X-ray and weak lensing measurements of the mass profile of MS 1008.1-1224: Chandra and VLT data.

ETTORI S. and LOMBARDI M.

Abstract (from CDS):

We analyse the Chandra dataset of the galaxy cluster MS 1008.1-1224 to recover an estimate of the gravitating mass as function of the radius and compare these results with the weak lensing reconstruction of the mass distribution obtained from deep FORS1-VLT multicolor imaging. Even though the X-ray morphology is disturbed with a significant excess in the northern direction suggesting that the cluster is not in a relaxed state, we are able to match the two mass profiles both in absolute value and in shape within 1 σ uncertainty and up to 1100h50–1kpc. The recovered X-ray mass estimate does not change by using either the azimuthally averaged gas density and temperature profiles or the results obtained in the northern sector alone where the signal-to-noise ratio is higher.
