Abstract

A significant area (about 0.5 sq deg) of the cluster A3574 was surveyed using the large-format Thomson CCD, operating at f/1 on the AAT. The candidate cluster low-surface brightness galaxies (LSBG) were selected in terms of their position in isophotal magnitude-isophotal area plot, and 300 candidates with exponential sale-sizes greater than 2 arcsec. The largest objects have scale-sizes of 12-14 arcsec, which correspond to about 3 h/kpc if they are genuine cluster members. The lowest surface brightness objects found have central values around 26.5 Vmu. It is concluded that A 3574 has a particularly large LSBG content both in terms of the surface density and the LSBG-to-giant-galaxy ratio. A catolog of the 300 candidate objects is presented and compared with the LSBG population of this cluster.
