Python programming language
- 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 redshift z
- Script V: correction of emission lines of galaxy sample for MW dust extinction and intrinsic dust extinction. Then, best-fit linear relation between log ([OII]) vs log (H-alpha). Finally, star-formation rate estimate from [OII], H-beta and H-alpha
- Script VI: SFR vs. stellar mass in a sample of galaxies
- Script VII: calculating the chemical enrichment (metallicity) of a sample of galaxies and finding the linear correlation between the metallicity and the stellar mass
