Abstract:
We announce the initial release of data from the Ohio State University
(OSU) Bright Spiral Galaxy Survey (OSUBSGS), a BVRJHK imaging survey
of a well-defined sample of 205 bright, nearby spiral galaxies. We
present H-band morphological classification on the Hubble sequence for
the OSU Survey sample. We compare the H-band classification to B-band
classification from our own images and from standard galaxy catalogs.
Our B-band classifications match well with those of the standard
catalogs. On average, galaxies with optical classifications from Sa
through Scd appear about one T type earlier in the H band than in the
B band, but with large scatter. This result does not support recent
claims made in the literature that the optical and near-IR
morphologies of spiral galaxies are uncorrelated. We present detailed
descriptions of the H-band morphologies of our entire sample, as well
as B- and H-band images for a set of 17 galaxies chosen as type
examples and BRH color-composite images of six galaxies chosen to
demonstrate the range in morphological variation as a function of
wavelength.
