Description

I’m developing a method to measure galaxy shapes, which are used for weak lensing shear cosmology, using deep learning techniques. I use a convolutional neural network (CNN) to measure galaxy ellipticities from input images of simulated galaxies. The method includes PSF correction and calibration of the weak lensing shear using a method called Metacalibration.
