Fig. 3


The phase density of stars in the local Universe as a function of the absolute magnitude of the galaxies that produce them, as derived from the Millennium Galaxy Catalogue. The panels show both the individual disk and spheroid components and the sum of the two. The projection of these plots by integrating over the distribution of galaxy luminosities shows the total stellar phase density of the local Universe. Here, f is expressed in Mpc-3(kms-1)-3 and m in pc3(kms-1)3Mpc-3. The dashed and dotted line show, respectively, the mean trend in effective and central phase density for components considered by Mao & Mo (1998).
