Peculiar velocities into the next generation: cosmological parameters from the SFI++ survey (2009)
Abate, Alexandra, Erdogdu, Pirin
We present cosmological parameter constraints from the SFI++ galaxy peculiar velocity survey, the largest galaxy peculiar velocity sample to date. The analysis is performed by using the gridding...
Shear-Selected Clusters From the Deep Lens Survey III: Masses from Weak Lensing (2009)
Abate, Alexandra, Wittman, D., Margoniner, V. E., Bridle, S. L., Gee, Perry, Tyson, J. Anthony, ...
We present weak lensing mass estimates of seven shear-selected galaxy cluster candidates from the Deep Lens Survey. The clusters were previously identified as mass peaks in convergence maps of 8.6...
The Three Faces of Omega_m: Testing Gravity with Low and High Redshift SN Ia Surveys (2008)
Peculiar velocities of galaxies hosting Type Ia supernovae generate a significant systematic effect in deriving the dark energy equation of state w, at level of a few percent. Here we illustrate how...
Abate, Alexandra, Bridle, Sarah, Teodoro, Luis F. A., Warren, Michael S., Hendry, Martin
We investigate methods to best estimate the normalisation of the mass density fluctuation power spectrum (sigma_8) using peculiar velocity data from a survey like the Six degree Field Galaxy Velocity...
