Empirically-Driven Multiwavelength K-corrections At Low Redshift
Catherine E. Fielder, Brett H. Andrews, Jeffrey A. Newman +1
K-corrections, conversions between flux in observed bands to flux in rest-frame bands, are critical for comparing galaxies at various redshifts. These corrections often rely on fit…
Are Milky-Way-like galaxies like the Milky Way? A view from SDSS-IV/MaNGA
Shuang Zhou, Alfonso Aragón-Salamanca, Michael Merrifield +3
In this paper, we place the Milky Way (MW) in the context of similar-looking galaxies in terms of their star-formation and chemical evolution histories. We select a sample of 138 M…
DESI Survey Validation Spectra Reveal an Increasing Fraction of Recently Quenched Galaxies at
David J. Setton, Biprateep Dey, Gourav Khullar +24
We utilize bright Luminous Red Galaxies (LRGs) from the novel Dark Energy Spectroscopic Instrument Survey Validation spectroscopic sample, leveraging its deep ($\sim2.5…
Optimized Photometric Redshifts for the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS)
Dritan Kodra, Brett H. Andrews, Jeffrey A. Newman +27
We present the first comprehensive release of photometric redshifts (photo-z's) from the Cosmic Assembly Near-Infrared Deep Extragalactic Legacy Survey (CANDELS) team. We use stati…
How well do local relations predict gas-phase metallicity gradients? Results from SDSS-IV MaNGA
Nicholas F. Boardman, Gail Zasowski, Jeffrey A. Newman +8
Gas-phase metallicity gradients in galaxies provide important clues to those galaxies' formation histories. Using SDSS-IV MaNGA data, we previously demonstrated that gas metallicit…
SDSS-IV MaNGA: How the stellar populations of passive central galaxies depend on stellar and halo mass
Grecco A. Oyarzun, Kevin Bundy, Kyle B. Westfall +23
We analyze spatially resolved and co-added SDSS-IV MaNGA spectra with signal-to-noise ~100 from 2200 passive central galaxies (z~0.05) to understand how central galaxy assembly dep…
