Wide-band Profile Domain Pulsar Timing Analysis
L. Lentati, M. Kerr, S. Dai +22
We extend profile domain pulsar timing to incorporate wide-band effects such as frequency-dependent profile evolution and broadband shape variation in the pulse profile. We also in…
Spherically-symmetric solutions in general relativity
Do Young Kim, Anthony N. Lasenby, Michael P. Hobson
We present a tetrad-based method for solving the Einstein field equations for spherically-symmetric systems and compare it with the widely-used Lemaître-Tolman-Bondi (LTB) model. I…
AMI observations of ten CLASH galaxy clusters: SZ and X-ray data used together to determine cluster dynamical states
Clare Rumsey, Malak Olamaie, Yvette C. Perrott +7
Using Arcminute Microkelvin Imager (AMI) SZ observations towards ten CLASH clusters we investigate the influence of cluster mergers on observational galaxy cluster studies. Althoug…
Friedmann-Robertson-Walker models do not require zero active mass
Do Young Kim, Anthony N. Lasenby, Michael P. Hobson
The cosmological model has received considerable attention in recent years owing to claims that it is favoured over the standard cold dark matter (CDM) model by m…
Planck intermediate results. XLII. Large-scale Galactic magnetic fields
Planck Collaboration, R. Adam, P. A. R. Ade +175
Recent models for the large-scale Galactic magnetic fields in the literature have been largely constrained by synchrotron emission and Faraday rotation measures. We use three diffe…
