Using Machine Learning to Determine Morphologies of $z < 1$ AGN Host Galaxies in the Hyper Suprime-Cam Wide Survey

Chuan Tian, C. Megan Urry, Aritra Ghosh +9

We present a machine-learning framework to accurately characterize morphologies of Active Galactic Nucleus (AGN) host galaxies within $z < 1$ . We first use PSFGAN to decouple host ga…

Morphological Parameters and Associated Uncertainties for 8 Million Galaxies in the Hyper Suprime-Cam Wide Survey

Aritra Ghosh, C. Megan Urry, Aayush Mishra +10

We use the Galaxy Morphology Posterior Estimation Network (GaMPEN) to estimate morphological parameters and associated uncertainties for $\sim 8$ million galaxies in the Hyper Supr…

GaMPEN: A Machine Learning Framework for Estimating Bayesian Posteriors of Galaxy Morphological Parameters

Aritra Ghosh, C. Megan Urry, Amrit Rau +11

We introduce a novel machine learning framework for estimating the Bayesian posteriors of morphological parameters for arbitrarily large numbers of galaxies. The Galaxy Morphology…
