The phylogenetic placement of novel bacterial taxa identified in this study. Phylogenetic trees (A-J) were constructed using a set of available marker sequences. The central tree of life indicates the position of novel species in the bacterial tree of life. Novel species and the outgroups are highlighted in red and blue, respectively, and their corresponding NCBI accessions are provided. biorxiv.org

1-to-1 plots of our inferred abundances vs. the reported abundances of M dwarfs from the Hyades cluster using either our FGK-M sample (top row) or the Souto et al. (2022) sample (bottom row) as the training set. The points are colored by the χ2 of the flux model spectral fit. We report the rms scatter between the inferred and reported abundance values from Wanderley et al. (2023) in the top left of each plot, and the scatter of the reported values for that label below. The rms scatter from training on our FGK-M sample (∼0.05 dex) are lower than those from training on the Souto et al. (2022) sample (∼0.07−0.08 dex). -- astro-ph.SR

Spectrally red-sloped sites on Ceres identified by the deep neural network. Steep red-sloped spectra (organic-rich) are shown in/as red boxes. Yellow boxes indicate locations of moderately red-sloped pixels, which except for Vinotonus do not display the ∼3.4 micron organic feature. Occator red-sloped material is not marked because of its different nature (see text). A blue rectangle outlines an area overlapping Urvara and Yalode, where carbonate-rich materials are exposed. The exact locations of the identified reddish material are marked by small light-green boxes. The area bounded within the blue rectangle is referred to as the “Urvara-Yalode” region. See Figure 9 and Figure S9 in Supporting Information S1 for more details on these sites. Background image is the equirectangular global mosaic of Ceres created using ∼130 m/pix High Altitude Mapping Orbit color data (R-965 nm; G-749 nm; B-438 nm). -- AGU Advances
