Do spatial distributions of dust grains in galaxies have typical forms, as do spatial distributions of stars? We investigate whether or not the distributions resemble uniform foreground screens, as commonly assumed by the high-redshift galaxy community. We use rest-frame infrared, ultraviolet, and H$\alpha$ line luminosities of dust-poor and dusty galaxies at z ~ 0 and z ~ 1 to compare measured H$\alpha$ escape fractions with those predicted by the Calzetti attenuation formula. The predictions…

The Flattening of Dust Attenuation Curve to z=2.5

We examine the evolution of dust attenuation curve using a sample of 9504 disk star-forming galaxies (SFGs) selected from the CANDELS and 3D-HST surveys and a new technique relying on the fact that


We derive the mean wavelength dependence of stellar attenuation in a sample of 239 high redshift ( 1.90 < z < 2.35 ?> ) galaxies selected via Hubble Space Telescope WFC3 IR grism observations of

Dust Attenuation, Bulge Formation, and Inside-out Quenching of Star Formation in Star-forming Main Sequence Galaxies at z ∼ 2

We derive 2D dust attenuation maps at ∼1 kpc resolution from the UV continuum for 10 galaxies on the z ∼ 2 star-forming main sequence (SFMS). Comparison with IR data shows that 9 out of 10 galaxies

UV to IR Luminosities and Dust Attenuation Determined from ~4000 K-Selected Galaxies at 1

We build a set of composite galaxy spectral energy distributions (SEDs) by de-redshifting and scaling multi-wavelength photometry from galaxies in the ZFOURGE survey, covering the CDFS, COSMOS, and



The MOSDEF Survey: Measurements of Balmer Decrements and the Dust Attenuation Curve at Redshifts z~1.4-2.6

We present results on the dust attenuation curve of z ∼ 2 galaxies using early observations from the MOSFIRE Deep Evolution Field survey. Our sample consists of 224 star-forming galaxies with zspec =

Stellar Masses from the CANDELS Survey: The GOODS-South and UDS Fields

We present the public release of the stellar mass catalogs for the GOODS-S and UDS fields obtained using some of the deepest near-IR images available, achieved as part of the Cosmic Assembly

Cosmic Star-Formation History

Over the past two decades, an avalanche of new data from multiwavelength imaging and spectroscopic surveys has revolutionized our view of galaxy formation and evolution. Here we review the range of
