The evolution of the galaxy cluster luminosity-temperature relation.

NOVICKI M.C., SORNIG M. and HENRY J.P.

Abstract (from CDS):

We analyzed the luminosity-temperature (L-T) relation for two samples of galaxy clusters that have been observed by the ASCA satellite. We used 32 high-redshift clusters (0.3<z<0.6), 53 low-redshift clusters (z<0.3), and also the combination of the low- and high-redshift data sets. This is one of two surveys to use only ASCA data and has the largest number of high-redshift clusters. We assumed a power-law relation between the bolometric luminosity of the galaxy cluster and its integrated temperature (uncorrected for cooling flows) and redshift [Lbol,44=CTα(1+z)A]. We found that for an ΩM=1.0, ΩΛ=0.0 universe, A=1.134+1.057–1.073±1.66, α=2.815+0.322–0.316±0.42, and logC=-1.167+0.216–0.221±0.25, and for an ΩM=0.3, ΩΛ=0.7 universe, A=2.052+1.073–1.058±1.63, α=2.822+0.320–0.323±0.43, and logC=-1.126+0.223–0.219±0.26 (all errors at 68% confidence for one and two interesting parameters). We found the dispersion at constant kT in this relation to be ΔlogL=0.282 for ΩM=1.0, ΩΛ=0.0, and ΔlogL=0.283 for ΩM=0.3, ΩΛ=0.7. The results for the combined data set and those found using the low- and high-redshift clusters are consistent and independent of cosmology, with previous estimates of L∼T3 found by other authors. The observed weak or zero evolution agrees with the predictions of models that produce L∼T3 incorporating an initial source of nongravitational energy before cluster collapse.:
