Spectral Analysis of the Stromlo-APM Survey II. Galaxy luminosity function and clustering by spectral type
We study the luminosity function and clustering properties of subsamples of local galaxies selected from the Stromlo-APM survey by the rest-frame equivalent widths of their Hα and [O ii] emission lines. The bJ luminosity function of star-forming galaxies has a significantly steeper faint-end slope than that for quiescent galaxies: the majority of sub-L∗ galaxies are currently undergoing signifi...
متن کاملSpectral Analysis of the Stromlo-APM Survey I. Spectral Properties of Galaxies
We analyze spectral properties of 1671 galaxies from the Stromlo-APM survey, selected to have 15 ≤ bJ ≤ 17.15 and having a mean redshift z = 0.05. This is a representative local sample of field galaxies, so the global properties of the galaxy population provide a comparative point for analysis of more distant surveys. We measure Hα, [O II] λ3727, [S II] λλ6716, 6731, [N II] λ6583 and [O I] λ630...
متن کاملAutofib Redshift Survey: II – The Evolution of the Galaxy Luminosity Function by Spectral Type
We determine the evolution of the galaxy luminosity function (LF) as a function of spectral type using the Autofib redshift survey, a compendium of over 1700 galaxy redshifts in various magnitude-limited samples spanning bJ=11.5–24.0. To carry out this analysis we have developed a cross-correlation technique which classifies faint galaxy spectra into one of six types based on local galaxy templ...

We determine the evolution of the galaxy luminosity function (LF) as a function of spectral type using the Auto b redshift survey, a compendium of over 1700 galaxy redshifts in various magnitude-limited samples spanning bJ=11.5{24.0. To carry out this analysis we have developed a cross-correlation technique which classi es faint galaxy spectra into one of six types based on local galaxy templat...
متن کاملPower Spectrum Analysis of the Stromlo-APM Redshift Survey
We test estimators of the galaxy power spectrum P (k) against simulated galaxy catalogues constructed from N-body simulations and we derive formulae to correct for biases. These estimators are then applied to compute the power spectrum of galaxies in the Stromlo-APM redshift survey. We test whether the amplitude of P (k) depends on galaxy luminosity, but find no significant luminosity dependenc...
