Df. Demello et al., A CATALOG OF FAINT INTERACTING GALAXIES IN PAIRS AND GROUPS, The Astrophysical journal. Supplement series, 108(1), 1997, pp. 99-153
We have carried out an extensive survey of faint galaxies in order to
examine the rise in the merger rate with redshift and to study the sta
tistical relations between close interacting galaxies and the field ga
laxy population. In this paper, we present the catalog of faint pairs
and groups of galaxies of 46 equatorial fields taken with the Cerro To
lolo Inter-American Observatory 4 m prime focus. The data set contains
73,988 galaxies, covering a total area of 2.23 deg(2). We have found
1751 isolated pairs and 30 groups of galaxies within 19 < m(R) < 22 an
d 2'' < theta < 6'' in this area. Our results clearly show an increase
in pairs and groups of galaxies in comparison with a randomly generat
ed catalog.
