SN Refsdal: Classification as a Luminous and Blue SN 1987A-like Type II Supernova
P. L. Kelly, G. Brammer, J. Selsing +19
We have acquired Hubble Space Telescope (HST) and Very Large Telescope near-infrared spectra and images of supernova (SN) Refsdal after its discovery as an Einstein cross in Fall 2…
Spatially-resolved dust maps from Balmer decrements in galaxies at z~1.4
Erica June Nelson, Pieter G. van Dokkum, Ivelina G. Momcheva +6
We derive average radial gradients in the dust attenuation towards HII regions in 609 galaxies at z~1.4, using measurements of the Balmer decrement out to r~3kpc. The Balmer decrem…
The Grism Lens-Amplified Survey from Space (GLASS). V. Extent and spatial distribution of star formation in z~0.5 cluster galaxies
Benedetta Vulcani, Tommaso Treu, Kasper B. Schmidt +14
We present the first study of the spatial distribution of star formation in z~0.5 cluster galaxies. The analysis is based on data taken with the Wide Field Camera 3 as part of the…
The 3D-HST Survey: Hubble Space Telescope WFC3/G141 grism spectra, redshifts, and emission line measurements for galaxies
Ivelina G. Momcheva, Gabriel B. Brammer, Pieter G. van Dokkum +27
We present reduced data and data products from the 3D-HST survey, a 248-orbit HST Treasury program. The survey obtained WFC3 G141 grism spectroscopy in four of the five CANDELS fie…
Young Galaxy Candidates in the Hubble Frontier Fields. II. MACS,J0416-2403
Leopoldo Infante, Wei Zheng, Nicolas Laporte +14
We searched for z > 7 Lyman-break galaxies (LBGs) in the optical-to-mid-infrared Hubble Frontier Field and associated parallel field observations of the strong-lensing cluster MACS…
The Grism Lens-Amplified Survey from Space (GLASS). I. Survey overview and first data release
T. Treu, K. B. Schmidt, G. B. Brammer +19
We give an overview of the Grism Lens Amplified Survey from Space (GLASS), a large Hubble Space Telescope program aimed at obtaining grism spectroscopy of the fields of ten massive…
