Galaxy and Mass Assembly (GAMA): The Properties of Quasar Host Galaxies: Star Formation Histories and Stellar Populations
Maria B. Stone, Roberto De Propris, Clare Wethers +5
We investigated the star formation history and stellar populations of a sample of 205 Type I quasar host galaxies (0.1z0.35) and compared with normal (non-active) galaxies of…
Galaxy And Mass Assembly: A new approach to quantifying dust in galaxies
B. Farley, U. T. Ahmed, A. M. Hopkins +8
We introduce a new approach to quantifying dust in galaxies by combining information from the Balmer decrement (BD) and the dust mass (). While there is no explicit correlatio…
A comparison of dust content and properties in GAMA/G10-COSMOS/3D-HST and SIMBA cosmological simulations
Trevor Butrum, Benne Holwerda, Romeel Dave +3
The abundance of dust within galaxies directly influences their evolution. Contemporary models attempt to match this abundance by simulating the processes of dust creation, growth,…
Galaxies in the Epoch of Reionization Are All Bark and No Bite -- Plenty of Ionizing Photons, Low Escape Fractions
Casey Papovich, Justin W. Cole, Weida Hu +27
Early results from JWST suggest that epoch-of-reionization (EoR) galaxies produce copious ionizing photons, which, if they escape efficiently, could cause reionization to occur too…
The Galaxy Zoo Catalogs for the Galaxy And Mass Assembly (GAMA) Survey
Benne W. Holwerda, Clayton Robertson, Kyle Cook +16
Galaxy Zoo is an online project to classify morphological features in extra-galactic imaging surveys with public voting. In this paper, we compare the classifications made for two…
Ground- and Space-Based Dust Observations of VV 191 Overlapping Galaxy Pair
C. Robertson, B. Holwerda, J. Young +12
The Balmer decrement (H/H) provides a constraint on attenuation, the cumulative effects of dust grains in the ISM. The ratio is a reliable spectroscopic tool for deriving the…
Detection and characterization of M-L-T-Y dwarfs belonging to the Milky Way Disks and Stellar Halo with the Roman Space Telescope
Benne Holwerda, Nor Pirzkal, Adam Burgasser +1
How many low-mass stars, brown dwarfs and free-floating planets are in the Milky Way? And how are they distributed in our Galaxy? Recent studies of Milky Way interlopers in high-re…
New Lyman-alpha Emitters in EGS: Evidence of an Extended Ionized Structure at
Intae Jung, Steven L. Finkelstein, Rebecca L. Larson +21
We perform a ground-based near-infrared spectroscopic survey using the Keck/MOSFIRE spectrograph to target Ly emission at from 61 galaxies to trace the ionization st…
Galaxy And Mass Assembly: Galaxy Morphology in the Green Valley, Prominent rings and looser Spiral Arms
Dominic Smith, Lutz Haberzettl, L. E. Porter +15
Galaxies broadly fall into two categories: star-forming (blue) galaxies and quiescent (red) galaxies. In between, one finds the less populated ``green valley". Some of these galaxi…
Predicting the spectrum of UGC 2885, Rubin's Galaxy with machine learning
Benne W. Holwerda, John F. Wu, William C. Keel +10
Wu & Peek (2020) predict SDSS-quality spectra based on Pan-STARRS broad-band \textit{grizy} images using machine learning (ML). In this letter, we test their prediction for a uniqu…
Measuring Cosmic Density of Neutral Hydrogen via Stacking the DINGO-VLA Data
Qingxiang Chen, Martin Meyer, Attila Popping +13
We use the 21 cm emission line data from the DINGO-VLA project to study the atomic hydrogen gas H\,{\textsc i} of the Universe at redshifts . Results are obtained using a st…
The Sizes of Galaxies Identified in the BoRG Survey
Benne W. Holwerda, Joanna S. Bridge, Rebecca L. Steele +5
Redshift object selection is the effective limit of Hubble Space Telescope imaging capability, even when confirmed with Spitzer. If only a few photometry data points are…
