Spherical collapse and cluster number counts in DHOST theories that pass the constraints from gravitational waves
Sakdithut Jitpienka, Khamphee Karwan, David F. Mota
We investigate the spherical collapse model and the abundance of galaxy clusters in a class of degenerate higher-order scalar--tensor (DHOST) theories in which gravitational waves…

Squeezed bispectrum from multi-field inflation with curved field space metric
Sakdithut Jitpienka, Khamphee Karwan
We investigate influences of the curved field-space metric of multi-field inflationary models on the squeezed bispectrum. The reduced bispectrum in squeezed limit is computed using…
