Interstellar Medium Astrophysics (ISMA) Group

PI: Assoc. Prof. Dr Alvaro Hacar

Our mission

The Interstellar Medium (ISM) is the tenuous material (gas + dust) that exist in the space between stars within a galaxy. Using state-of-the-art, radio astronomical observations the Interstellar Medium Astrophysics group investigates the physical and chemical properties of the ISM as crucial ingredients to understand the origin of new stars and planets, the lifecycle of galaxies, and the physico-chemical evolution of the Cosmos. 

Research focus

  • Initial conditions for star formation: characterization of the ISM structure (clouds, filaments and cores) leading to the formation of low- and high-mass stars across the Milky way
  • Structure and Evolution: physical and chemical descriptions of the ISM
  • Astrochemistry: molecular content and emission properties of the cold ISM
  • Radioastronomy: (sub-)mm line and continuum observations using single-dish and interferometric radio facilities (e.g. ALMA)


Our groups hosts the "Emergence of high-mass stars in complex fiber systems" (EMERGE) project, a ERC-StG initiative on the study of the origin of high-mass stars using ALMA observations.
