SN 2015bf: a fast declining type II supernova with flash-ionised signatures
Han Lin, Xiaofeng Wang, Jujia Zhang +19
We present optical and ultraviolet photometry, as well as optical spectra, for the type II supernova (SN) 2015bf. Our observations cover the phases from to d af…
Intermittent null energy condition violations during inflation and primordial gravitational waves
Yong Cai, Yun-Song Piao
Primordial null energy condition (NEC) violation would imprint a blue-tilted spectrum on gravitational wave background (GWB). However, its implications on the GWB might be far rich…
Trans-Planckian censorship of multistage inflation and dark energy
Hao-Hao Li, Gen Ye, Yong Cai +1
We explore the bound of the trans-Planckian censorship conjecture on an inflation model with multiple stages. We show that if the first inflationary stage is responsible for the pr…
Pre-inflation and Trans-Planckian Censorship
Yong Cai, Yun-Song Piao
We investigate the implication of Trans-Planckian Censorship Conjecture (TCC) for the initial state of primordial perturbations. It is possible to set the state of perturbation mod…
Perturbative Reheating in Sneutrino-Higgs Cosmology
Yong Cai, Rehan Deen, Burt A. Ovrut +1
The theory of perturbative reheating in the Sneutrino-Higgs cosmology of the MSSM is presented. It is shown that following an epoch of inflation consistent with all Planck201…
The effective field theory approach of teleparallel gravity, gravity and beyond
Chunlong Li, Yong Cai, Yi-Fu Cai +1
We develop the effective field theory approach to torsional modified gravities, a formalism that allows for the systematic investigation of the background and perturbation levels s…
