Users can search across the full text of all the titles on Law Trove and search results bring up relevant chapters as well as whole textbooks.Individual textbook titles are searchable in iDiscover and links go directly to the relevant book on the Law Trove platform. The platform is listed on the ebooks LibGuide and in the Databases A-Z. "With these lenses at different distances, we can look at different points in the cosmic timeline to track how things change over time, between the very first galaxies and now," Tran said.Law Trove can be accessed by any member of the university using your Raven username and password. The average redshift of the lenses is 0.58, which corresponds to a distance of about 5 billion light-years, whereas the faraway objects that are being magnified by the lenses are typically at redshifts of about 1.92, meaning their light set out about 10 billion years ago. "Our goal … is to spectroscopically confirm around 100 strong gravitational lenses that can be observed from both the Northern and Southern hemispheres throughout the year," she said. The algorithm's 88% success rate in finding new lenses means there are now potentially thousands of new lenses for astronomers to choose from, though Tran said the team's aim was more modest. The lenses are typically at higher redshifts than most previously known lenses, meaning that astronomers can see deeper into the universe with them. They found 68 of these lenses to be real, and spectroscopically confirmed the redshifts of both the lens and the object being lensed for 53 of them. Keck Observatory in Hawaii and the Very Large Telescope in Chile to follow up on 77 of the 5,000 candidate lenses. Tran and her team used the telescopes at the W. 'These lenses are very small, so if you have fuzzy images, you're not going to really be able to detect them," Tran said in a statement (opens in new tab). The algorithm, developed by Colin Jacobs of the Swinburne University of Technology in Australia, sifted through tens of millions of galaxy images to select a sample of 5,000 candidate gravitational lenses that are not immediately obvious to the human eye.
