Simulating polarized Galactic synchrotron emission at all frequencies, the Hammurabi code
A. Waelkens, T. Jaffe, M. Reinecke +2
We present a publicly available code called Hammurabi for generating mock polarized observations of Galactic synchrotron emission for telescopes like LOFAR, SKA, Planck and WMAP, b…
Bianchi Type VII_h Models and the WMAP 3-year Data
T. R. Jaffe, A. J. Banday, H. K. Eriksen +2
Context. A specific example of Bianchi Type VIIh models, i.e. those including universal rotation (vorticity) and differential expansion (shear), has been shown in Jaffe et al. (200…
Fast and Efficient Template Fitting of Deterministic Anisotropic Cosmological Models Applied to WMAP Data
T. R. Jaffe, A. J. Banday, H. K. Eriksen +2
We explore methods of fitting templates to cosmic microwave background (CMB) data, and in particular demonstrate the application of the total convolver algorithm as a fast method o…
No Higher Criticism of the Bianchi Corrected WMAP Data
L. Cayon, A. J. Banday, T. Jaffe +4
Motivated by the success of the Bianchi VII_h model in addressing many of the anomalies observed in the WMAP data (Jaffe et al.), we present calculations in real and in wavelet spa…
On the Viability of Bianchi Type VIIh Models with Dark Energy
T. R. Jaffe, S. Hervik, A. J. Banday +1
We generalize the predictions for the CMB anisotropy patterns arising in Bianchi type VIIh universes to include a dark energy component. We consider these models in light of the re…
A determination of the Spectra of Galactic components observed by WMAP
R. D. Davies, C. Dickinson, A. J. Banday +3
WMAP data when combined with ancillary data on free-free, synchrotron and dust allow an improved understanding of the spectrum of emission from each of these components. Here we ex…
Evidence of vorticity and shear at large angular scales in the WMAP data: a violation of cosmological isotropy?
T. R. Jaffe, A. J. Banday, H. K. Eriksen +2
Motivated by the large-scale asymmetry observed in the cosmic microwave background sky, we consider a specific class of anisotropic cosmological models -- Bianchi type VII_h -- and…
X-ray Observations of BL Lacertae During 1997 Outburst and its Association with Quasar-like Characteristics
G. Madejski, M. Sikora, T. Jaffe +3
This paper reports on the X-ray emission from BL Lacertae during its July 1997 outburst as observed with the Rossi X-ray Timing Explorer (RXTE), compares the RXTE data to previous…
