VizieR Online Data Catalog: Decomposition of Galactic sky with autoencoders (Milosevic+ 2021)
Abstract
The images show compressed Galactic all-sky maps as calculated by a neural network architecture called autoencoder. The autoencoder is trained to calculate a compressed representation of 39 Galactic all-sky maps compiled by Mueller et al. (2018A&A...620A..64M), covering frequencies from the radio to the gamma-ray regime. The results show the posterior mean and variance maps of the compression, which encode (1) the dense interstellar medium (ISM), (2) the hot and dilute regions of the ISM, and (3) the CMB. The images are in HEALPix format (Gorski et al., 2005ApJ...622..759G) with NSIDE=128.
