An HI Survey of LSB galaxies selected from the APM Survey
نویسندگان
چکیده
We present preliminary results of a neutral hydrogen (HI) redshift survey to find low surface brightness (LSB) galaxies in the very nearby universe. Our sample consists of all galaxies in the APM catalog (Maddox et al. 1990) with a mean surface brightness of μ ≥ 24 mag/arcsec, down to a magnitude limit of bj ≤ 17. With the Parkes 64m radiotelescope 35 objects were detected at v < 4300 km s. The resulting luminosity function, HI mass function, and for the first time field mass function are presented. It is found that LSBs make a negligible contribution to the overall integrated luminosity, HI mass, and total mass contained in galaxies.

UBR 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...

Using the refurbished 305m Arecibo Gregorian Telescope, we detected 43 low surface brightness (LSB) galaxies from the catalog of O'Neil, Bothun, & Cornell (1997a). The detected galaxies range from 22.0 mag arcsec −2 ≤ µ B (0) ≤ 25.0 mag arcsec −2 , with colors ranging from the blue through the first detection of a very red LSB galaxies (B−V = −0.7 to 1.7). The M HI /L B of these galaxies ranges...
متن کاملThe HI Companions of HII Galaxies and Low Surface Brightness Dwarf Galaxies
I study the VLA HI survey of HII galaxies by Taylor et al. (1995, ApJS, 99, 427; 1996, ApJS, 102, 189) and the VLA HI survey of low surface brightness (LSB) dwarf galaxies by Taylor et al. (1996, in press) to investigate the role of galaxy interactions in triggering the bursts of massive star formation seen in HII galaxies. Comparing the two surveys, I find that HII galaxies have companions mor...
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 کاملFinding the Bivariate Brightness Distribution of Galaxies from an HI Selected Sample
A method is presented that will enable the bivariate luminosity/surface brightness distribution of galaxies to be determined from a relatively small HI selected sample. This will be taken from the HI Parkes All Sky Survey (HIPASS). The advantages of using an HI sample in order to avoid the selection effects that are present at optical wavelengths are discussed. We are developing an algorithm to...
