Hot Gas, Cold Gas and Sub-Halos in a Lyman-alpha Blob at Redshift 2.38
Paul. J. Francis, Michael A. Dopita, James W. Colbert +5
We present integral field spectroscopy of a Lyman-alpha blob at redshift 2.38, with a spectral resolution three times better than previous published work. As with previous observat…
Lyα Emission from High Redshift Sources in COSMOS
Ryan P. Mallery, Bahram Mobasher, Peter Capak +9
We investigate spectroscopically measured Lyα equivalent widths and escape fractions of 244 sources of which 95 are Lyman Break Galaxies (LBGs) and 106 Lyman Alpha Emitters (LAEs)…
Dust extinction from Balmer decrements of star-forming galaxies at 0.75<z<1.5 with HST/WFC3 spectroscopy from the WISP survey
A. Domínguez, B. Siana, A. L. Henry +14
Spectroscopic observations of Halpha and Hbeta emission lines of 128 star-forming galaxies in the redshift range 0.75<z<1.5 are presented. These data were taken with slitless spect…
Discovery of Three Distant, Cold Brown Dwarfs in the WFC3 Infrared Spectroscopic Parallels Survey
Daniel Masters, Patrick McCarthy, Adam J. Burgasser +12
We present the discovery of three late type (>T4) brown dwarfs, including a probable Y dwarf, in the WFC3 Infrared Spectroscopic Parallels (WISP) Survey. We use the G141 grism spec…
A Type Ia Supernova at Redshift 1.55 in Hubble Space Telescope Infrared Observations from CANDELS
Steven A. Rodney, Adam G. Riess, Tomas Dahlen +23
We report the discovery of a Type Ia supernova (SNIa) at redshift z=1.55 with the infrared detector of the Wide Field Camera 3 (WFC3-IR) on the Hubble Space Telescope (HST). This o…
