Those lost at sea
No full textThis photograph originally appeared in the 2014 Research student photography and image competition held to celebrate National Science Week (Aug 16-24). Blurb: In 2001, 353 asylum seekers, mainly women and children, drowned on their way to Christmas Island. Known as the SIEV X incident, in the tragedy's aftermath the Howard government refused to release the names of the deceased. On Christmas Island, a memorial was built by the local community to acknowledge the victims. Islanders painted the names of the dead on the rocks that surround the memorial to ensure that those lost at sea were never forgotten.

The devil is in the details

Part of the Big Data problem in astrophysics is to store large surveys' data files within the limited storage space available. A solution I investigate is the use of lossy data compression, which shrinks the size of the files. The resulting file is an approximation of the original one. From mobile phone to high-definition television, lossy compression is widely used in the world around us. However, when used within scientific research, lossy compression may lead to wrong analysis results. I evaluate how far we can push this loss of information so we can still thrust our analysis. Here, I show slight differences in the data that are almost not noticeable to the human eye, but noticeable numerically.
The nearly identical images are cosmological microlensing magnification maps. Quasar microlensing is the gravitational lensing effect of stellar mass objects within foreground galaxies that lie along the line of sight to multiply-imaged background quasars. Magnification maps are pixelated versions of the caustic pattern in the background source plane created by the foreground microlenses. By using these maps, it is possible to compare models of quasar structure to observations.
Left image is a magnification map using 400 megabytes (MB) of storage space. Centre image is a compressed map using 0.4 MB. When we subtract the compressed map from the original map (like 2-1=1), we get a residual map showing the differences between the approximated and the original values in the image. The residual is shown on the far right.

The team work

Blurb: At the very first glance, the image does not seem very related to research or whatever around it. But I found the team work in this image quite inspiring. Though the goal is so huge and unattainable, the coordination and the effort is still the same. It reminds me of the efforts in engineering teams (specifically my own interest: Software Engineering) while conducting massive projects
Radio astronomy

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 predict 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
