Radio astronomy

Abstract:

Description: This photograph originally appeared in the 2014 Research student photography and image competition held to celebrate National Science Week (Aug 16-24). Blurb: I am using large antennas to observe very faint radio signals originating from hydrogen gas in distant galaxies. Stars are formed from hydrogen and by observing the hydrogen content in a galaxy I can pbkp_redict how much longer a galaxy is able to form stars. I took this photo in January 2013 at The Australia Telescope Compact Array in Narrabri (NSW) while I was observing some galaxies. The Compact Array is a radio telescope consisting of 6 individual 22 meter antennas. Linked together these 6 antennas equal a telescope that would be 6 kilometres in diameter. Another great thing about radio telescopes is that we can observe with them 24 hours, even during the day and even when it is overcast or raining.
