The Luminosity function for different morphological types in the CfA redshift survey

摘要: We derive the luminosity function for different morphological types in original CfA Redshift Survey (CfA1) and first two slices of Extension (CfA2). CfA1 is a complete sample containing 2397 galaxies distributed over 2.7 steradians with m(sub z) less than or equal 14.5. The CfA2 contain 1862 0.42 z)=15.5. shapes E-S0 spiral functions (LF) are indistinguishable. do not confirm steeply decreasing faint end found by Loveday et al. an independent southern hemisphere. demonstrate that incomplete classification deep redshift surveys can lead to underestimates elliptical could be partially responsible difference between survey other local field surveys. LF Magellanic spirals irregulars very steep. Sm-Im well fit Schechter M*=-18.79, alpha=-1.87, phi*=0.6x10(exp -3) M(sub -13. These largely excess at general function. abundance intrinsically faint, blue nearby affects interpretation number counts. dwarf population increases expected counts B=25 no-evolution, q(sub 0)=0.05 model factor standard no-evolution estimates. dwarfs change median 10 percent . Thus steep may contribute reconciliation
