Fiber networks
Fiber networks
Project description:
Project description:
Fibers are sub-parsec filamentary structures pervading the molecular clouds hosted in the interstellar medium. These fibers are deemed to be directly connected to the core formation and, therefore, to star formation. The goal of the project is to explore the physical properties of fibers and of their surrounding environment in connection to star formation in low- to high-mass regions.
Cosmic-ray ionisation
Cosmic-ray ionisation
Project description:
Project description:
Cosmic rays are a fundamental component of the interstellar medium. They influence both the dynamical state and chemistry of molecular clouds, possibly altering the timescales for star formation. The modelling and measurements of cosmic-ray ionisation are however challenging as of yet. The goal of the project is test new anaytical frameworks for the measurement of the cosmic-ray ionisation under different conditions in molecular clouds.

Project description:
High-spatial resolution observations in the millimitre and sub-millimitre regimes are achieved using interferometers. Despite their superb resolution, interferometers always provide an uneven and incomplete sampling of the target source. The resulting image is thus affected by systematic and unpredictable flux losses. The goal of the project is to promote the use of data combination techniques between interferometers and single-dish telescopes to retrieve reliable images of the target sources.

Project description:
Interstellar filaments are usually treated as isothermal infinite cylinders in equilibrium. Rarely even one of these conditions is satified. Filaments are instead part of complex networks that encompass several different environments and that are hierarchical in nature. The goal of the project is to use high resolution observations in order to derive physically sound constraints for theoretical models of realistic filaments.
