Imaging techniques III:
the Large Magellanic Cloud
by Bärbel Koribalski (CASS)
The two images above show the neutral
hydrogen (HI) distribution of the Large Magellanic Cloud (LMC), a close
neighbour of our Milky Way, using data from the Australia Telescope
Compact Array (ATCA) on the left and a combination of Parkes and ATCA HI
data on the right. An interferometer - like the ATCA - acts like a filter.
In particular, the very extended HI emission is not observed due to missing
short spacings, but is recovered by adding HI data from the 64-m Parkes
telescope. - Participants of this week's Radio
Synthesis School in Narrabri are learning all about interferometric
imaging techniques.
