The C-Band All-Sky Survey (C-BASS): Total intensity point-source detection over the northern sky
R. D. P. Grumitt, Angela C. Taylor, Luke Jew +14
We present a point-source detection algorithm that employs the second order Spherical Mexican Hat wavelet filter (SMHW2), and use it on C-BASS northern intensity data to produce a…
The C-Band All-Sky Survey (C-BASS): Simulated parametric fitting in single pixels in total intensity and polarization
Luke Jew, Angela C. Taylor, Michael E. Jones +14
The cosmic microwave background -mode signal is potentially weaker than the diffuse Galactic foregrounds over most of the sky at any frequency. A common method of separating the…
Numerical estimation of densities
Y. Ascasibar, J. Binney
[Abridged] We present a novel technique, dubbed FiEstAS, to estimate the underlying density field from a discrete set of sample points in an arbitrary multidimensional space. FiEst…
On the formation of cold fronts in massive mergers
H. Mathis, G. Lavaux, J. M. Diego +1
Using adiabatic hydrodynamical simulations, we follow the evolution of two symmetric cold fronts developing in the remnant of a violent z=0.3 massive cluster merger. The structure…
