Abstract:
We present a new catalog of isolated galaxies obtained through an
automated systematic search. These 2980 isolated galaxies were found
in ∼2099°2 of sky in the Sloan Digital Sky Survey Data Release 1
(SDSS DR1, http://www.sdss.org/dr1/) photometry. The selection
algorithm, implementing a variation on the criteria developed by
Karachentseva in 1973, proved to be very efficient and fast. This
catalog will be useful for studies of the general galaxy
characteristics. Here we report on our results.
