A New Finding Reveals New Clues to Pulsar Interior–Magnetosphere Coupling

By analyzing the long-term timing data obtained with the Nanshan 25 m radio telescope from 2002 to 2014 and the publicly available international datasets, a research team from the Xinjiang Astronomical Observatory, Chinese Academy of Sci...Pulsars are rapidly rotating neutron stars with exceptionally stable spin rates, making them veritable "cosmic clocks" in the universe. However, some pulsars undergo sudden "glitches"—abrupt spin-up events followed by a gradual recovery...

A Fossil Bubble in the Milky Way Reveals a Relay of Star Formation

The researchers conducted a study on G35.28+0.04, a giant ring-like molecular gas structure in the Milky Way. They found that this structure may record a "relay race" of star formation that has lasted for tens of millions of years. The r...Massive stars play a key role in the interstellar medium cycle, molecular cloud evolution, and star formation. Through ultraviolet radiation, stellar winds, and even supernova explosions, massive stars continuously influence the surround...

Time-Variable Periodic Nulling Revealed in PSR B0751+32

The researchers conducted high-sensitivity observations of pulsar B0751+32, capturing the time-variable nature of its periodic nulling. The study reveals that the nulling period varies significantly between different observing epochs an...Radio emission of some pulsars occasionally ceases suddenly during certain rotation periods, a phenomenon known as "pulsar nulling." When this silence follows a regular, repeating pattern, it is called periodic nulling. Earlier models su...

New Findings Reveal A Pulsar Exhibits Three Distinct Emission Variations

Using observational data from Australia’s Parkes 64-meter Radio Telescope, the researchers collected and meticulously analyzed over ten thousand single pulses, confirming that a single pulsar can host three unique emission behaviors at ...Pulsars in space act like rotating cosmic lighthouses, continuously emitting regular radio signals. PSR J0846−3533 is exceptional, as it displays three entirely different emission variations simultaneously, a phenomenon that had never b...

New VLBI Observation Reveals a Rare, Compact, Fading Jet in an Intermediate-Mass Black Hole Merger System

The researchers conducted a dedicated study of the nearby dwarf galaxy merger system SDSS J101747.09+393207.7 (also known as RGG66), and providing new clues for understanding how galaxy mergers trigger black hole accretion and black hole...Intermediate-mass black holes (IMBHs, ~10² - 10⁶ M☉) bridge the gap between stellar-mass and supermassive black holes. They are crucial for understanding key scientific questions, such as the growth of black hole mass and the co-evolu...

Cosmic Duet：When a Pulsating Star Meets Tidal Locking

The researchers has unveiled the secrets of this system using data from NASA’s TESS space telescope and ground-based observations.About 467 light-years away, a stellar system designated TIC 197757000 is performing a cosmic dance—two stars orbiting each other every 2.2 days. Now, a team led by Ph.D. student Shahidin Yaqup and his supervisor Prof. Ali Esamdin at the...
