Journal ArticleDOI
Galaxy Merger Rates up to z ˜ 3 Using a Bayesian Deep Learning Model: A Major-merger Classifier Using IllustrisTNG Simulation Data
Leonardo Ferreira,Christopher J. Conselice,Kenneth Duncan,Kenneth Duncan,Ting-Yun Cheng,Alex Griffiths,Amy Whitney +6 more
TL;DR: In this paper, the authors used deep learning convolutional neural networks (CNNs) trained with simulated galaxies from the IllustrisTNG cosmological simulation to classify major mergers and measure galaxy merger rates.

TL;DR: The Origins Space Telescope as mentioned in this paper was designed to trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life, and it was the first telescope to operate at mid-and far-infrared (IR) wavelengths.
