Abstract:
Low surface brightness galaxies (LSBGs) are defined as galaxies that
are fainter than dark night sky and are important for studying our
universe. Particularly, edge-on galaxies are useful for the study of
rotational velocity and dynamical properties of galaxies. Hence here
we focus on searching for edge-on LSBGs. In order to find these
edge-on dim galaxies, a series of effects caused by inclination,
including the surface brightness profile, internal extinction, and
scale length, have been corrected. In this work, we present a catalog
of 281 edge-on LSBG candidates, which are selected from the crossmatch
between Sloan Digital Sky Survey Data Release 7 and the 40% ALFALFA
catalog. We also present the properties of these edge-on LSBG
candidates including the absolute magnitude, central surface
brightness, B-V color, scale length, and relative thickness. Our
result suggests that the correction of inclination effects is very
important for obtaining a complete sample of LSBGs.
Description:
Our low surface brightness galaxies (LSBGs) sample is selected from
the optical-HI crossmatch from the α.40 catalog (Haynes+ 2011,
J/AJ/142/170). This crossmatching catalog is produced by the ALFALFA
survey, which is a HI survey with a sky coverage of 7000deg2.
There are 15855 sources in the α.40 catalog, 15041 of which are
extragalactic objects. Since the Sloan Digital Sky Survey (SDSS) data
has a wide coverage and overlap with ALFALFA, 12468 of these
extragalactic sources have been found to have optical counterparts
from the SDSS Data Release 7 (DR7).
First, we did a preliminary selection of 1575 edge-on galaxies and
then, we have corrected the inclination effects to present a catalog
of a sample of 281 edge-on LSBG candidates.
