Then we use the CNN to predict the total masses of galaxies (i. e., test the CNN) for the totally unknown dataset that is not used in training the CNN.

A new way to constrain the densities of intra-group medium in groups of galaxies with convolutional neural networks

1 code implementation • 8 Aug 2020 • Austin X. Shen, Kenji Bekki

One of the key parameters for the strength of RP is the density of intra-group medium ($\rho_{\rm igm}$), which is difficult to estimate if the X-ray emission from it is too weak to be observed.
