Jenet’s group thinks that anomalous dispersion should be added to this list. Using the Arecibo Observatory in Puerto Rico, they took radio data of the pulsar PSR B1937+21 at 1420.4 MHz with a 1.5 MHz ...

An international team of astronomers reports the detection of the first pulsar by the Globular Clusters ... Das of the National Center for Radio Astrophysics (NCRA) in India, reports the first ...

The pulsar has a spin period of 33.16 milliseconds and a dispersion measure of approximately 24.93 pc/cm 3. Previous observations of M53A have found that it is a binary system with an orbital ...

The property the researchers examined is known as the dispersion measure, one of the key attributes of pulsars and fast radio bursts.It refers to how much a tightly pulsed beam of radio light is ...

The surprising detection of light 200 times more powerful than previous observations from the nearby pulsar Vela indicates hidden physics around dead stars. When you purchase through links on our ...

Comparison of traditional velocity dispersion and pulsar timing methods (left) versus the HiVel ejection from globular clusters method (right) in the search for IMBHs.

Named as PSR J1717+4307A or M92A, it is the first pulsar known in M92, with a spinning period of 3.16 ms and a dispersion measure ... Milky Way and of related astrophysics, such as massive ...

Pulsar timing leverages observations of ultra-stable cosmic clocks known as pulsars to probe fundamental physics, from tests of alternate theories of gravity to constraints of extreme nuclear physics ...
