A Single Pulse Study of a Millisecond Pulsar PSR J0621+1002

Millisecond pulsars (MSPs) are characteristic by their stable rotations. It is possible to detect nanohertz gravitational waves by monitoring pulse times of arrival (ToAs) of an ensemble of the most stable MSPs. The success of this exper...

Research in the radio/X-ray correlation of hard X-ray selected Seyfert galaxies sample

Almost every galaxy contains a supermassive black hole (SMBH) at its centre. The SMBH will become active when surrounding material is captured by the black hole (BH) gravitational potential well, forming an accretion disc and emitting mu...

FAST detected the three-dimensional spin-velocity alignment in a pulsar

Dr. YAO Jumei and a team of astronomers have conducted an investigation based on FAST observation that led to the discovery of the first evidence for three-dimensional (3D) spin-velocity alignment in pulsars. Pulsar, rotating neutron sta...

Evolution of LMXBs under Different Magnetic Braking Prescriptions

MB plays a vital role in LMXB evolution; however, its mechanism has not been well understood. The traditional MB law faces difficulties in explaining the observational characteristics of LMXBs and MSPs, such as the discrepancy between th...

The Progress in Studies of Carbon-rich Type Ia supernova SN 2017hpa

Type Ia supernovae (SN Ia) are widely believed to originate from thermonuclear explosions of carbon-oxygen white dwarfs, and their essentially identical peak luminosities make them indicators of extra-galactic distances and important pro...

Extended HNCO, SiO, and HC3N Emission in 43 Southern Star-forming Regions

Shocks are a ubiquitous phenomenon in the interstellar medium (ISM) of galaxies. They may be driven by supernova explosions, the pressure of photoionized gas, stellar winds, and collisions between fast-moving clumps of interstellar gas, ...
