Star Formation Histories from SEDs and CMDs Agree: Evidence for Synchronized Star Formation in Local Volume Dwarf Galaxies over the Past 3 Gyr
Charlotte Olsen, Eric Gawiser, Kartheik Iyer +6
Star Formation Histories (SFHs) reveal physical processes that influence how galaxies form their stellar mass. We compare the SFHs of a sample of 36 nearby (D 4 Mpc) dwarf g…
ZFOURGE: Using Composite Spectral Energy Distributions to Characterize Galaxy Populations at 1<z<4
Ben Forrest, Kim-Vy H. Tran, Adam Broussard +12
We investigate the properties of galaxies as they shut off star formation over the 4 billion years surrounding peak cosmic star formation. To do this we categorize galax…
Discovery of Extreme [OIII]+H Emitting Galaxies Tracing an Overdensity at z~3.5 in CDF-South
Ben Forrest, Kim-Vy H. Tran, Adam Broussard +12
Using deep multi-wavelength photometry of galaxies from ZFOURGE, we group galaxies at by the shape of their spectral energy distributions (SEDs). We identify a populati…
The Lyman Continuum Escape Fraction of Star-forming Galaxies at from UVCANDELS

Improved Measurements of Galaxy Star Formation Stochasticity from the Intrinsic Scatter of Burst Indicators
Adam Broussard, Eric Gawiser, Kartheik Iyer
Measurements of short-timescale star formation variations (i.e., "burstiness") are integral to our understanding of star formation feedback mechanisms and the assembly of stellar p…
ODIN: Improved Narrowband Ly Emitter Selection Techniques for = 2.4, 3.1, and 4.5
Nicole M. Firestone, Eric Gawiser, Vandana Ramakrishnan +25
Lyman-Alpha Emitting galaxies (LAEs) are typically young, low-mass, star-forming galaxies with little extinction from interstellar dust. Their low dust attenuation allows their Ly$…
Validating Synthetic Galaxy Catalogs for Dark Energy Science in the LSST Era
Eve Kovacs, Yao-Yuan Mao, Michel Aguena +36
Large simulation efforts are required to provide synthetic galaxy catalogs for ongoing and upcoming cosmology surveys. These extragalactic catalogs are being used for many diverse…
The One-hundred-deg^2 DECam Imaging in Narrowbands (ODIN): Survey Design and Science Goals

We analyze the clustering of galaxies in the first public data release of the HSC Subaru Strategic Program. Despite the relatively small footprints of the observed fields, the data…
Star Formation Stochasticity Measured from the Distribution of Burst Indicators
Adam Broussard, Eric Gawiser, Kartheik Iyer +6
One of the key questions in understanding the formation and evolution of galaxies is how starbursts affect the assembly of stellar populations in galaxies over time. We define a bu…
