We analyze a sample of galaxies with stellar masses greater than 1010M⊙ and with redshifts in
the range 0.025 < z < 0.05 for which HI mass measurements are available from the GALEX Arecibo SDSS Surve...

We derive a semi-empirical galactic initial mass function (IMF) from observational constraints. We assume that the star formation rate in a galaxy can be expressed as the product of the IMF, $\psi (m)...
