Effect of Gravitational Lensing on Measurements of the Sunyaev-Zel’dovich Effect
The Sunyaev–Zel’dovich (SZ) effect of a cluster of galaxies is usually measured after background radio sources are removed from the cluster field. Gravitational lensing by the cluster potential leads to a systematic deficit in the residual intensity of unresolved sources behind the cluster core relative to a control field far from the cluster center. As a result, the measured decrement in the R...

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
The Sunyaev - Zeldovich Effect
During passage through a cluster of galaxies some of the photons of the cosmic microwave background (CMB) radiation are scattered by electrons in the hot intracluster (IC) gas. The scattering slightly modifies the incident Planck spectrum, imprinting on it a unique spectral signature that was first described by Sunyaev & Zeldovich (1972). [The impact of hypothetical hot intergalactic gas on the...
