Information

Ziele, Inhalte und Methode der Lehrveranstaltung

That dwarf galaxies are postulated as cosmological building blocks of the massive galaxies and that they outrange by number all morphological galaxy types, make them extremely interesting astrophysical objects. They span a wide mass range of several orders of magnitude, but do not simply appear as small editions of the massive Hubble galaxies. Due to their low masses they are sensitive to energetic perturbations, internally as e.g. by stellar winds and supernova explosions, and also externally by environmental effects e.g. as satellites of massiv galaxies or members of galaxy clusters. Because these different effects lead to their large structural variety, they serve as ideal testbeds for astrophysical processes. Moreover, their role within the cosmological structure formation postulating a dominance of Dark Matter will be considered from observations and numerical simulations.
This lecture will at first introduce into the morphological classification of dwarf galaxies, correlate their structural properties with their existence as satellites, as clusters members, and in the field, and explore the physical processes causing such variety. Moreover, we will shed light on the formation paths of dwarf galaxies in tidal arms of encounters/mergers of massive galaxies and the possible origin of the newly detected classes of ultra-compact and ultra-diffuse DGs.

Art der Leistungskontrolle und erlaubte Hilfsmittel

Selected topics of formation, evolution, and structure of Dwarf Galaxies will be elaborated from the literature and individually presented by talks. A vital participation during the course is expected.
Very welcome are students with particular interest in extragalactic astrophysics.

Mindestanforderungen und Beurteilungsmaßstab

The students should be currently involved into master study in Astronomy, i.e. having finished their Bachelor study, or have successfully completed their master degree. Interest and knowledges in extragalactic Astrophysics are advantageous for a successful understanding, discussion, and presentation of the topic. Recaps of previous sessions will be asked and discussed.
The successful evaluation requires 80% participation in the courses and one presentation of selective recent publications for 30-45 min by each participant.
Individual grades will depend on active participation and scientific contributions during the courses, the gained knowledge, and the quality of the presentation.

Prüfungsstoff

Literatur

Textbooks and mostly actual literature will be recommended during the course.
