Highly Efficient Selection of High-Redshift Emission-Line Galaxies for future DESI-like surveys with Deep Multi-band Imaging
Yoquelbin Salcedo Hernandez, Jeffrey A. Newman, Brett. H. Andrews +53
Emission-line galaxies (ELGs) are an important tracer of baryon acoustic oscillations (BAO) and large-scale structure (LSS) at . In this work, we investigate the feasibility…
Electron temperature relations and the direct N, O, Ne, S and Ar abundances of 49959 star-forming galaxies in DESI Data Release 2
D. Scholte, F. Cullen, J. Moustakas +42
We present the largest direct-method abundance catalogue of galaxies to date, containing measurements of 49959 star-forming galaxies at z < 0.96 from DESI Data Release 2. By direct…
Optimizing Photometric Redshift Training Sets I: Efficient Compression of the Galaxy Color-Redshift Relation with UMAP
Finian Ashmead, Jeffrey A. Newman, Brett H. Andrews +4
Spectroscopic datasets are essential for training and calibrating photometric redshift (photo-) methods. However, spectroscopic redshifts (spec-'s) constitute a biased and sp…
Deep Learning Improves Photometric Redshifts in All Regions of Color Space
Emma R. Moran, Brett H. Andrews, Jeffrey A. Newman +1
Photometric redshifts (photo-'s) are crucial for the cosmology, galaxy evolution, and transient science drivers of next-generation imaging facilities like the Euclid Mission, th…
DESI Massive Post-Starburst Galaxies at have compact structures and dense cores
Yunchong Zhang, David J. Setton, Sedona H. Price +33
Post-starburst galaxies (PSBs) are young quiescent galaxies that have recently experienced a rapid decrease in star formation, allowing us to probe the fast-quenching period of gal…
Emission Line Predictions for Mock Galaxy Catalogues: a New Differentiable and Empirical Mapping from DESI
Ashod Khederlarian, Jeffrey A. Newman, Brett H. Andrews +43
We present a simple, differentiable method for predicting emission line strengths from rest-frame optical continua using an empirically-determined mapping. Extensive work has been…
APOGEE DR14/DR15 Abundances in the Inner Milky Way
G. Zasowski, M. Schultheis, S. Hasselquist +14
We present an overview of the distributions of 11 elemental abundances in the Milky Way's inner regions, as traced by APOGEE stars released as part of SDSS Data Release 14/15 (DR14…
