Primordial Non-Gaussianity from G-inflation
Fengge Zhang, Yungui Gong, Jiong Lin +2
Enormous information about interactions is contained in the non-Gaussianities of the primordial curvature perturbations, which are essential to break the degeneracy of inflationary…
Spatially covariant gravity with a dynamic lapse function
Jiong Lin, Yungui Gong, Yizhou Lu +1
In the framework of spatially covariant gravity, it is natural to extend a gravitational theory by putting the lapse function and the spatial metric on an equal footin…
Gauge transformation of scalar induced tensor perturbation during matter domination
Arshad Ali, Yungui Gong, Yizhou Lu
We study the scalar induced tensor perturbations at second order during matter domination in seven different gauges. Considering the obtained solution from the Newtonian gauge, we…
On the waveform of the scalar induced gravitational waves
Fengge Zhang, Arshad Ali, Yungui Gong +2
The scalar induced gravitational waves (SIGWs) is a useful tool to probe the physics in the early universe. To study inflationary models with this tool, we need to know how the wav…
Gauge transformation of scalar induced gravitational waves
Yizhou Lu, Arshad Ali, Yungui Gong +2
The gauge dependence of the scalar induced gravitational waves (SIGWs) generated at the second order imposes a challenge to the discussion of the secondary gravitational waves gene…
Primordial black holes and secondary gravitational waves from k/G inflation
Jiong Lin, Qing Gao, Yungui Gong +3
The possibility that in the mass range around most of dark matter constitutes of primordial black holes (PBHs) is a very interesting topic. To produce PBHs with…
