Title: Discovering new faint satellites and streams beyond the Local Group: the PISCeS survey

Abstract:
We present the first results from our wide-field resolved Panoramic Imaging Survey of Centaurus 
and Sculptor (PISCeS), aimed at investigating the halo of two nearby galaxies (D~3.5 Mpc) out 
to a galactocentric radius of 150 kpc with Magellan/Megacam. Our goal is to search for faint 
satellites in two environments substantially different from the Local Group, i.e. the loose 
Sculptor group of galaxies and the Centaurus A group dominated by an elliptical. Our survey to 
date has led to the discovery of ~20 satellites and additional streams/substructures which we 
could place at the distance of the host galaxies. The PISCeS survey provides the first complete 
census of dwarf satellites around NGC5253 and Centaurus A down to an unprecedented 
M_V<-8. Our results represent a crucial step in refining theoretical modeling of the different 
physical processes acting on star formation at the low-mass end of the galaxy luminosity 
function, to ultimately achieve a more complete picture of the galaxy formation process.
