A Comparative Study of Star Formation Rate in Galaxies of Different Morphological Types

We study the star formation rate (SFR) of 3,079 galaxies at z < 1.468 drawn from the Sloan Digital Sky Survey (SDSS) DR6 sample. We visually classify the sample into different morphological types and measure the SFR along the Hubble sequence by using the SFR calibrations of Kennicutt (1998). We compare results from the each SFR calibration and discuss the difference of SFR in each type of galaxies.
