Constraints on Buchdahl-Inspired Gravity from Future Pulsar Timing near Sgr A*

Jian-Ming Yan, Tao Zhu, Zong-Kuan Guo +1

Future pulsar timing observations near Sgr~A* offer a unique probe of gravitational physics in the vicinity of a supermassive black hole. We forecast the ability of such measuremen…

Double-layered vacuum bubbles and cosmological phase transitions

Dongdong Wei, Zong-Kuan Guo, Qiqi Fan

We investigate the evolution and formation of double-layered vacuum bubbles during cosmological phase transitions with multiple vacua. We employ lattice simulations to show that fl…

Distinguishing gravity theories with networks of space-based gravitational-wave detectors

Bo Mu, Zong-Kuan Guo

We propose a method for separating and detecting the non-tensor modes of stochastic gravitational-wave backgrounds (SGWBs) using networks of space-based gravitational-wave detector…

Parameter inference for coalescing massive black hole binaries using deep learning

Wen-Hong Ruan, He Wang, Chang Liu +1

In the 2030s, a new era of gravitational-wave (GW) observations will dawn as multiple space-based GW detectors, such as the Laser Interferometer Space Antenna, Taiji and TianQin, o…

Particle production during Inflation with a non-minimally coupled spectator scalar field

Zhe Yu, Chengjie Fu, Zong-Kuan Guo

We study the inflationary model with a spectator scalar field coupled to both the inflaton and Ricci scalar. The interaction between the field and the gravity, denoted by $…

On networks of space-based gravitational-wave detectors

Rong-Gen Cai, Zong-Kuan Guo, Bin Hu +7

The space-based laser interferometers, LISA, Taiji and TianQin, are targeting to observe milliHz gravitational waves (GWs) in the 2030s. The joint observations from multiple space-…
