The AAO/UKST SuperCOSMOS Hα survey

The UK Schmidt Telescope (UKST) of the Anglo-Australian Observatory completed a narrowband Ha plus [N II] 6548, 6584-A survey of the Southern Galactic Plane and Magellanic Clouds in late 2003. The…

Shell Structure in the Fornax Dwarf Spheroidal Galaxy

We present initial results from a wide-field photometric survey of the Fornax dwarf spheroidal (dSph) galaxy. The focus here is on a small overdensity of stars located approximately 17′ (670 pc in…

0422–476: a shell galaxy with azimuthally distributed shells

A morphological and two-colour CCD photometry study of the shellgalaxy 0422-476,one of the richest known azimuthally distributed shell galaxies, is presented. Takingthis galaxy as a prototype, a…

A feather on the hat: tracing the giant stellar stream around the Sombrero galaxy

Recent evidence of extremely metal-rich stars found in the Sombrero galaxy (M104) halo suggests that this galaxy has undergone a recent major merger with a relatively massive galaxy. In this paper,…

The Southern Spring

The Helix Nebula (NGC 7293) is the nearest planetary nebula to the Sun, at a distance of about 650 light-years. The remnant of a dying, Sun-sized star, the nebula is composed of a series of…

Polarization in the Magellanic Clouds

Abstract We present preliminary results from a number of deep radio polarization surveys being made of the Magellanic Clouds at 2.3 GHz, 4.75 GHz and 8.55 GHz. Extended and linearly polarized radio…

The Southern Fall

The Carina Nebula (NGC 3372) is one of the largest and brightest nebulae in the sky, and we see it from a distance of 7500 light-years. It extends for some 260 light-years across the southern Milky…

Echoes of the Supernova

The light echoes of SN 1987A are studied using photographs of the Tarantula nebula, including Sanduleak -69 deg 202, taken from 1984 to 1988. The formation of light echoes, and the process of…

Two Colour CCD Photometry of Malin-Carter Shell Galaxies

Shells may be the result of the disruption of a small companion in the potential of a much larger galaxy (e.g., Hernquist & Quinn, 1986; Dupraz & Combes, 1985), the disturbance of a disk system in a…
