Complex organic molecules in the young hot core RCW 120 S2
M. S. Kirsanova, A. A. Farafontova
We analyse physical and chemical structure of the hot molecular core RCW120 S2, based on high-sensitivity (2-4 mK) APEX observations at 1.3 mm. The analysis reveals a rich molecula…
Single-dish observations and non-LTE analysis of CH3OH, HCN, and CO line emission in the Oort cloud comet C/2017 K2 (PANSTARRS)
M. S. Kirsanova, Ya. N. Pavlyuchenkov, A. O. H. Olofsson +1
We present pre-perihelion observations of methanol, carbon monoxide, and hydrogen cyanide in the Oort cloud comet C/2017 K2 (PANSTARRS), performed with the APEX 12-m and Onsala 20-…
Sky background accounting in spectral infrared observations of extended objects at the Caucasus Mountain Observatory of the SAI MSU
A. S. Gusev, A. M. Tatarnikov, S. G. Zheltoukhov +1
The Caucasus Mountain Observatory of the Sternberg Astronomical Institute of Moscow State University is the only one in Russia and one of the few in the world where is possible to…
Identifying Evolutionary Stages of Molecular Clumps through Unsupervised and Supervised Machine Learning
K. V. Plakitina, M. S. Kirsanova, A. B. Ostrovskii +3
The evolutionary classification of molecular clumps, crucial for understanding star formation, is commonly based on human-assigned categories derived from infrared (IR) emission an…
Tracking the dynamical, chemical and spectral evolution of molecular cores with PrestaLine: Gorynych
Olga Kochina, Dmitri Wiebe, Yaroslav Pavlyuchenkov +1
We present PrestaLine: Gorynych, a comprehensive numerical tool designed to model the dynamical, chemical, and spectral evolution of collapsing molecular cores from the prestellar…
Interstellar Medium in Extremely High Star-Formation Regions: A Prospect of Observations on the Millimetron Space Observatory
E. O. Vasiliev, S. A. Drozdov, P. V. Baklanov +5
High star-formation rate and active galactic nucleus' emission can significantly transform the interstellar medium. In ultra-luminous infrared galaxies, in which the star-formation…
