Model-independent constraints on dark energy and modified gravity with the SKA
Gong-Bo Zhao, David Bacon, Roy Maartens +2
Employing a nonparametric approach of the principal component analysis (PCA), we forecast the future constraint on the equation of state of dark energy, and on the effective…
Measuring redshift-space distortions with future SKA surveys
Alvise Raccanelli, Philip Bull, Stefano Camera +8
The peculiar motion of galaxies can be a particularly sensitive probe of gravitational collapse. As such, it can be used to measure the dynamics of dark matter and dark energy as w…
Einstein's legacy in galaxy surveys
Stefano Camera, Roy Maartens, Mario G. Santos
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 infor…
Cosmological performance of SKA HI galaxy surveys
S. Yahya, P. Bull, M. G. Santos +4
The Square Kilometre Array (SKA) will conduct the biggest spectroscopic galaxy survey ever, by detecting the 21cm emission line of neutral hydrogen (HI) from around a billion galax…
Blind foreground subtraction for intensity mapping experiments
David Alonso, Philip Bull, Pedro G. Ferreira +1
We make use of a large set of fast simulations of an intensity mapping experiment with characteristics similar to those expected of the Square Kilometre Array (SKA) in order to stu…
Fast simulations for intensity mapping experiments
David Alonso, Pedro G. Ferreira, Mario G. Santos
We present a code to generate mock observations of 21 cm intensity mapping experiments. The emphasis of the code is on reducing the computational cost of running a full-blown simul…
