Multi-Object Near-IR H-alpha Spectroscopy of z~1 star-forming galaxies in the HDF-N
Michelle Doherty, Andrew Bunker, Robert Sharp +6
We present preliminary results from a programme to obtain multi-object near-infrared spectroscopy of galaxies at redshifts . We are using the instrument CIRPASS (the Cam…
CIRPASS: description, performance and astronomical results
Ian Parry, Andrew Bunker, Andrew Dean +9
The Cambridge Infra-red Panoramic Survey Spectrograph (CIRPASS) is described. This near-infrared (NIR) spectrograph has been used on the 8m Gemini-South Telescope, the 3.9m Anglo-A…
A Matched Catalogue i-dropout galaxies at z~6 in the Hubble Ultra Deep Field
Andrew J Bunker, Elizabeth R. Stanway
A recent preprint by Yan & Windhorst (astro-ph/0407493) independently repeats our selection of candidate z~6 galaxies in the Hubble Ultra Deep Field (astro-ph/0403223). The agreeme…
Star Formation at Redshift One: Preliminary results from an H-alpha Survey
M. Doherty, A. Bunker, R. Sharp +5
We present the first successful demonstration of multi-object near-infrared spectroscopy on high redshift galaxies. Our objective is to address the true star formation history of t…
CIRPASS near-infrared integral-field spectroscopy of massive star clusters in the starburst galaxy NGC 1140
R. de Grijs, L. J. Smith, A. Bunker +6
[ABRIDGED] We analyse near-infrared integral field spectroscopy of the central starburst region of NGC 1140, obtained at the Gemini-South telescope equipped with CIRPASS. Our ~1.45…
Near-Infrared Properties of I-Drop Galaxies in the Hubble Ultra Deep Field
Elizabeth Stanway, Richard McMahon, Andrew Bunker
We analyse near-infrared HST/NICMOS F110W (J) and F160W (H) band photometry of a sample of 27 i'-drop candidate z~6 galaxies in the central region of the HST/ACS Ultra Deep Field (…
