TEMPLATES: Characterization of a Merger in the Dusty Lensing SPT0418-47 System
Jared Cathey, Anthony H. Gonzalez, Sidney Lower +22
We present JWST and ALMA results for the lensing system SPT0418-47, which includes a strongly-lensed, dusty star-forming galaxy at redshift z=4.225 and an associated multiply-image…
Outshining by Recent Star Formation Prevents the Accurate Measurement of High-z Galaxy Stellar Masses
Desika Narayanan, Sidney Lower, Paul Torrey +10
In this paper, we demonstrate that the inference of galaxy stellar masses via spectral energy distribution (SED) fitting techniques for galaxies formed in the first billion years a…
Cosmic Sands II: Challenges in Predicting and Measuring High-z Dust Temperatures
Sidney Lower, Desika Narayanan, Chia-Yu Hu +1
In the current era of high-z galaxy discovery with JWST and ALMA, our ability to study the stellar populations and ISM conditions in a diverse range of galaxies at Cosmic Dawn has…
Cosmic Sands: The Origin of Dusty, Star-forming Galaxies in the Epoch of Reionization
Sidney Lower, Desika Narayanan, Qi Li +1
We present the Cosmic Sands suite of cosmological zoom-in simulations based on the Simba galaxy formation model in order to study the build up of the first massive and dusty galaxi…
Star Formation Suppresion by Tidal Removal of Cold Molecular Gas from an Intermediate-Redshift Massive Post-Starburst Galaxy
Justin S. Spilker, Katherine A. Suess, David J. Setton +7
Observations and simulations have demonstrated that star formation in galaxies must be actively suppressed to prevent the formation of over-massive galaxies. Galactic outflows driv…
Recovering the star formation histories of recently-quenched galaxies: the impact of model and prior choices
Katherine A. Suess, Joel Leja, Benjamin D. Johnson +7
Accurate models of the star formation histories (SFHs) of recently-quenched galaxies can provide constraints on when and how galaxies shut down their star formation. The recent dev…
How Well Can We Measure Galaxy Dust Attenuation Curves? The Impact of the Assumed Star-Dust Geometry Model in SED Fitting
Sidney Lower, Desika Narayanan, Joel Leja +3
One of the most common methods for inferring galaxy attenuation curves is via spectral energy distribution (SED) modeling, where the dust attenuation properties are modeled simulta…
SQuIGGLE: Studying Quenching in Intermediate-z Galaxies -- Gas, AnguLar Momentum, and Evolution
Katherine A. Suess, Mariska Kriek, Rachel Bezanson +12
We describe the SQuIGGLE survey of intermediate-redshift post-starburst galaxies. We leverage the large sky coverage of the SDSS to select ~1300 recently-quenched galaxies at 0.5<z…
Quenching and the UVJ diagram in the SIMBA cosmological simulation
Hollis B. Akins, Desika Narayanan, Katherine E. Whitaker +5
Over the past decade, rest-frame color-color diagrams have become popular tools for selecting quiescent galaxies at high redshift, breaking the color degeneracy between quiescent a…
{\sc mirkwood:} Fast and Accurate SED Modeling Using Machine Learning
Sankalp Gilda, Sidney Lower, Desika Narayanan
Traditional spectral energy distribution (SED) fitting codes used to derive galaxy physical properties are often uncertain at the factor of a few level owing to uncertainties in ga…
Powderday: Dust Radiative Transfer for Galaxy Simulations
Desika Narayanan, Matthew J. Turk, Thomas Robitaille +18
We present Powderday, a flexible, fast, open-source dust radiative transfer package designed to interface with galaxy formation simulations. Powderday builds on FSPS population syn…
How Well Can We Measure the Stellar Mass of a Galaxy: The Impact of the Assumed Star Formation History Model in SED Fitting
Sidney Lower, Desika Narayanan, Joel Leja +3
The primary method for inferring the stellar mass () of a galaxy is through spectral energy distribution (SED) modeling. However, the technique rests on assumptions such as th…
Galaxy growth in a massive halo in the first billion years of cosmic history
D. P. Marrone, J. S. Spilker, C. C. Hayward +34
According to the current understanding of cosmic structure formation, the precursors of the most massive structures in the Universe began to form shortly after the Big Bang, in reg…
