<p>I'm curious if there is a standard dataset for redshift-mass or redshift-metallicity like there is for redshift-distance with Pantheon+SH0ES.</p>

<p>There is NED, which has millions of redshifts, but mass and metallicity aren't part of its results.</p>

<p>It'd be nice to have 10's of thousands (if not more) data points available with one or both of those properties. Does such a project exist?</p>

Mass continues to grow with radius for galaxies and  depends on assumed distance. Metallicity varies with radius and method used to deduce it.  Catalogs tend to stick to unambiguous observable, like flux within a certain subtended angular radius.   The best is probably Hyperleda.

For redshift-mass I found this:

(2019) Zou et al  
**Photometric Redshifts and Stellar Masses for Galaxies from the DESI Legacy Imaging Surveys**  
<https://ui.adsabs.harvard.edu/abs/2019ApJS..242....8Z/abstract>

Data file can be found here:

<https://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/242/8#/browse>

300M galaxies, from 0 < z < 1.3

For redshift-metallicity:

(2023) Zou et al  
**A Large Sample of Extremely Metal-poor Galaxies at z<1 Identified from the DESI Early Data**  
<https://arxiv.org/abs/2312.00300>

Data files:

<https://zenodo.org/records/10276189>

These are detected oxygen emission lines, so a much smaller dataset.
