Cosmological constraints from Archeops
A. Benoit, P. Ade, A. Amblard +65
We analyze the cosmological constraints that Archeops places on adiabatic cold dark matter models with passive power-law initial fluctuations. Because its angular power spectrum ha…
Cosmological Constraints from the Cosmic Microwave Background
M. Le Dour, M. Douspis, J. G. Bartlett +1
Using an approximate likelihood method adapted to band--power estimates, we analyze the ensemble of first generation cosmic microwave background anisotropy experiments to deduce co…
An Approximation to the Likelihood Function for Band-Power Estimates of CMB Anisotropies
J. G. Bartlett, M. Douspis, A. Blanchard +1
Band-power estimates of cosmic microwave background fluctuations are now routinely used to place constraints on cosmological parameters. For this to be done in a rigorous fashion,…
X-Ray galaxy clusters: constraints on models of galaxy formation
J. Oukbir, J. G. Bartlett, A. Blanchard
We present a self-consistent approach to the modeling of X-ray clusters of galaxies in a flat universe. Employing the Press and Schechter (1974) formalism to derive the mass functi…
The Sunyaev-Zel'dovich Effect and the Value of Omega
D. Barbosa, J. G. Bartlett, A. Blanchard +1
We consider the Sunyaev-Zel'dovich (SZ) effect as a probe of Omega_o: Using a self-consistent modeling of X-ray clusters, we examine the dependence of both the mean Compton y param…
The Physical State of the Intergalactic Medium or Can We Measure Y?
J. G. Bartlett, D. Barbosa, A. Blanchard
We present an argument for a {\it lower limit} to the Compton- parameter describing spectral distortions of the cosmic microwave background (CMB). The absence of a detectable Gu…
