Photometric Constraints on the Redshift of z~10 candidate UDFj-39546284 from deeper WFC3/IR+ACS+IRAC observations over the HUDF

R. J. Bouwens, P. A. Oesch, G. D. Illingworth +10

Ultra-deep WFC3/IR observations on the HUDF from the HUDF09 program revealed just one plausible z~10 candidate UDFj-39546284. UDFj-39546284 had all the properties expected of a gal…

A Strongly-Lensed Massive Ultra-Compact Quiescent Galaxy at z ~ 2.4 in the COSMOS/UltraVISTA Field

Adam Muzzin, Ivo Labbe, Marijn Franx +14

We report the discovery of a massive ultra-compact quiescent galaxy that has been strongly-lensed into multiple images by a foreground galaxy at z = 0.960. This system was serendip…

Large-Scale Star Formation-Driven Outflows at 1<z<2 in the 3D-HST Survey

Britt F. Lundgren, Gabriel Brammer, Pieter van Dokkum +18

We present evidence of large-scale outflows from three low-mass (log(M/M_sun)~9.75) star-forming (SFR >4 M_sun/yr) galaxies observed at z=1.24, z=1.35 and z=1.75 in the 3D-HST Surv…

3D-HST Grism Spectroscopy of a Gravitationally Lensed, Low-metallicity Starburst Galaxy at z=1.847

Gabriel B. Brammer, Ruben Sanchez-Janssen, Ivo Labbe +17

We present Hubble Space Telescope (HST) imaging and spectroscopy of the gravitational lens SL2SJ02176-0513, a cusp arc at z=1.847. The UV continuum of the lensed galaxy is very blu…

Halpha Equivalent Widths from the 3D-HST survey: evolution with redshift and dependence on stellar mass

Mattia Fumagalli, Shannon G. Patel, Marijn Franx +12

We investigate the evolution of the Halpha equivalent width, EW(Halpha), with redshift and its dependence on stellar mass, taking advantage of the first data from the 3D-HST survey…

The Star-formation Mass Sequence out to z=2.5

Katherine E. Whitaker, Pieter G. van Dokkum, Gabriel Brammer +1

We study the star formation rate (SFR) - stellar mass (M*) relation in a self-consistent manner from 0 < z < 2.5 with a sample of galaxies selected from the NEWFIRM Medium-Band Sur…

3D-HST: A wide-field grism spectroscopic survey with the Hubble Space Telescope

Gabriel Brammer, Pieter van Dokkum, Marijn Franx +27

We present 3D-HST, a near-infrared spectroscopic Treasury program with the Hubble Space Telescope for studying the processes that shape galaxies in the distant Universe. 3D-HST pro…

Spatially resolved Halpha maps and sizes of 57 strongly star-forming galaxies at z~1 from 3D-HST: evidence for rapid inside-out assembly of disk galaxies

Erica June Nelson, Pieter G. van Dokkum, Gabriel Brammer +13

We investigate the build-up of galaxies at z~1 using maps of Halpha and stellar continuum emission for a sample of 57 galaxies with rest-frame Halpha equivalent widths >100 Angstro…

The Evolution of the Rest-frame V-band Luminosity Function from z=4: A Constant Faint-end Slope over the Last 12 Gyr of Cosmic History

Danilo Marchesini, Mauro Stefanon, Gabriel B. Brammer +1

We present the rest-frame V-band luminosity function (LF) of galaxies at 0.4<z<4.0, measured from a near-infrared selected sample constructed from the NMBS, the FIRES, the FIREWORK…
