A Comparison of Algorithms for the Construction of SZ Cluster Catalogues
J. -B. Melin, N. Aghanim, M. Bartelmann +20
We evaluate the construction methodology of an all-sky catalogue of galaxy clusters detected through the Sunyaev-Zel'dovich (SZ) effect. We perform an extensive comparison of twelv…
Localized Energetics of Linear Gravity: Theoretical Development
Luke M. Butcher, Michael Hobson, Anthony Lasenby
We recently developed a local description of the energy, momentum and angular momentum carried by the linearized gravitational field, wherein the gravitational energy-momentum tens…
Localizing the Angular Momentum of Linear Gravity
Luke M. Butcher, Anthony Lasenby, Michael Hobson
In a previous article [Phys. Rev. D 82 104040 (2010)], we derived an energy-momentum tensor for linear gravity that exhibited positive energy density and causal energy flux. Here w…
AMI SZ observations and Bayesian analysis of a sample of six redshift-one clusters of galaxies
AMI Consortium, :, Michel P. Schammel +15
We present 16-GHz Sunyaev-Zel'dovich observations using the Arcminute Microkelvin Imager (AMI) and subsequent Bayesian analysis of six galaxy clusters at redshift () c…
Hyper-efficient model-independent Bayesian method for the analysis of pulsar timing data
Lindley Lentati, Paul Alexander, Michael P. Hobson +4
A new model independent method is presented for the analysis of pulsar timing data and the estimation of the spectral properties of an isotropic gravitational wave background (GWB)…
Planck Intermediate Results. IX. Detection of the Galactic haze with Planck
Planck Collaboration, P. A. R. Ade, N. Aghanim +181
Using precise full-sky observations from Planck, and applying several methods of component separation, we identify and characterize the emission from the Galactic "haze" at microwa…
