ISAAC images of Abell 1835

SAAC image in the near-infrared of the core of the lensing cluster Abell 1835 (upper) with the location of the galaxy Abell 1835 IR1916 (white circle). The thumbnail images at the bottom show the images of the remote galaxy in the visible R-band (HST-WFPC image) and in the J-, H-, and K-bands. The fact that the galaxy is not detected in the visible image but present in the others - and more so in the H-band - is an indication that this galaxy has a redshift around 10. Note: Since these results have been published several further investigations by several independent teams have been undertaken. A deep observation with the Gemini-North Near-Infrared Imager (NIRI) has not detected the source to fainter magnitude limits than in the ISAAC data. Also, a deep V-band image taken with FORS does not show the object to be present. The status of this object is hence currently unresolved.
