Precise weak lensing constraints from deep high-resolution images: VLT/HAWK-I analysis of the super-massive galaxy cluster RCS2232727.7020437 at
Tim Schrabback, Mischa Schirmer, Remco F. J. van der Burg +16
We demonstrate that deep good-seeing VLT/HAWK-I images complemented with +-band photometry can yield a sensitivity for weak lensing studies of massive galaxy c…
The Magellan Evolution of Galaxies Spectroscopic and Ultraviolet Reference Atlas (MEGaSaURA) I: The Sample and the Spectra
J. R. Rigby, M. B. Bayliss, K. Sharon +7
We introduce Project MEGaSaURA: The Magellan Evolution of Galaxies Spectroscopic and Ultraviolet Reference Atlas. MEGaSaURA comprises medium-resolution, rest-frame ultraviolet spec…
The Magellan Evolution of Galaxies Spectroscopic and Ultraviolet Reference Atlas (MEGaSaURA) II: Stacked Spectra
J. R. Rigby, M. B. Bayliss, J. Chisholm +8
We stack the rest-frame ultraviolet spectra of N=14 highly magnified gravitationally lensed galaxies at redshifts 1.6<z<3.6. The resulting new composite spans $900< λ_{rest} < 3000…
Spatially Resolved Patchy Lyman- Emission Within the Central Kiloparsec of a Strongly Lensed Quasar Host Galaxy at z = 2.8
Matthew B. Bayliss, Keren Sharon, Ayan Acharyya +10
We report the detection of extended Lyman- emission from the host galaxy of SDSS~J2222+2745, a strongly lensed quasar at . Spectroscopic follow-up clearly reveals exten…
Star Formation at z=2.481 in the Lensed Galaxy SDSS J1110+6459, I: Lens Modeling and Source Reconstruction
Traci L. Johnson, Keren Sharon, Michael D. Gladders +6
Using the combined resolving power of the Hubble Space Telescope and gravitational lensing, we resolve star-forming structures in a z~2.5 galaxy on scales much smaller than the usu…
Star Formation at z=2.481 in the Lensed Galaxy SDSS J1110+6459: Star Formation down to 30 parsec scales
Traci L. Johnson, Jane R. Rigby, Keren Sharon +7
We present measurements of the surface density of star formation, the star-forming clump luminosity function, and the clump size distribution function, for the lensed galaxy SGAS J…
Star Formation at z=2.481 in the Lensed Galaxy SDSS J1110+6459, II: What is missed at the normal resolution of the Hubble Space Telescope?
J. R. Rigby, T. L. Johnson, K. Sharon +6
For lensed galaxy SGAS J111020.0+645950.8 at redshift z=2.481, which is magnified by a factor of 28 +- 8, we analyze the morphology of star formation as traced by rest-frame ultrav…
The Remarkable Similarity of Massive Galaxy Clusters From z~0 to z~1.9
M. McDonald, S. W. Allen, M. Bayliss +12
We present the results of a Chandra X-ray survey of the 8 most massive galaxy clusters at z>1.2 in the South Pole Telescope 2500 deg^2 survey. We combine this sample with previousl…
