Anisotropic separate universe : Long-wavelength perturbations and conserved quantities
Daiki Saito, Atsushi Naruko
We investigate the long-wavelength evolution of linear perturbations in a homogeneous and anisotropic background with a scalar field coupled to a vector field. Using the spatial gr…

Primordial black holes in excursion set theory: Formation probabilities, mass functions, and window functions
Hayami Iizuka, Daiki Saito, Koki Tokeshi
We study the mass function of primordial black holes (PBHs) within the excursion-set theory, in which the response of the stochastic density contrast to the variation of the coarse…
