Abstract
The local space density of galaxies with 60 μm luminosity greater than VL_v (60 μm) ≳ 10^(10) L_☉ is derived from a sample of bright galaxies detected in the IRAS survey. The sample is complete to 5 Jy at 60 μm and covers one-quarter of the sky. With a maximum redshift in the sample of 0.081, this sample represents a survey of the infrared characteristics for infrared bright galaxies in the local universe. The space density is described by p(L) ≈ 1.7 X 10^(-3) (L/10^(10) L_☉)-2 Mpc^(-3) over the range 10^(10) L_☉ < VLv, (60 μm) ≾ 3 X 10^(12) L_☉. The space density of infrared bright galaxies appears comparable to or larger than other classes of extragalactic objects for total luminosities greater than 10^(11) L_☉ . The space densities of infrared bright galaxies and non-Seyfert Markarian galaxies are very similar for L < 2.5 x 10^(11) L_☉. The far-infrared energy density in the local universe is close to that in visible light. It is suggested that a substantial fraction of all galaxies with L > 10^(10) L_☉ undergo a period of extreme infrared activity.
