... 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. ... The color figure below shows the HI emission (blue) in the bridge velocity range overlaid onto an optical image. ... A tidal HI bridge is visible between NGC 6221 and its brightest neighbour, NGC 6215 (v_sys = 1555 km/s). ...

... Our recent observations with the Hubble Space Telescope (August 29, 2014) led to revealing a highly isolated dwarf spheroidal galaxy KKs 3 situated at a distance of 2.12 0.07 Mpc from the Milky Way.

Time has come for me to move to a new longitude, but not before following the tradition and updating you on the work I have been doing in the latest stages of my PhD (and beyond). ... This presentation would of course not be complete without a final attempt at convincing you of the potential of some excitingly new technology to publish multi-dimensional datasets in 3-D. Hence, I shall also tell you about the newly developed X3D pathway Chris Owen and I have been developing lately. ...

Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...
