A Young Pulsar in the Galactic Halo: Clues to Its Origin and Scintillation

The researchers challenging the long-held view that pulsars are predominantly born in the disk. By precisely measuring its motion across the sky and analyzing the “scintillation” of its radio signal, researchers find that this object m...A young pulsar located far from the Galactic disk, in the Galactic halo, is challenging the long-held view that pulsars are predominantly born in the disk. By precisely measuring its motion across the sky and analyzing the “scintillatio...

Tracking activities of the Universe’s Most Energetic Galaxies with Urumqi NanShan 26 m Radio Telescope

Researchers have unveiled long-term radio data from some of the universe’s most extreme galaxies: gamma-ray-loud active galactic nuclei (AGNs). A research team led by Prof. CUI Lang at the Galaxy and Cosmology Group of Xinjiang Astronomical Observatory (XAO), Chinese Academy of Sciences (CAS)—including Krishna Mohana A, WANG Xin, CHANG Ning , TAN Guiping , and LIU Xiang—has un...

Research Ucovers Long-Term Pulsation Evolution in the δ Scuti Variable Star KIC 8712760

The researchers conducted a long-term observational study on the δ Scuti variable star KIC 8712760. Their work revealed a significant evolution of the star's pulsation amplitude over time. Stars are not eternally quiet and unchanging celestial bodies; some stars periodically brighten and dim. Astronomers refer to this phenomenon as stellar pulsation. Studying these pulsations is like performing an "ultrasound examination" ...

How do the ultra-long period radio pulsars differ from normal pulsars?

The resaerchers investigate the emission properties in 10 ULRa-TPs against that of 100 FAST normal pulsars based on their emission geometry and several emission correlations well-known to radio pulsars.We ask the question: To what extent do ultra‑long period radio pulsars and transients (ULRa-TPs) differ from conventional radio pulsars? It is apparent that they rotate very slowly, but do they also behave differently in the emission ph...

A Rapid Spin-down Millisecond Pulsar Puts Stringent Constraints on Classical Theory of Millisecond Pulsar Formation

The researchers conducted deep observations of the newly discovered millisecond pulsar PSR J0435+3233 with abnormally high spin-down rate.A research team led by Prof. WANG Na from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences (CAS) conducted in-depth observations of PSR J0435+3233 using the Five-hundred-meter Aperture Spherical radio Telesc...
