Due to high stable rotations, timing of pulsars provides a natural tool to correct the frequency deviation of spaceborne atomic clocks. Based on processing the observational data about a year of Crab pulsar given by X...
FAST Detects over 500 New Pulsars Using the Five-hundred-meter Aperture Spherical Radio Telescope(FAST),also dubbed as the“China Sky Eye,”scientists have identified over 500 new pulsars since October 2017.FAST also ...
Pulsar Timing Arrays(PTAs),consisting of a collection of millisecond pulsars,are specifically designed to detect nanohertz gravitational waves[1].Recently,multiple PTA collaborations,including the North American Nanoh...

Several pulsar timing array(PTA)collaborations,including NANOGrav,EPTA,PPTA,and CPTA,have announced the evidence for a stochastic signal consistent with a stochastic gravitational wave background(SGWB).Supermassive bl...
It is hypothesized that,at low temperature,though atomic nuclei are made of 2-flavored nucleons(i.e.,nucleon matter as nuclear droplet),strongly interacting matter(i.e.,gigantic nucleus)with baryon number from A≃10^(3...
