A new study released today makes a compelling case for the development of “NEMO”\u2014a new observatory in Australia that could deliver on some of the most exciting gravitational-wave science<\/a> next-generation detectors have to offer, but at a fraction of the cost.<\/p>\n

\n <\/section>\n

The study, co-authored by the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav), coincides with an Astronomy Decadal Plan mid-term review by Australian Academy of Sciences where “NEMO” is identified as a priority goal.<\/p>\n

“Gravitational-wave astronomy is reshaping our understanding of the universe,” said one of the study’s lead authors ARC Future Fellow, Dr. Paul Lasky, from the Monash University School of Physics and Astronomy, and OzGrav.
\n“Neutron stars are an end state of stellar evolution,” he said.
\n“They consist of the densest observable matter in the universe, and are believed to consist of a superfluid, superconducting core of matter at supranuclear densities. Such conditions are impossible to produce in the laboratory, and theoretical modeling of the matter requires extrapolation by many orders of magnitude beyond the point where nuclear physics is well understood.”
\nThe study today presents the design concept and science case for a Neutron Star Extreme Matter Observatory (NEMO): a gravitational-wave interferometer optimized to study nuclear physics with merging neutron stars.
\nThe concept uses high circulating laser power, quantum squeezing and a detector topology specially designed to achieve the high frequency sensitivity necessary to probe nuclear matter using gravitational waves.
\nThe study acknowledges that third-generation observatories require substantial, global financial investment and significant technological development over many years.
\nAccording to Monash Ph.D. candidate Francisco Hernandez Vivanco, who also worked on the study, the recent transformational discoveries were only the tip of the iceberg of what the new field of gravitational-wave astronomy could potentially achieve.
\n“To reach its full potential, new detectors with greater sensitivity are required,” Francisco said.
\n“The global community of gravitational-wave scientists is currently designing the so called ‘third-generation gravitational-wave detectors (we are currently in the second generation of detectors; the first generation were the prototypes that got us where we are today).”
\nThird-generation detectors will increase the sensitivity achieved by a factor of 10, detecting every black hole merger throughout the universe, and most of the neutron star collisions.
\nBut they have a hefty price tag. At about $1B, they require truly global investment, and are not anticipated to start detecting ripples of gravity until 2035 at the earliest.
\nIn contrast, NEMO would require a budget of only $50 to $100M, a considerably shorter timescale for development, and it would provide a test-bed facility for technology<\/a> development for third-generation instruments.
\nThe paper today concludes that further design studies are required detailing specifics of the instrument, as well as a possible scoping study to find an app<\/a>ropriate location for the observatory, a project known as “Finding NEMO.”<\/p>\n
