An investigation of the star-forming main sequence considering the nebular continuum emission at low-z
Henrique Miranda, Ciro Pappalardo, Polychronis Papaderos +7
The code FADO is the first publicly available population spectral synthesis tool that treats the contribution from ionised gas to the observed emission self-consistently. We study…
Structural analysis of massive galaxies using HST deep imaging at z < 0.5
Sandra N. dos Reis, Fernando Buitrago, Polychronis Papaderos +11
Taking advantage of HST CANDELS data, we analyze the lowest redshift (z<0.5) massive galaxies in order to disentangle their structural constituents and study possible faint non-axi…
Identifying the first generation of radio powerful AGN in the Universe with the SKA
Jose Afonso, Jordi Casanellas, Isabella Prandoni +4
One of the most challenging and exciting subjects in modern astrophysics is that of galaxy formation at the epoch of reionisation. The SKA, with its revolutionary capabilities in t…
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…
