Dust: reddening and extinction, grain size distribution, dust extinction law and attenuation law, Galactic extinction correction.
4. Star-forming regions in galaxies, galaxy spectra, measuring redshift with spectra, interference of atmospheric absorption, sky emission and cosmic rays on galaxy spectra, dust extinction correction in galaxies, estimating the star formation rate in galaxies, photometric redshift, estimating the stellar mass of galaxies.
8. Cosmic chemical evolution, primordial nucleosynthesis, solar chemical abundances, nucleosynthesis in massive stars, cosmic cycling of matter, measuring chemical enrichment in galaxies with emission lines, mass-metallicity relation, different methods used to estimate metallicity
- Script I: fitting an emission line with a gaussian profile, showing the line and calculating the flux
- Script II: chi^2 minimisation with 2nd degree polynomium
- Script III: calculating dust extinction for emission lines in galaxies at redshift z > 0
- Script IV: luminosity distance calculated for a sample with redshit z
- Script V: correction for dust extinction in the Milky Way and intrinsic, then calculation of the star formation rate
- Script VI: calculating the chemical enrichment (metallicity) of a sample of galaxies and finding the linear correlation between the metallicity and the stellar mass
