Interstellar Medium - Spring 2018
Masters Course in Astronomy, Leiden University
LECTURER: Prof. Xander Tielens
ASSISTANTS: Kimberly Emig, Cornelia Pabst
The space between the stars is filled with matter, magnetic fields, and radiation. This course describes this ‘interstellar medium’ as an an integral part of galactic ‘ecosystems’. It provides an overview of the known constituents of the ISM (ionized, atomic, and molecular gas; dust; magnetic fields; cosmic rays; EM radiation), and the different environments in which these are encountered (the 2- and 3-phase models of the ISM) along with the observational diagnostics (atomic and molecular spectroscopy; spectral energy distributions). It discusses the physical processes that govern the interactions within the ISM and with stars (energy balance; shocks). And it highlights the relationships between the ISM and stars and their host galaxies (birth and death of stars; supernovae; nuclei of active galaxies).

SCHEDULE & CONTENT
Lectures will be held in room HL414 on Wednesdays from 13:30-14:15, 14:30-15:15.
Exercise classes (EC) will be held somewhat bi-weekly (see below) following lecture, in room HL414 from 15:30-16:15, 16:30-17:15. A homework assignment will be due each day an EC is held -- thus six assignments in total -- and at 13:30, at the start of the day's lecture.
We are also inlcuding an outline of the course content as a guide for following along with the book and lecture material.
The final exam takes place Thursday, May 24 from 10:00-13:00 in room HL414.
The exam grades can be found here, listed as student number and score.
The re-take exam will be held Wed, June 20 from 14:00-17:00 in HL207.
The grades of the re-take exam can be found here, listed as student number and score.
