... Neutral hydrogen observations of the spiral galaxies NGC 6221 and NGC 6215 with the Australia Telescope Compact Array (ATCA) reveal a wide, two-stranded bridge of at least 3 x 10^8 Msun which can be traced between the two galaxies over a projected distance of 100 kpc. ...

... We present a photometric and spectroscopic study of the unique isolated nearby galaxy KKR25. The isolated dwarf spheroidal (dSph) galaxy KKR25 was discovered by Karachentseva, Karachentsev Richter (1999, A , 135, 221) during the search of dwarf galaxies in the direction of the Local Void. In spite of its isolation KKR 25 has no gas and looks like a normal dwarf spheroidal system. ... This is the first known planetary nebula in a dwarf spheroidal galaxy outside the Local Group. ...

We investigate which conditions of dust attenuation and stellar populations allow models of dusty, continuously star-forming, bulge-less disc galaxies at 0.8 5.3, IC-K > 4, J-K > 2.3). ... We find that synthetic discs can exhibit red optical/near-infrared colours because of reddening by dust, but only if they have been forming stars for at least ~1 Gyr. ... This explains the large fraction of observed, edge-on disc-like galaxies with Ks ~ 4. ... In conclusion, red disc-like galaxies at 0.8 . ...

... Astrophysics Group . ... Galaxies and Quasars . ... All galaxies emit radio waves as well as light. ... Often, they shoot out two jets, magnetic fields and very fast electrons (see below). ... This explains why we often see one very bright jet ? ... Quasars, the most powerful sources, often show a prominent jet, strong radio galaxies like the one to the right more usually don?t. The most powerful of these radio sources can be detected at immense distances in the Universe ? ...

... Now, think about a much bigger move: What do you think it would be like if the Earth moved to a different part of our Galaxy? Our Galaxy, the Milky Way, is shaped like a whirlpool: It has bands of stars that spiral around the centre, which astronomers call the Galaxy s arms . ... We live in the outer parts of the Milky Way, in one of its spiral arms. ... The small centre of the Milky Way is a much more crowded place, as this is where most of its stars are found. ...

Observations over the last decade indicate black-holes likely resided at the heart of most if not all galaxies. The correlation between the masses of these compact nuclear sources and their host galaxy is poorly understood and likely plays an important role in the formation and evolution, of at least the most massive systems, due to AGN feedback. ... I will give a brief summary of the reverberation mapping technique and describe the important role SkyMapper photometry can play in this program. ...

... We start with calculation of burst-like   star formation in a galaxy assuming all stars to have been formed simultaneously. ... In order to obtain the SN rate, we approximate the SFR in the Universe by a combination of two functions - a -like SFR of the ``first generation'' stars (presumably ``elliptical galaxies''   with no subsequent star formation) and a constant SFR of the second generation (``spiral galaxies''   with a constant star formation): . ...
