Constraints on Axion-like Dark Matter from Cosmic Birefringence with a Polarization Array of Repeating Fast Radio Bursts
Xiaohui Liu, Zi-Yan Yuwen, Yun-Long Zhang +5
Axion-like dark matter (ALDM) is a well-motivated dark matter candidate whose Chern-Simons coupling to photons can induce cosmic birefringence, producing temporal oscillations and…
Probing Baryonic Feedback Effect with CSST Weak Lensing and Future FRB Measurements
Shuai Feng, Yan Gong, Qi Xiong +4
We explore the joint probe on the baryonic feedback effect using the weak lensing measurement from the upcoming Chinese Space-station Survey Telescope (CSST) photometric survey and…
Inferring the Intrinsic Energy Function of FRB 20220912A
Xiaohui Liu, Wei-Yang Wang, Weicong Jing +2
The statistical analysis of fast radio burst (FRB) samples from repeaters may suffer from a band-limited selection effect, which can bias the observed distribution. We investigated…
Constraining and Comparing the Dynamical Dark Energy and f(R) Modified Gravity Models with Cosmological Distance Measurements
Shuai Feng, Yan Gong, Xiaohui Liu +2
We constrain and compare the CDM dynamical dark energy model and three modified gravity models using the current cosmological distance measurements, including 11…
