Spectroscopy of z ~ 7 candidate galaxies: Using Lyman-alpha to constrain the neutral fraction of hydrogen in the high-redshift universe
Joseph Caruana, Andrew J. Bunker, Stephen M. Wilkins +4
Following our previous spectroscopic observations of galaxies with Gemini/GNIRS and VLT/XSHOOTER, which targeted a total of 8 objects, we present here our results from a deep…
Constraining the Bright-end of the UV Luminosity Function for z ~ 7 - 9 Galaxies: results from CANDELS/GOODS-South
Silvio Lorenzoni, Andrew J. Bunker, Stephen M. Wilkins +3
The recent Hubble Space Telescope near-infrared imaging with the Wide-Field Camera #3 (WFC3) of the GOODS-South field in the CANDELS program covering nearly 100arcmin^2, along with…
No Evidence for Lyman-alpha Emission in Spectroscopy of z > 7 Candidate Galaxies
Joseph Caruana, Andrew J. Bunker, Stephen M. Wilkins +5
We present Gemini/GNIRS spectroscopic observations of 4 z-band (z~7) dropout galaxies and VLT/XSHOOTER observations of one z-band dropout and 3 Y-band (z~8-9) dropout galaxies in t…
The UV Properties of Star Forming Galaxies I: HST WFC3 Observations of Very-high Redshift Galaxies
Stephen M. Wilkins, Andrew J. Bunker, Elizabeth Stanway +2
The acquisition of deep Near-IR imaging with Wide Field Camera 3 on the Hubble Space Telescope has provided the opportunity to study the very-high redshift Universe. For galaxies u…
Candidate z~8-9 Galaxies from WFC3 Imaging
Silvio Lorenzoni, Andrew Bunker, Stephen Wilkins +3
We present a search for galaxies at 7.6<z<9.8 using the latest HST WFC3 near-infrared data, based on the Lyman-break technique. We search for galaxies which have large (Y-J) colour…
New Star Forming Galaxies at z\approx 7 from WFC3 Imaging
Stephen M. Wilkins, Andrew J. Bunker, Silvio Lorenzoni +1
The addition of Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) has led to a dramatic increase in our ability to study the z>6 Universe. The increase in the near-inf…
A wide-field HI mosaic of Messier 31. II.The disk warp, rotation and the dark matter halo
Edvige Corbelli, Silvio Lorenzoni, René A. M. Walterbos +2
We test cosmological models of structure formation using the rotation curve of the nearest spiral galaxy, M31, determined using a recent deep, full-disk 21-cm imaging survey smooth…
Probing Lyman-break Galaxies at in GOODS-South with WFC3 on HST
Stephen M. Wilkins, Andrew J. Bunker, Richard S. Ellis +5
We analyse recently acquired near-infrared Hubble Space Telescope imaging of the GOODS-South field to search for star forming galaxies at z~7.0. By comparing WFC 3 0.98 micron Y-ba…
The Contribution of High Redshift Galaxies to Cosmic Reionization: New Results from Deep WFC3 Imaging of the Hubble Ultra Deep Field
Andrew Bunker, Stephen Wilkins, Richard Ellis +6
We have searched for star-forming galaxies at z~7 by applying the Lyman-break technique to newly-released 1.1micron Y-band images from WFC3 on HST. By comparing these images of the…
