Abstract:
We present a multiwavelength study of the poor cluster RX J1117.4+0743
([VMF98] 097) at z=0.485, based on GMOS/Gemini South g' and r'
photometry and spectroscopy, and XMM-Newton observations. We examine
its nature and surroundings by analyzing the projected galaxy
distribution, the galaxy velocity distribution, the weak-lensing mass
reconstruction, and the X-ray spectroscopy and imaging.
Description:
The cluster was imaged through the r' and g' Sloan filters in 2003
March and May, using the detector array formed by three 2048x4608
pixels EEV CCDs; the spectra of the galaxies were obtained with GMOS
in 2003 May 29-30.
This object was observed by XMM-Newton in 2002 December (ObsID
082340101) and twice in 2004 June 2004 (ObsIDs 203560201 and
203560401). For XMM-Newton Observations, we have used only MOS1
and PN cameras of the 2002 observations, and only the MOS1 of the
2004 observations.
