Spectral 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 کاملSpectral 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 properties of galaxies in the Stromlo-APM redshift survey: clues on the local star-forming galaxies
We analyse emission-line properties of the bj-selected Stromlo-APM spectra (〈z〉 = 0.05). Because this is a representative sample, we can study the global spectral properties of the local galaxy population. We classify spectra according to their Hα emission, which is closely related to massive star formation. This study gives a comparative local point for analysis of more distant surveys. We sho...
متن کاملScale-invariant properties of the APM-Stromlo survey
We investigate the statistical properties of the APMStromlo redshift survey by using the concepts and methods of modern Statistical Physics. We find that galaxy distribution in this survey exhibits scale invariant properties with fractal dimensionD = 2.1± 0.1, up to∼ 40h−1Mpc, i.e. the limit of its statistical validity, without any tendency towards homogenization. No intrinsic characteristic sc...
متن کاملUBR CCD photometry of Stromlo-APM galaxies
We present CCD photometry in the Johnson-Kron-Cousins UBR bands for a sample of 320 galaxies selected from the Stromlo-APM Redshift Survey. We use this CCD data to estimate the galaxy luminosity function in the U , B, R and bJ bands, finding consistent results with earlier work. Fainter galaxies serendipitously observed on our CCD frames allow a check of the photometric calibration of the APM G...
