Research Interests

Ralf Klessen’s primary research goal is to identify and characterize the physical processes that govern the structure and dynamical evolution of the interstellar medium and the birth of stars at present days as well as in the early universe. Scientific interests include gas dynamics and chemistry in the interstellar medium, statistical description of astrophysical turbulent flows, dynamo processes, gravitational collapse and formation of stars and stellar clusters, stellar dynamics, and the development and optimization of numerical algorithms in computational astrophysics.

Research Funding in Past 10 Years

Ralf Klessen is one of three speakers of the excellence cluster STRUCTURES: A unifying approach to emergent phenomena in the physical world, mathematics and complex data at Heidelberg University (35+ million over 7 years). He is deputy speaker of a Germany-wide priority program SPP 1573 Physics of the Interstellar Medium (2 million €/year for six years for about 40 ISM related projects in Germany). Ralf Klessen is also deputy speaker of the Heidelberg collaborative research project SFB 881 The Milky Way System (providing ~2 million €/year in 2011 – 2022 for astronomical research in Heidelberg). Ralf Klessen also is PI of the ERC Advanced Grant STARLIGHT: Formation of the First Stars ending in January 2019, and he is one of four PIs of the ERC Synergy Grant ECOGAL: Understanding our Galactic ecosystem – From the disk of the Milky Way to the formation sites of stars and planets that runs from 2020 to 2025. In total, he has been awarded over 7 million € in personal grants in the past 10 years. Other researchers in the star formation group in Heidelberg have solicited a total of 2.2 million € in additional grant money.
