Kinetically stabilized inflation
Changhong Li, Hao Gong, Yeuk-kwan Edna Cheung
In this work, we propose a string-inspired two fields inflation model to address the fine-tuning problem that the standard inflation model suffers. The fast-rolling tachyon $\mathc…
Influence of the correlation prior on reconstruction of the dark energy equation of state
Youhua Xu, Hu Zhan, Yeuk-Kwan Edna Cheung
Non-parametric reconstruction of the dark energy equation of state (EoS) aims to determine the EoS as a function of redshift without invoking any particular dark energy model, so t…
Reconstructing the Cosmic Expansion History with a Monotonicity Prior
Youhua Xu, Hu Zhan, Yeuk-Kwan Edna Cheung
The cosmic expansion history, mapped by the Hubble parameter as a function of redshift, offers the most direct probe of the dark energy equation of state. One way to determine the…
Big Bounce Genesis and Possible Experimental Tests -- A Brief Review
Yeuk-Kwan E. Cheung, Changhong Li, J. D. Vergados
We review the recent status of big bounce genesis as a new possibility of using dark matter particle's mass and interaction cross section to test the existence of a bounce universe…
