Southern Hemisphere Calls for Gravitational Wave Observatory

A recent study highlights the need for a gravitational wave observatory in the Southern Hemisphere, as all active observatories are currently located in the Northern Hemisphere. Building a gravitational wave observatory in the Southern Hemisphere would not only broaden global participation but also provide significantly more observational data, especially considering the dense central region of our galaxy is in the Southern sky. Adding an Australian detector to the existing LIGO and Virgo detectors would double the number of detected events, allowing for triangulation and multi-messenger astronomy. Future advanced detectors with longer arms would further enhance detection capabilities, and having an observatory in Australia would provide a significant advantage in maintaining a consistent detection rate.
