A New Method for measuring Weak Gravitational Lensing Shear using Higher Order Spin-2 HOLICs
Yuki Okura, Toshifumi Futamase
We investigate the possibility to use higher order moments of gravitational lensed images in the weak lensing analysis. For this purpose we employ spin-2 component of HOLICs(Higher…
A Method for Weak Lensing Flexion Analysis by the HOLICs Moment Approach
Yuki Okura, Keiichi Umetsu, Toshifumi Futamase
We have developed a method for measuring higher-order weak lensing distortions of faint background galaxies, namely the weak gravitational flexion, by fully extending the Kaiser, S…
A New Measure for Weak Lensing Flexion
Yuki Okura, Keiichi Umetsu, Toshifumi Futamase
We study a possibility to use the octopole moment of gravitationally lensed images as a direct measure of the third-order weak gravitational lensing effect, or the gravitational fl…
