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 [...]

IA’s Scientific achievement of 2021 is the study of a comet – the Solar system’s oldest interstellar visitor

Source: ЕSO, O. Hainaut The Institute of Astronomy with National Astronomical Observatory-BAS (IA with NAO) has named the results of the observations of comet 2I/Borisov, also known as C/2019 Q4 (Borisov), scientific achievement of 2021. They were conducted by an international team of scientists with the participation of IA researcher Assoc. Prof. Dr. Galin Borisov . Comet 2I/Borisov was discovered on 30 August 2019 by astronomer Gennady Borisov at the MARGO Observatory, Crimea, and is believed to be the most authentically preserved cosmic object - a sojourner in our solar system, second only to the asteroid 1I/'Oumuamua. The team of astronomers led by Dr. Stefano Bagnulo from the Armagh Observatory, Assoc. Borisov and their colleagues from France, Italy, Spain, the UK and the [...]
