working on the International Space Station. An example is the space radiation instrument, the LIULIN-SET dosimeter, and in the near future a dosimeter of the LIULIN series is expected to transmit specific information from the very surface of Mars. There is an anniversary exhibition which shows visitors the spacesuit of the pilot-cosmonaut Alexander Alexandrov, the first Bulgarian instrument "P-1", as well as many other [...]

Bulgarian technology measures radiation on the International Space Station

The Liulin-SET instrument, developed at the Space Research and Technology Institute of the Bulgarian Academy of Sciences (SRTI – BAS) will fly into space on 19 February. The head of the team that developed the instrument is Prof. Tsvetan Dachev. Members are the scientists Assoc. Prof. Mityo Mitev, Sen. Asst. Prof. Borislav Tomov, Sen. Asst. Prof. Yuri Matviychuk and Eng. Plamen Dimitrov from the Solar Terrestrial Physics Department. This is the 23rd instrument, developed in the department that will work in space. […]
