The role of equation of state on the spin-up of millisecond pulsars
Xinyi Zhong, Xiaoyu Lai
Millisecond pulsars (MSPs) are recycled pulsars which have been spun-up due to mass accretion during the phase of mass exchange in binaries. Although the interactions with companio…

Model independent calibration for sound horizon combining observations of supernovae and transversal BAO measurements
Tonghua Liu, Xinyi Zhong, Jieci Wang +1
The sound horizon is a key theoretical prediction of the cosmological model that depends on the speed of sound and the rate of expansion in the early universe, before matter and ra…

Constraining on the non-standard cosmological models combining the observations of high-redshift quasars and BAO
Ziqiang Liu, Tonghua Liu, Xinyi Zhong +2
In this work, we studied four types of cosmological models with different mechanisms driving the accelerated expansion of the universe, include Braneworld models, Chaplygin Gas mod…
