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…
