Cosmological Standard Timers from Unstable Primordial Relics
Yi-Fu Cai, Chao Chen, Qianhang Ding +1
In this article we study a hypothetical possibility of tracking the evolution of our Universe by introducing a series of the so-called standard timers. Any unstable primordial reli…
Covariant transverse-traceless projection for secondary gravitational waves
Atsuhisa Ota, Hayley J. Macpherson, William R. Coulton
Second-order tensor modes induced by nonlinear gravity are a key component of the cosmological background of gravitational waves. A detection of this background would allow us to p…
Axi-Higgs cosmology: Cosmic Microwave Background and cosmological tensions
Hoang Nhan Luu
Non-canonical cosmology with an uplifted Higgs vacuum expectation value (Higgs-VEV) in the early universe is believed to provide the solution for existing tensions within the CD…
A Theory of Dark Pions
Hsin-Chia Cheng, Lingfeng Li, Ennio Salvioni
We present a complete model of a dark QCD sector with light dark pions, broadly motivated by hidden naturalness arguments. The dark quarks couple to the Standard Model via irreleva…
Primordial black holes and stochastic gravitational wave background from inflation with a noncanonical spectator field
Rong-Gen Cai, Chao Chen, Chengjie Fu
We investigate the enhancement of the curvature perturbations in a single-field slow-roll inflation with a spectator scalar field kinetically coupled to the inflaton. The coupling…
Ultrahigh-energy Gamma Rays and Gravitational Waves from Primordial Exotic Stellar Bubbles
Yi-Fu Cai, Chao Chen, Qianhang Ding +1
We put forward a novel class of exotic celestial objects that can be produced through phase transitions occurred in the primordial Universe. These objects appear as bubbles of stel…
Axion Isocurvature Collider
Shiyun Lu
Cosmological colliders can preserve information from interactions at very high energy scale, and imprint them on cosmological observables. Taking the squeezed limit of cosmological…
Axi-Higgs Cosmology
Leo WH Fung, Lingfeng Li, Tao Liu +3
If the electroweak Higgs vacuum expectation value in early universe is higher than its present value GeV, the Li puzzle in BBN and the CMB/CDM tens…
