Evading the CMB $μ$ -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 $z ≳ 6$ 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…
