      New model for explaining X-ray bursts
      The researchers proposed a new model to explain the phenomenon of repeated X-ray bursts. By simulating and analyzing, they successfully explained the main features of the observed X-ray bursts, including energy, duration, periodicity, an...The interaction between neutron stars and their surrounding objects has been a hot topic in astronomy. In recent years, scientists have observed repeated X-ray bursts from the galactic magnetars SGR 1806-20 and SGR 1935+2154, which exhib...

      New study reveals microstructure of the interstellar medium from pulsar scintillation
      The reserchers employed radio observations of pulsars to detect these complex microstructures using the interstellar scintillation effect. This study utilized the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in China and ...The microstructure of the interstellar medium has been a hot topic of research in modern astrophysics. The turbulence and small-scale structures within the interstellar medium have profound implications for understanding the structure an...

      Researchers using multi-phase-center VLBI observations reveal pc-scale radio emission properties of dual AGNs
      Galaxy mergers play a crucial role in the cosmological evolution of galaxies. During galaxy merging, tidal torques can trigger the accretion and feedback of the central black holes in merging galaxies, forming dual active galactic nuclei...Galaxy mergers play a crucial role in the cosmological evolution of galaxies.

      Emission geometry and jitter noise in millisecond pulsars
      In an ideal world, pulses from radio pulsars arrive regularly. However, this is not always the case, and the closest to that is probably the millisecond pulsars (MSPs). As the name suggests, these pulsars have very short rotation periods...In an ideal world, pulses from radio pulsars arrive regularly.
