Prospects for clustering and lensing measurements with forthcoming intensity mapping and optical surveys
Alkistis Pourtsidou, David Bacon, Robert Crittenden +1
We explore the potential of using intensity mapping surveys (MeerKAT, SKA) and optical galaxy surveys (DES, LSST) to detect HI clustering and weak gravitational lensing of 21cm emi…
CMB lensing tomography with the DES Science Verification galaxies
T. Giannantonio, P. Fosalba, R. Cawthon +101
We measure the cross-correlation between the galaxy density in the Dark Energy Survey (DES) Science Verification data and the lensing of the cosmic microwave background (CMB) as re…
Cross-correlation cosmography with HI intensity mapping
Alkistis Pourtsidou, David Bacon, Robert Crittenden
The cross-correlation of a foreground density field with two different background convergence fields can be used to measure cosmographic distance ratios and constrain dark energy p…
General relativistic corrections to -body simulations and the Zel'dovich approximation
Christian Fidler, Cornelius Rampf, Thomas Tram +3
The initial conditions for Newtonian -body simulations are usually generated by applying the Zel'dovich approximation to the initial displacements of the particles using an init…
Reconstruction of the dark matter-vacuum energy interaction
Yuting Wang, Gong-Bo Zhao, David Wands +2
An interaction between the vacuum energy and dark matter is an intriguing possibility which may offer a way of solving the cosmological constant problem. Adopting a general prescri…
The importance of the cosmic web and halo substructure for power spectra
Francesco Pace, Marc Manera, David J. Bacon +2
In this work we study the relevance of the cosmic web and substructures on the matter and lensing power spectra measured from halo mock catalogues extracted from the N-body simulat…
