New exciting discovery by LIGO and Virgo!

LIGO and Virgo announce the discovery of a new gravitational-wave binary system. Read all about this exciting new event in the paper published today in The Astrophysical Journal Letters, coauthored by three IMAC researchers. For decades, astronomers have puzzled over a "mass gap" that lies between neutron stars and black holes. Now LIGO and Virgo have found an object that’s firmly in the mass gap.

New windows to the sky

Astrophysics and cosmology are the studies of the Universe. In recent years, two interconnected areas of research have moved to the forefront of these disciplines: Multi-messenger astrophysics and precision cosmology. The former studies high-energy celestial phenomena through complementary physical carriers such as electromagnetic waves, gravitational waves and cosmic rays. The latter studies the large-scale structure of the Universe to reveal its origin and fate. Together, multi-messenger astrophysics and precision cosmology allows scientists to unravel the deepest mysteries of the Universe, such as its origin and composition.
In the past few years, multi-messenger astrophysics and precision cosmology have exponentially grown in importance in the physics research community. The Institute of Multi-messenger Astrophysics and Cosmology (IMAC) plays a prominent role in these research areas, putting S&T at the center stage of modern astrophysical research.


Research and education

Multi-messenger astrophysics

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.

Education and outreach

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.
