Systematic uncertainties on DESI Tully-Fisher distances constrained with Integral Field Spectroscopy
Utsav Siwakoti, Lluis Galbany, Kelly A. Douglass +40
The Tully--Fisher (TF) relation is an empirical tool for estimating distances to spiral galaxies. The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity (PV) Survey uses…
The Extended Baryonic Tully-Fisher Relation for SDSS MaNGA Galaxies
Nitya Ravi, Kelly A. Douglass, Regina Demina
The baryonic Tully-Fisher relation (BTFR), a relationship between rotational velocity and baryonic mass in spiral galaxies, probes the relative content of baryonic and dark matter…
Quantifying the Active Galactic Nuclei Fraction in Cosmic Voids via Mid-Infrared Variability
Anish S. Aradhey, Anca Constantin, Michael S. Vogeley +1
Observations and theoretical simulations suggest that the large scale environment plays a significant role in how galaxies form and evolve and, in particular, whether and when gala…
The impact of void-finding algorithms on galaxy classification
Fatima Zaidouni, Dahlia Veyrat, Kelly A. Douglass +1
We explore how the definition of a void influences the conclusions drawn about the impact of the void environment on galactic properties using two void-finding algorithms in the Vo…
A Full Accounting of the Visible Mass in SDSS MaNGA Disk Galaxies
Nitya Ravi, Kelly A. Douglass, Regina Demina
We present a study of the ratio of visible mass to total mass in spiral galaxies to better understand the relative amount of dark matter present in galaxies of different masses and…
Updated void catalogs of the SDSS DR7 main sample
Kelly A. Douglass, Dahlia Veyrat, Segev BenZvi
We produce several public void catalogs using a volume-limited subsample of the Sloan Digital Sky Survey Data Release 7 (SDSS DR7). Using new implementations of three different voi…
Dependence of the ratio of total to visible mass on observable properties of SDSS MaNGA galaxies
Kelly A. Douglass, Regina Demina
Using spectroscopic observations from the SDSS MaNGA DR15, we study the relationships between the ratio of total to visible mass and various parameters characterizing the evolution…
The influence of the void environment on the ratio of dark matter halo mass to stellar mass in SDSS MaNGA galaxies
Kelly A. Douglass, Jacob A. Smith, Regina Demina
We study how the void environment affects the formation and evolution of galaxies in the universe by comparing the ratio of dark matter halo mass to stellar mass of galaxies in voi…
Influence of the Void Environment on Chemical Abundances in Dwarf Galaxies and Implications for Connecting Star Formation and Halo Mass
Kelly A. Douglass, Michael S. Vogeley, Renyue Cen
We study how the void environment affects galactic chemical evolution by comparing the oxygen and nitrogen abundances of dwarf galaxies in voids with dwarf galaxies in denser regio…
Large-scale environmental dependence of the abundance ratio of nitrogen to oxygen in blue, star-forming galaxies fainter than L*
Kelly A. Douglass, Michael S. Vogeley
We examine how the cosmic environment affects the chemical evolution of galaxies in the Universe by comparing the N/O ratio of dwarf galaxies in voids with dwarf galaxies in more d…
Determining the large-scale environmental dependence of gas-phase metallicity in dwarf galaxies
Kelly A. Douglass, Michael S. Vogeley
We study how the cosmic environment affects galaxy evolution in the Universe by comparing the metallicities of dwarf galaxies in voids with dwarf galaxies in more dense regions. Ra…
