New Study Suggests Pulsing Ultraluminous X-ray Sources Are Unlikely Origins of Periodically Active Fast Radio Bursts

A team conducted deep radio observations of eight pulsing ultraluminous X-ray sources (PULXs) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China and the Parkes radio telescope (Murriyang) in Australia, search...In the vast cosmos, fast radio bursts (FRBs) remain one of the most mysterious astrophysical phenomena ever discovered. These intense, millisecond-duration radio pulses can release in the radio band alone as much energy as the Sun emits ...

Researchers Reveal Complex Emission Geometry in Pulsars with Interpulses

new insights into the emission geometry of pulsars by analyzing a rare population of sources that exhibit interpulse radiation.Using the data obtained by the Five-hundred-meter Aperture Spherical radio Telescope (FAST), a research team at the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) has unveiled new insights into the emiss...

Researchers Unveil Axion-Torsion Coupling via Dark Photons

Researchers discovered a special effect induced by dark photons within the framework of the Einstein–Cartan–Holst theory for the first time. They also determined a key physical parameter—the BI parameter.A large portion of the universe is filled with invisible matter known as dark matter, and the dark photon is one of its leading theoretical candidates. As a hypothetical particle beyond the Standard Model, the dark photon exhibits electr...

Unveiling the Birth of Star Cluster Groups in the Milky Way

researchers have discovered four previously unrecognized primordial OC groups in the Milky Way.While star formation is generally understood to occur in a clustered mode, giving rise to open clusters (OCs), it remains an open question whether OCs predominantly form in isolation or also as part of larger, structured groupings.Recent...
