Using NASA's NuSTAR and Swift space observatories, Indian astronomers have inspected an X-ray pulsar known as XTE J1858+034 during its outburst and identified a low-frequency quasi-periodic oscillation (QPO) from this source. ...
Using data from the Rossi X-ray Timing Explorer (RXTE) satellite, astronomers from the Florida Institute of Technology have discovered a quasi-periodic oscillation (QPO) in the galaxy NGC 4945. The finding, reported in a ...
Astronomers from Australia and Taiwan report the discovery of millihertz quasi-periodic oscillations in a neutron-star low-mass X-ray binary known as 1RXS J180408.9−342058. The discovery, detailed in a paper published September ...
One fundamental problem of quantum electrodynamics is the fate of the superheavy atomic nucleus, which is proposed to collapse when the atomic number exceeds certain value. However, this intriguing supercritical collapse ...
