The effect of foreground subtraction on cosmological measurements from Intensity Mapping
L. Wolz, F. B. Abdalla, C. Blake +3
We model a 21 cm intensity mapping survey in the redshift range 0.01<z<1.5 designed to simulate the skies as seen by future radio telescopes such as the Square Kilometre Array (SKA…
Revisiting the spread spectrum effect in radio interferometric imaging: a sparse variant of the w-projection algorithm
L. Wolz, J. D. McEwen, F. B. Abdalla +2
Next-generation radio interferometric telescopes will exhibit non-coplanar baseline configurations and wide field-of-views, inducing a w-modulation of the sky image, which in turn…
Star/galaxy separation at faint magnitudes: Application to a simulated Dark Energy Survey
M. T. Soumagnac, F. B. Abdalla, O. Lahav +17
We address the problem of separating stars from galaxies in future large photometric surveys. We focus our analysis on simulations of the Dark Energy Survey (DES). In the first par…
The varying w spread spectrum effect for radio interferometric imaging
Laura Wolz, Filipe B. Abdalla, Rafael E. Carrillo +2
We study the impact of the spread spectrum effect in radio interferometry on the quality of image reconstruction. This spread spectrum effect will be induced by the wide field-of-v…
