Evading the CMB -distortion bound on Supermassive Primordial Black Hole seeds with Non-Gaussian tails
Sanket Dave, Sheng-Feng Yan, Amara Ilyas +1
Supermassive black holes (SMBHs) powering quasars at are difficult to grow from stellar mass remnants, motivating seeds from primordial black holes (PBHs) with masses…
Do We Have Sufficient Knowledge of the Galactic Foreground Emission in Cosmic Microwave Background Science?
Jia-Rui Li, Peibo Yuan, Yi-Fu Cai +1
Galactic foreground emission plays a key role in cosmic microwave background (CMB) science, particularly for detecting primordial gravitational waves. A well-known lesson is the ``…
Smoking-gun signatures of bounce cosmology from echoes of relic gravitational waves
Mian Zhu, Yi-Fu Cai
We report a novel feature of relic gravitational waves (GWs) in non-singular bounce cosmologies that is testable in light of GWs astronomy. In non-singular bounce cosmologies, the…
Space-based optical lattice clocks as gravitational wave detectors in search for new physics
Bo Wang, Bichu Li, Qianqian Xiao +2
We investigate the sensitivity and performance of space-based Optical Lattice Clocks (OLCs) in detecting gravitational waves, in particular the Stochastic Gravitational Wave Backgr…
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)…
Implications of scattering for CMB foreground emission modelling
Jia-Rui Li, Jacques Delabrouille, Yi-Fu Cai +1
Context. The extreme precision and accuracy of forthcoming observations of CMB temperature and polarization anisotropies, aiming to detect the tiny signatures of primordial gravita…
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…
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…
Parametric resonance of gravitational waves in general scalar-tensor theories
Yi-Fu Cai, Guillem Domènech, Alexander Ganz +3
Gravitational waves offer a potent mean to test the underlying theory of gravity. In general theories of gravity, such as scalar-tensor theories, one expects modifications in the f…
