Structural analysis of the Sextans dwarf spheroidal galaxy

Roderick, Tammy; Jerjen, Helmut; Da Costa, Gary; Mackey, Dougal


We present wide-field g- and i-band stellar photometry of the Sextans dwarf spheroidal galaxy and its surrounding area out to four times its half-light radius (rh = 695 pc), based on images obtained with the Dark Energy Camera at the 4-m Blanco telescope at CTIO. We find clear evidence of stellar substructure associated with the galaxy, extending to a distance of 82 arcmin (2 kpc) from its centre. We perform a statistical analysis of the overdensities and find three distinct features, as well...[Show more]
