Gauge dependence of scalar-induced gravitational waves from isocurvature perturbations: Analytical results
Arshad Ali, Yang Lei, Mudassar Sabir
We analytically study the gauge dependence of scalar-induced gravitational waves (SIGWs) sourced by primordial isocurvature perturbations during radiation domination (RD), working…

On the gauge dependence of scalar induced secondary gravitational waves during radiation and matter domination eras
Arshad Ali, Ya-Peng Hu, Mudassar Sabir +1
We revisit the vital issue of gauge dependence in the scalar-induced secondary gravitational waves (SIGWs), focusing on the radiation domination (RD) and matter domination (MD) era…

Inflation with Gauss-Bonnet coupling
Zhu Yi, Yungui Gong, Mudassar Sabir
We consider inflationary models with the inflaton coupled to the Gauss-Bonnet term assuming a special relation between the two slow-roll parameters and . For…
