Constraints on star-forming galaxies at z≥ 6.5 from HAWK-I Y-band imaging of GOODS-South
Hickey, S.; Bunker, A.; Jarvis, M.J.; Chiu, K.; Bonfield, D. (2010)We present the results of our search for high-redshift Lyman-break galaxies over the GOODS-South field. We use Hubble Space Telescope (HST)-ACS data in B, V, i' & z', Very Large Telescope (VLT)-ISAAC J and Ks, Spitzer–Infrared ... -
The contribution of high-redshift galaxies to cosmic reionization : new results from deep WFC3 imaging of the Hubble Ultra Deep Field
Bunker, A.; Wilkins, S.; Ellis, R.S.; Stark, D.; Lorenzoni, S.; Chiu, K.; Lacy, M.; Jarvis, M.J.; Hickey, S. (2010)We have searched for star-forming galaxies at z≈ 7–10 by applying the Lyman-break technique to newly released Y-, J- and H-band images (1.1, 1.25 and 1.6 μm) from Wide Field Camera 3 (WFC3) on the Hubble Space Telescope. ... -
GRB 080503: Implications of a Naked Short Gamma-Ray Burst Dominated by Extended Emission
Perley, D.A.; Metzger, B.D.; Granot, J.; Butler, N.R.; Sakamoto, T.; Ramirez-Ruiz, E.; Levan, A.; Bloom, J.S.; Miller, A.A.; Bunker, A.; Chen, H-W.; Filippenko, A.; Gehrels, N.; Glazebrook, K.; Hall, P.B.; Hurley, K.; Kocevski, D.; Li, W.; Lopez, S.; Norris, J.; Piro, A.L.; Poznanski, D.; Prochaska, J.X.; Quataert, E.; Tanvir, N. (2009)We report on observations of GRB 080503, a short gamma-ray burst (GRB) with very bright extended emission (about 30 times the gamma-ray fluence of the initial spike) in conjunction with a thorough comparison to other short ... -
Identification and properties of intense star-forming galaxies at redshifts z > 10
Robertson, B. E.; Tacchella, S.; Johnson, B. D.; Hainline, K.; Whitler, L.; Eisenstein, D. J.; Endsley, R.; Rieke, M.; Stark, D. P.; Alberts, S.; Dressler, A.; Egami, E.; Hausen, R.; Rieke, G.; Shivaei, I.; Williams, C. C.; Willmer, C. N. A.; Arribas, S.; Bonaventura, N.; Bunker, A.; Cameron, A. J.; Carniani, S.; Charlot, S.; Chevallard, J.; Curti, M.; Curtis-Lake, E.; D'Eugenio, F.; Jakobsen, P.; Looser, T. J.; Lützgendorf, N.; Maiolino, R.; Maseda, M. V.; Rawle, T.; Rix, H. -W.; Smit, R.; Übler, H.; Willott, C.; Witstok, J.; Baum, S.; Bhatawdekar, R.; Boyett, K.; Chen, Z.; Graaff, A. de; Florian, M.; Helton, J. M.; Hviding, R. E.; Ji, Z.; Kumari, N.; Lyu, J.; Nelson, E.; Sandles, L.; Saxena, A.; Suess, K. A.; Sun, F.; Topping, M.; Wallace, I. E. B. (2023-04-04)Surveys with the James Webb Space Telescope (JWST) have discovered candidate galaxies in the first 400 Myr of cosmic time. Preliminary indications have suggested these candidate galaxies may be more massive and abundant ... -
A Population of Faint Extended Line Emitters and the Host Galaxies of Optically Thick QSO Absorption Systems
Rauch, M.; Haehnelt, M.; Bunker, A.; Becker, G.; Marleau, F.; Graham, J.; Cristiani, S.; Jarvis, M.J.; Lacey, C.; Morris, S.L.; Peroux, C.; Roettgering, H.; Theuns, T. (2008) -
Probing ∼L* Lyman-break galaxies at z≈ 7 in GOODS-South with WFC3 on Hubble Space Telescope
Wilkins, S.; Bunker, A.; Ellis, R.S.; Stark, D.; Stanway, E.R.; Chiu, K.; Lorenzoni, S.; Jarvis, M.J. (2010)We analyse recently acquired near-infrared Hubble Space Telescope imaging of the Great Observatories Origins Deep Survey (GOODS)-South field to search for star-forming galaxies at z≈ 7.0 . By comparing Wide Field Camera 3 ... -

Lawrence, J.S.; Ashley, M.C.B.; Bailey, J.; Navascues, D.B.Y.; Bedding, T.R.; Bland-Hawthorn, J.; Bond, I.; Boulanger, F.; Bouwens, R.; Bruntt, H.; Bunker, A.; Burgarella, D.; Burton, M.G.; Busso, M.; Coward, D.; Cioni, M-R.L. (2009)PILOT (the Pathfinder for an International Large Optical Telescope) is a proposed 2.5-m optical/infrared telescope to be located at Dome C on the Antarctic plateau. Conditions at Dome C are known to be exceptional for ...
