Planck Intermediate Results II: Comparison of Sunyaev-Zeldovich measurements from Planck and from the Arcminute Microkelvin Imager for 11 galaxy clusters
Planck, AMI Collaborations, : +195
A comparison is presented of Sunyaev-Zeldovich measurements for 11 galaxy clusters as obtained by Planck and by the ground-based interferometer, the Arcminute Microkelvin Imager. A…
The XMM Cluster Survey: Evidence for energy injection at high redshift from evolution of the X-ray luminosity-temperature relation
Matt Hilton, A. Kathy Romer, Scott T. Kay +21
We measure the evolution of the X-ray luminosity-temperature (L_X-T) relation since z~1.5 using a sample of 211 serendipitously detected galaxy clusters with spectroscopic redshift…
Planck Intermediate Results. IV. The XMM-Newton validation programme for new Planck galaxy clusters
Planck Collaboration, P. A. R. Ade, N. Aghanim +191
We present the final results from the XMM-Newton validation follow-up of new Planck galaxy cluster candidates. We observed 15 new candidates, detected with signal-to-noise ratios b…
Observational constraints on K-inflation models
Sheng Li, Andrew R. Liddle
We extend the ModeCode software of Mortonson, Peiris and Easther to enable numerical computation of perturbations in K-inflation models, where the scalar field no longer has a cano…
Planck intermediate results. III. The relation between galaxy cluster mass and Sunyaev-Zeldovich signal
Planck Collaboration, P. A. R. Ade, N. Aghanim +183
We examine the relation between the galaxy cluster mass M and Sunyaev-Zeldovich (SZ) effect signal D_A^2 Y for a sample of 19 objects for which weak lensing (WL) mass measurements…
The XMM Cluster Survey: The interplay between the brightest cluster galaxy and the intra-cluster medium via AGN feedback
John P. Stott, Ryan C. Hickox, Alastair C. Edge +16
Using a sample of 123 X-ray clusters and groups drawn from the XMM-Cluster Survey first data release, we investigate the interplay between the brightest cluster galaxy (BCG), its b…
