Multiwavelength observations of a rich galaxy cluster at <i>z</i> $\thicksim$ 1
<i>Context. <i/>XMMU J1229+0151 is a rich galaxy cluster with redshift that was serendipitously detected in X-rays within the scope of the XMM-Newton Distant Cluster Project. Both HST/ACS observations in the <i>i<i/><sub>775<sub/> and <i>z<i/><sub>850<sub/> passbands and VLT/FORS2 spectroscopy were obtained, in addition to follow-up Near-Infrared (NIR) imaging in the <i>J<i/>- and …
