Learning outcomes
At the end of the course, each student will be familiar with
various packages (graphics, type-writing, maths, optical
benchworks) with wide diffusion, beyond the astronomical community.
He will make use of skills acquired in earlier stages of her/his
learning (e.g. statistical analysis). She/he will be able to easily
generate diagrams and multimedia presentations allowing an
efficient illustration of the science cases, both on outreach and
on professional levels.
Course contents
The activities are organized into 3 sessions:
1. Celestial coordinates conversion, search for and critical
evaluation of info in the NED (NASA Extragalactic object Database).
Selection of a literature work and organization of a presentation,
useful in the perspective of the laurea session work.
2. Production of a color index - magnitude diagram for a star
globular cluster. Evaluation of the turn-off point and comparison
with an isochrone. Measure of the distance modulus. Production of a
short LaTeX report.
3. Study of optical spectra taken at the Telescopio Nazionale
Galeleo. Measurement of the redshift and evaluation of its
uncertainties from spectral lines. Determination of the mean
redshift and of the velocity dispersion of the cluster galaxies by
means of a basic use of the NOAO/IRAF package. Evaluation of the
virial mass of the cluster of galaxies and its uncertainties.
Production of a LaTeX report.
Readings/Bibliography
On line manuals of various packages;
Allen's Astrophysical Quantities (A.N. Cox editor) AIP press,
Springer
Teaching methods
Short introductory lectures and then individual lab activities.
Discussion of the main points during the work.
Assessment methods
The presentation of the first activity and and the two written reports for the remaining tests will constitute the
evaluation work carried out.
Teaching tools
Activities will take place in the Informatics Lab, where various
packages will be used (a browser, SuperMongo, LaTeX, OpenOffice,
IRAF, etc.)
