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 [...]

First report with evidence that pandas lived in our country millions of years ago

Prehistoric Panda In the article „A late Turolian giant panda from Bulgaria and the early evolution and dispersal of the panda lineage“ published in the Journal of Vertebrate Paleontology, Prof. Nikolai Spassov from the National Museum of Natural History of BAS and his Chinese colleague Qigao Jiangzuo describe a new species of fossil giant panda (Agriarctos nikolovi) that inhabited Bulgaria about 6 million years ago, at the end of the Miocene. The description of the species is based on the finding of fossil teeth stored in the collection of NMNHS - BAS. The evolution of the panda is poorly known due to very limited fossil remains. It is assumed that the direct ancestor of today's panda is the fossil Chinese genus Ailuraerctos which lived 8-6 [...]

Innovations in Bulgarian speech synthesis and recognition

Innovations in the field of Bulgarian speech synthesis and recognition - a speaking programme, a medical dictaphone and an administrative "smart stenographer" were demonstrated by the Institute of Information and Communication Technologies (IICT-BAS) at BAS. The three innovative developments are based on original machine speech processing technologies and are based on recent advances in deep machine self-learning. Prof. DSc. Stoyan Mihov gave a demonstration for the first time of how the products work. The speaking programme makes it possible to generate speech as natural as possible for people with visual problems. During the presentation, the President of the Bulgarian Union of the Blind, Vasil Dolapchiev, presented the honorary sign of the Union to Prof. Stoyan Mihov. More than 10 000 people will be able to use [...]

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 [...]
