Inspiraling binary charged black holes in an external magnetic field: Application of post-Newtonian dynamics in Einstein-Maxwell theory
RunDong Tang, Lang Liu, Wen-Biao Han
We present a systematic post-Newtonian treatment of binary charged black holes immersed in external magnetic fields within the framework of Einstein-Maxwell theory. By incorporatin…
Implications for the non-Gaussianity of primordial gravitational waves from pulsar timing arrays
Zhi-Zhang Peng, You Wu, Lang Liu
The detection of a stochastic signal by recent pulsar timing array (PTA) collaborations, including NANOGrav, PPTA, EPTA+InPTA, CPTA and MPTA, has opened a new window to explore gra…
Constraints on Pre-Big-Bang Cosmology from Advanced LIGO and Advanced Virgo's First Three Observing Runs
Qin Tan, Zu Cheng Chen, You Wu +1
We search for the stochastic gravitational-wave background (SGWB) predicted by pre-big-bang (PBB) cosmology using data from the first three observing runs of Advanced LIGO and Adva…
Pre-Big-Bang Cosmology Cannot Explain NANOGrav 15-year Signal
Qin Tan, You Wu, Lang Liu
We investigate whether the Pre-Big Bang (PBB) scenario from string cosmology can explain the stochastic gravitational wave background signal reported in the NANOGrav 15-year datase…
