What is NANOGrav?

NANOGrav is a collaboration of scientists working to detect and study gravitational waves — tiny ripples in the fabric of space and time.

Get to know NANOGrav

About this image: Clockwise from top left: NANOGrav members gather at the Arecibo Observatory; an artist's impression of a pulsar, an exotic object that we are using to search for gravitational waves; and the the Arecibo Observatory and the Green Bank Telescope, the two most important telescopes for NANOGrav.

Why study gravitational waves?

Gravitational wave astronomy is at the cutting edge of modern science and is about to open a whole new window on our Universe.

How does NANOGrav work?

We use exotic objects called pulsars to create a "cosmic global positioning system".

About this image: A schematic diagram of a pulsar timing array. NANOGrav uses this technique to detect the influence of gravitational waves on the Earth.

Who are we?

We are a diverse group of astronomers, physicists, and engineers comprised of senior scientists, postdoctoral fellows, and graduate and undergraduate students.

Meet the NANOGrav team

About this image: NANOGrav members gather for a group photo at our Fall 2012 meeting at Oberlin College.

Where can you find us?

NANOGrav members are located at over a dozen institutions throughout North America, and we collaborate with colleagues from around the world.

When will NANOGrav find gravitational waves?

We predict that we will detect gravitational waves within the next decade. But detection is only the first step towards ushering in a new era of gravitaional wave astronomy.

Explore a new frontier in astronomy

About this image: In this graph, solid lines represent the sensitivity of current and future gravitational wave experiments (regions above the lines can be detected). The shaded regions show the expected strength of gravitational waves from various sources according to different models. Pulsar timing arrays are towards the left, at the lowest frequencies, and are expected to make a detection of supermassive black holes or cosmic strings by no later than 2020.


Maura McLaughlin will give a lecture entitled "Building a Galactic Scale Gravitational Wave Observatory" at Penn State University in State College, PA for the American Physical Society Meeting


Congratulations to Justin Ellis and the rest of the NANOGrav team on the release of a new limit paper.

NANOGrav Limits on Gravitational Waves from Individual Supermassive Black Hole Binaries in Circular Orbits

NANOGrav held a Senior Personel meeting in Washington D.C. on December 16, 2013. An overview of our science and the status of our experiment was presented to the community. Here is the talk that was presented.
