CFHTLenS: Weak lensing calibrated scaling relations for low mass clusters of galaxies

Understand

We present weak lensing and X-ray analysis of 12 low mass clusters from the CFHTLenS and XMM-CFHTLS surveys.

• We combine these systems with high-mass systems from CCCP and low-mass systems from COSMOS to obtain a sample of 70 systems, spanning over two orders of magnitude in mass.
• We measure core-excised Lx-Tx, M-Lx and M-Tx scaling relations and include corrections for observational biases.
• By providing fully bias corrected relations, we give the current limitations for Lx and Tx as cluster mass proxies.
