On q-analogue of Bernstein-Schurer-Stancu operators

Keywords: q-Bernstein–Schurer–Stancu operators q-integers Modulus of smoothness Rate of convergence a b s t r a c t In the present paper, we introduce the Stancu type generalization of the Bernstein–Schurer operators based on q integers. First, we prove the basic convergence of S ða;bÞ n;p ð:; q; xÞ and then obtain the rate of convergence by these operators in terms of the modulus of continuity...

The Cluster Sz — Mass Correlation

N-body + hydrodynamic simulations of galaxy clusters are used to demonstrate a correlation between galaxy cluster mass and the strength of the Sunyaev–Zel’dovich (SZ) effect induced by the cluster. The intrinsic scatter in the correlaton is larger than seen in the cluster mass — X–ray temperature correlation, but smaller than seen in the correlation between mass (or temperature) and X–ray lumin...

New Territory: SZ Cluster Surveys

The potential of the Sunyaev-Zel’dovich (SZ) effect for cluster studies has long been appreciated, although not yet fully exploited. Recent technological advances and improvements in observing strategies have changed this, to the point where it is now possible to speak of this subject at a meeting devoted to surveys in Cosmology. We will discuss SZ surveys by distinguishing what may be called p...
