Course contents
a) Emission mechanisms and some aspects of synchrotron
theory (e.g. polarization, ageing, magnetic field etc.)
b) Radio emission of normal galaxies: HII regions,
supernovae, different components, the Milky Way (outline of the
optical and radio emission of the different components (disk,
halo), the spectral characteristics, the thermal and non-thermal
components; outline of the X and gamma emission; the magnetic
field).
c) Magnetic field: synchrotron emission, polarization,
Faraday rotation, Zeeman effect, magnetic field in the Galaxy and
in the galactic centre.
d) Interstellar medium: brief description of the composition,
HI, masers, molecules. Molecules and star formation in galaxies.
Molecules and kinematics in galaxies.
e) A multi-wavelength view of the Galactic Center: HI, radio
(spectrum, variability, polarization of the various components),
IR, molecules and maser, X emission.
f) Supernovae: optical characteristics, supernovae remnants (
radio properties, dynamical evolution, brightness-diameter
relation, energy considerations).
g) Pulsars: properties (distribution, period, prifile,
radio spectrum, brightness temperature, age, distance, luminosity
function). Neutron stars: mass, radius, moment of inertia,
structure, magnetosphere, energetics, gravitational physics in the
strong-field regime, keplerian and post-keplerian parameters, the
double pulsars.
h) Radio emission from stellar end-products: jets in cataclismic
variables, X binaries, microquasars (general properties,
superluminal motions, multi-frequency data in the context of the
current model).
i) Radio emission in spiral galaxies: spectrum,
polarization of the components, comparison with the X-ray emission,
luminosity function, radio-IR/radio-CO correlation and discussion
of a simple model, estimates of stellar formation, HI, rotation
curves, dark matter, Tully-Fisher relation, the environment.
l) Radio faint population: observational technique, counts,
radio/FIR relation, composition, optical and radio properties.
m) New radiotelescopes.
