Implications of Cosmic Birefringence for Multi-Field ALP Dark Matter
Jialiang Shao, Ippei Obata, Dongdong Zhang
Cosmic birefringence, characterized by the observed rotation of the polarization plane of the cosmic microwave background (CMB) radiation, serves as a critical probe for testing th…
A Compaction Function Analysis of CMB distortion Constraints on Primordial Black Holes
Junyue Yang, Xiaoding Wang, Xiao-Han Ma +4
Primordial black holes (PBHs) are considered viable candidates for dark matter and the seeds of supermassive black holes (SMBHs), with their fruitful physical influences providing…
Constraining Ultralight ALP Dark Matter in Light of Cosmic Birefringence
Dongdong Zhang, Elisa G. M. Ferreira, Ippei Obata +1
Cosmic birefringence, the observed rotation of the polarization plane of the cosmic microwave background (CMB), serves as a compelling probe for parity-violating physics beyond the…
Constraints on large-scale polarization in northern hemisphere
Dongdong Zhang, Bo Wang, Jia-Rui Li +2
Present cosmic microwave background (CMB) observations have significantly advanced our understanding of the universe's origin, especially with primordial gravitational waves (PGWs)…
Ultra-light dark matter with non-canonical kinetics reopening the mass window
Shiyun Lu, Amara Ilyas, Xiao-Han Ma +3
Fuzzy dark matter (FDM) with mass around eV is viewed as a promising paradigm in understanding the structure formation of the local universe at small scales. Recent obse…
Constrain the linear scalar perturbation theory of Cotton gravity
Pengbo Xia, Dongdong Zhang, Xin Ren +2
We perform a cosmological test of Cotton gravity, which describes gravity by cotton tensor. We assume in Cotton gravity the background evolution is the same as the flat FLRW backgr…
A narrow-band parameterization for the stochastic gravitational wave background
Tianyi Xie, Dongdong Zhang, Jie Jiang +3
In light of the non-perturbative resonance effects that may occur during inflation, we introduce a parametrization for the power spectrum of the stochastic gravitational wave backg…
