Topic: stellar growth

Young stars eject powerful flows while they are still forming. This seminar reviews their observed properties and competing explanations for their origin. High-resolution observations from Hubble, Webb, ALMA and NOEMA reveal new structure and help evaluate how these outflows influence both stellar growth and planet-forming environments.

This seminar examines how galaxies assemble through both the accretion of gas along cosmic filaments and mergers with other galaxies. It connects tidal interactions and coalescence to the history of star formation. The discussion compares sustained stellar growth with bursts associated with dynamical encounters.
