Observed 2MRS galaxies and reconstructed fields in a slice through the Supergalactic (left) and Galactic (right) planes. Top row. redshift-space positions of the observed 2MRS galaxies within a distance of 5 h−1 Mpc to the respective planes. The red cross marks the position of the observer (Local Group) at the origin. Middle row: neural network-reconstructed density (heat map and contours) and peculiar velocity (arrows) fields. The values represented by the contours are marked in the color bar. A reference arrow representing a velocity of 500 km s−1 is shown on the right. Some dominant structures associated with known clusters are labeled by bold black letters: Shapley, Coma, Hydra-Centaurus, Virgo, Norma, Perseus-Pisces, Ophiuchus, Triangulum Australis. Bottom row: NN-reconstructed velocity potential field (heat map and contours) overlaid with the same peculiar velocity field shown in the middle row.
