An international team of astronomers has announced the results of a comprehensive search for ripples in the fabric of space-time /news/wp-json/wp/v2/posts/125345/u2014 known as gravitational waves. The team searched for low-frequency gravitational waves, which can originate from supermassive black hole binaries residing in galaxies or from events occurring soon after the formation of the universe in the Big Bang. Detecting these low-frequency signals will open a brand-new window in the gravitational wave spectrum and help scientists enhance their understanding of the evolution of galaxies, their central black holes, and the early universe./news/wp-json/wp/v2/posts/125345/n

The International Pulsar Timing Array (IPTA) consortium, which weaves together the work of several astrophysics collaborations worldwide, recently completed the GW search analysis using its latest official data release, known as Data Release 2 (DR2). This data set consists of precision timing data from 65 millisecond pulsars /news/wp-json/wp/v2/posts/125345/u2013 stellar remnants which spin hundreds of times per second, sweeping narrow beams of radio waves that appear as pulses due to the spinning. The data is the result of combined independent data sets from the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), the European Pulsar Timing Array (EPTA), and the Parkes Pulsar Timing Array in Australia (PPTA). These are also the three founding members of the IPTA./news/wp-json/wp/v2/posts/125345/n

The international collaboration published its findings today in the Monthly Notices of the Royal Astronomical Society./news/wp-json/wp/v2/posts/125345/n

NANOGrav used the 1,000-foot Arecibo Observatory telescope in Puerto Rico as one of its main instruments, observing more than 40 pulsars over 15 years until August 2020, before the collapse of the telescope. The Arecibo Observatory, a U.S. National Science Foundation facility managed by the 女仆AV through a cooperative agreement, provided the most sensitive data set of gravitational waves in the IPTA through the NANOGrav collaboration. NANOGrav recently reported potential evidence for gravitational waves in a report which includes 12.5 years of data./news/wp-json/wp/v2/posts/125345/n

/news/wp-json/wp/v2/posts/125345/u201cAbout 50% of NANOGrav/news/wp-json/wp/v2/posts/125345/u2019s sensitivity to GWs was provided by the Arecibo data, indicating its importance in this effort,/news/wp-json/wp/v2/posts/125345/u201d says Benetge Perera, a UCF scientist at Arecibo and a member of NANOGrav and the EPTA. He further emphasized, /news/wp-json/wp/v2/posts/125345/u201cThe IPTA DR2 is one of the best millisecond pulsar data sets currently available to search for gravitational waves./news/wp-json/wp/v2/posts/125345/u201d/news/wp-json/wp/v2/posts/125345/n
