Datsets:

This Zenodo deposit includes datasets related to the article, ‘Beyond the Brightest: A Deep Learning Approach to Identifying Major and Minor Galaxy Mergers in CANDELS at z ∼ 1‘ (preprint: arXiv.2510.12173 ; ApJ article: 10.3847/1538-4357/ae7a43

Dataset directories include train, validation, and test subdirectories, which include both classes within subdirectories. Code to produce these datasets is found on Github. All datasets were split into an 70%/15%/15%train/validation/test split.

Merger Tables:

The catalog of galaxies from TNG50 that we use to create our images, along with merger stage, star formation rate, and stellar mass information.

z1mocks:

The mock image dataset in physical units (erg/cm^2/s/$A$ ).

z1mocks_norm:

The mock image dataset normalized with asinh stretch, ready to input to the CNN.

z1mocks_1filtgrey:

The mock image dataset normalized with asinh stretch, in only the F160W filter, ready to input to the CNN.

z1mocks_3filtgrey:

The mock image dataset normalized with asinh stretch, with all three filters summed into one input channel, ready to input to the CNN.

nano_1_trial1_lr3.154957151204336e-07_epoch120.pth:

The saved weights from our model at the epoch used for the test set. These weights were used to produce all plots in the paper.
