The LIGO Scientific Collaboration (LSC) and the Virgo Collaboration announced earlier today the detection of the most massive black hole merger yet observed in gravitational waves. The two merging black holes had a mass of about 85 and 66 times the mass of the sun and merged into a black hole with a mass of about 150 times that of the sun, releasing the energy of about eight suns. The two black holes were located roughly 15 billion light years away from Earth, making this event one of the most distant gravitational-wave sources detected so far. The international team of scientists have reported their findings in a Physical Review Letters paper, detailing the discovery, and a The Astrophysical Journal Letters paper, discussing the signal’s physical properties and astrophysical implications. Three IMAC researchers and students are among the authors of the two papers. Read LIGO-Virgo's press release.
The last decade has seen the birth of multi-messenger astrophysics. In the years to come, optical, particle and gravitational-wave astronomy will continue to explore the cosmos and redefine our understanding of the universe. IMAC is part of this new, exciting branch of science.
The origin and dynamics of the cosmic acceleration is a central problem of fundamental physics. IMAC researchers work to shed light on this problem and understand the nature of dark matter and dark energy.
IMAC formal and informal educational initiatives aim at promoting science in the Missouri community and bringing the wonder and excitement of scientific discovery to audiences of all ages and backgrounds.
