The Center for Laboratory Astrophysics is being created to complete the tasks of megagrant “The origin and evolution of organic molecules in our Galaxy” (agreement between the Ministry of Science and Higher Education of the Russian Federation and Lebedev Physical Institute No. 075-15-2021-597).

The head of both the grant and the Center is the Professor of the University of Hawaii at Manoa (USA) Ralph Ingo Kaiser. Project coordinator from the Samara Branch of the Lebedev Physical Institute (SB LPI), Director of the SB LPI V. N. Azyazov.

The purpose of the project is to study the mechanisms of complex organic compounds formation on ice-covered nanoparticles in molecular clouds and in star-forming regions.

Research methods:

  • conducting astrophysical experiments that reproduce the conditions of the interstellar medium;
  • calculations of the molecules electronic structure;
  • astrochemical modeling;
  • astronomical observations.
The components of the Interdisciplinary Center for Laboratory Astrophysics, their scientific tasks RO1-RO5 and the connections between them
Key tasks:
  • design, construction and launch of a new generation facility for the study of cryogenic surface processes (CSP).
  • Building a unified concept of the molecular mass growth fundamental processes, which lead to the main classes of organic compounds in extraterrestrial ice, based on the experimental data obtained in the project.
  • Testing the mechanisms of synthesis of organics such as functionalized aromatics of RNA and DNA relevant to the origins of life theme in molecular clouds and star-forming regions by comparison with the results of astrochemical modeling and astronomical observations.
Expected results:
  • Fundamental regularities of radiation-induced physicochemical processes in low-temperature interstellar ice.
  • Mechanisms of organic compounds growth in interstellar ice.
  • A refined concept of the organic compounds evolution in space.
Collaboration:
  • Samara National Research University,
  • University of Hawaii at Manoa, USA,
  • International University of Florida (Florida International University, USA).
