Abstract:
We present the first results of a narrow-band photometric study of the
massive galaxy cluster XMMU J2235.3-2557 at z=1.39. We obtained
deep H narrow-band imaging with the Near InfraRed Imager and
Spectrometer on Gemini North, corresponding to Hα emission at
the cluster's redshift. Our sample consists of 82 galaxies within a
radius of ∼500kpc, 10 of which are spectroscopically confirmed
cluster members. 16 galaxies are identified as excess line-emitters.
Description:
We obtained observations of the XMMU J2235.3-2557 galaxy cluster with
the Near InfraRed Imager and Spectrometer (NIRI) on Gemini North.
The data presented in this paper originate from the Gemini programme
GN-2007B-Q-79, observed in queue mode in the period from UT 2007 July
11 to UT 2007 September 30.
