Dive into the world of gravitational waves and radio bursts.
Sometimes astronomers observe intense bursts of radio waves from space that are only moments long, but release as much energy in a millisecond as the Sun does in a few years. The origin of these "fast radio bursts" remains one of the greatest mysteries of modern astronomy.
There are many theories that explain the cause of these spikes. Among them are highly magnetic neutron stars, collisions of incredibly dense stars, and many other extreme phenomena.
One way to test which theory is correct is to look for additional information about bursts using gravitational waves-fluctuations in the fabric of the universe.
A new study published in The Astrophysical Journal compared dozens of observations of fast radio bursts with data from gravitational wave telescopes to identify possible connections.
Gravitational waves pass directly through matter, so nothing can interfere with them. Astronomers have already detected gravitational waves from collisions of compact stellar systems such as black holes and neutron stars.
To look for new evidence of the causes of fast radio bursts, a targeted search was conducted using the CHIME radio telescope in Canada. Despite the fact that the CHIME/FRB project has detected hundreds of fast radio bursts, it has not yet been possible to detect a connection with gravitational waves.
The research team looked for gravitational waves in the region of the sky where fast radio bursts occurred. For non-repeating bursts, two types of search were performed: one that looked for known signals of gravitational waves, and another that looked for any burst of energy that was different from the usual one.
Results? This time, nothing was found. However, despite the lack of definite results this time, future searches may be a key step towards understanding fast radio bursts.
Gravitational wave detectors are becoming more sensitive, and their efficiency will continue to grow in the coming years. This will make it possible to conduct long-distance research in space and test a much larger volume of fast radio bursts.
