Abstract:
A small fraction (<10%) of the SDSS main galaxy (MG) sample has not
been targeted with spectroscopy due to the effect of fiber
collisions. These galaxies have been compiled into the input catalog
of the LAMOST ExtraGAlactic Surveys and named the complementary
galaxy sample. In this paper, we introduce this project and status of
the spectroscopies associated with the complementary galaxies in the
first two years of the LAMOST spectral survey (till Sep. of 2014).
Moreover, we present a sample of 1102 galaxy pairs identified from the
LAMOST complementary galaxies and SDSS MGs, which are defined as two
members that have a projected distance smaller than 100h70-1kpc
and a recessional velocity difference smaller than 500km/s.
Compared with galaxy pairs that are only selected from SDSS, the
LAMOST- SDSS pairs have the advantages of not being biased toward
large separations and therefore act as a useful supplement in
statistical studies of galaxy interaction and galaxy merging.
Description:
We combine the redshifts of the LAMOST complementary galaxies sample
with the SDSS spectroscopic main galaxy (MG) sample to identify new
galaxy pairs.
