Perturbative Approach to the Gravitational Lensing by a Non-spherically Distorted Compact Object
Amano Saijo, Masumi Kasai
We investigate the gravitational lens effect caused by a non-spherically distorted compact object. The non-spherical property of the gravitational potential is modeled by a quadrup…

An analytical approximation of the growth function in Friedmann-Lemaître universes
Masumi Kasai
We present an analytical approximation formula for the growth function in a spatially flat cosmology with dust and a cosmological constant. Our approximate formula is written simpl…
