Einstein's legacy in galaxy surveys
(Oxford University Press, 2015)
Non-Gaussianity in the primordial fluctuations that seeded structure formation produces a signal in the galaxy power spectrum on very large scales. This signal contains vital information about the primordial Universe, but ...
Probing the imprint of interacting dark energy on very large scales
(American Physical Society, 2015)
The observed galaxy power spectrum acquires relativistic corrections from light-cone effects, and these corrections grow on very large scales. Future galaxy surveys in optical, infrared and radio bands will probe increasingly ...
The faint radio source population at 15.7 GHz - II. Multi-wavelength properties
(Oxford University Press, 2015)
A complete, flux density limited sample of 96 faint (> 0:5 mJy) radio sources is selected
from the 10C survey at 15.7 GHz in the Lockman Hole. We have matched this sample to a
range of multi-wavelength catalogues, including ...
Nonlinear modulation of the HI power spectrum on ultra-large scales. I
(IOP Science, 2015)
Intensity mapping of the neutral hydrogen brightness temperature promises to provide a three-dimensional view of the universe on very large scales. Nonlinear effects are typically thought to alter only the small-scale ...
Hunting down horizon-scale effects with multi-wavelength surveys
(American Astronomical Society, 2015)
Next-generation cosmological surveys will probe ever larger volumes of the universe, including the largest scales, near and beyond the horizon. On these scales, the galaxy power spectrum carries signatures of local primordial ...
New formulas for the (−2) moment of the photoabsorption cross section, σ−2
(American Physical Society, 2015)
Two new formulas for the (−2) moment of the photoabsorption cross section, σ−2, have been determined,
respectively, from the 1988 photoneutron evaluation of Dietrich and Berman and a mass-dependent symmetry
energy ...
Nonlinear galactic dynamos and the magnetic pitch angle
(American Astronomical Society, 2015)
Pitch angles p of the large-scale magnetic fields B of spiral galaxies have previously been inferred from
observations to be systematically larger in magnitude than predicted by standard mean-field dynamo theory. ...
