Using a set of ground-based radio telescopes, an international team of astronomers has observed a slowly-spinning pulsar ...
Dark matter, though invisible, weighs heavily on how we understand the universe. Its gravity sculpts galaxies, holds clusters ...
But none of the pulsar timing groups has yet reported 5-sigma results. China’s research team is the closest, with a confidence level of 4.6-sigma — which translates into a 2-in-a-million ...
Scientists have been using these cosmic clocks in experiments called Pulsar Timing Arrays. By searching for tiny deviations in the times at which the pulses arrive, scientist have been able to ...
The pulsar timing measurements must be extremely precise to measure the gravitational wave background correctly. The results from this study will help better model the distortions caused by DISS ...
Daniel J. Reardon et al, The neutron star mass, distance, and inclination from precision timing of the brilliant millisecond pulsar J0437-4715, arXiv (2024). DOI: 10.48550/arxiv.2407.07132 ...
However, to date, no timing solution for this pulsar has ever been published. That is why a team of astronomers led by Yujie Lian of the Beijing Normal University in China decided to investigate ...
What's a pulsar and why does it have a shock wave? Our observations honed in on the nearby fast-spinning pulsar, J0437-4715, which is 512 light-years away from Earth.
Discovering plasma structures in the Local Bubble with powerful radio telescopes challenges existing theories of interstellar ...
This "pulsar timing array" could detect the times at which radio pulses arrived to within a millionth of a second. The most likely sources of the newfound gravitational waves are pairs of ...
They were ripples discovered in association with collections of rapidly spinning neutron stars called "pulsar timing arrays." This low-frequency background hum of gravitational waves in our ...
