DECi-hertz Interferometer Gravitational-wave Observatory: Forecast constraints on the cosmic curvature with LSST strong lenses
Shuo Cao, Tonghua Liu, Marek Biesiada +3
In this paper, we aim at using the DECi-hertz Interferometer Gravitational-wave Observatory (DECIGO), a future Japanese space gravitational-wave antenna sensitive to frequency rang…
Revisiting the cosmic distance duality relation with machine learning reconstruction methods: the combination of HII galaxies and ultra-compact radio quasars
Tonghua Liu, Shuo Cao, Sixuan Zhang +3
In this paper, we carry out an assessment of cosmic distance duality relation (CDDR) based on the latest observations of HII galaxies acting as standard candles and ultra-compact s…
Dark photon bursts from compact binary systems and constraints
Shaoqi Hou, Shuxun Tian, Shuo Cao +1
In this work, we consider the burst signal of the dark photon, the hypothetical vector boson of the or gauge group, generated by a compact binary star system.…
Comparing the scalar-field dark energy models with recent observations
Tengpeng Xu, Yun Chen, Lixin Xu +1
We investigate the general properties of a class of scalar-field dark energy models (i.e., CDM models) which behave like cosmological trackers at early times. Particularly, we c…
Consistency testing for invariance of the speed of light at different redshifts: the newest results from strong lensing and type Ia supernovae observations
Tonghua Liu, Shuo Cao, Marek Biesiada +3
The invariance of the speed of light in the distant universe has profound significance for fundamental physics. In this paper, we propose a new model-independent method to test the…
Constraints on the abundance of supermassive primordial black holes from lensing of compact radio sources
Huan Zhou, Yujie Lian, Zhengxiang Li +2
The possibility that primordial black holes (PBHs) form a part of dark matter has been considered over a wide mass range from the Planck mass () to the level of the…
