STELLAR Schools on Radio Astronomy Research and Technologies

Undergraduates, Master and PhD students and young scientists in astronomy, physics, engineering, computer science and mathematics can apply for participation in the final three schools of the STELLAR project ("Scientific and Technological Excellence by Leveraging LOFAR Advances in Radio Astronomy"). STELLAR (2020-2023) is a transformational project under Horizon 2020, training the next generation of Bulgarian radio astronomers related to the upcoming construction and future sustainable development of a Bulgarian station of the pan-European distributed low-frequency radio telescope LOFAR. Participants in the project and organisers of the schools are the Institute of Astronomy with NAO - BAS and the Technical University of Sofia, in partnership with the Dublin Institute for Advanced Studies DIAS and the Netherlands Institute for Radio Astronomy ASTRON. STELLAR aims to develop [...]

The tower for the new telescope at NAO Rozhen is ready

The construction of the tower for the new 1.5-meter telescope at the National Astronomical Observatory in Rozhen at the Institute of Astronomy of BAS has been completed. The 6-meter dome has been installed and the finishing works on the internal insulation of the tower are currently being carried out, as well as the installation of the power supply and the fiber-optic internet cable. Due to the onset of winter in the Rhodope Mountains and the snow cover that has formed in the area, the installation of the telescope itself will be postponed until spring 2023. During the last months, activities on the preparation of the telescope site have been carried out at NAO Rozhen. At the end of 2021, the geological survey and geodetic measurement [...]

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 [...]
