Modified Gravity and Large Scale Flows
Jeremy Mould, Matthew Colless, Pirin Erdogdu +5
Reconstruction of the local velocity field from the overdensity field and a gravitational acceleration that falls off from a point mass as r^-2 yields velocities in broad agreement…
The 6dF Galaxy Survey: Peculiar Velocity Field and Cosmography
Christopher M. Springob, Christina Magoulas, Matthew Colless +6
We derive peculiar velocities for the 6dF Galaxy Survey (6dFGS) and describe the velocity field of the nearby () southern hemisphere. The survey comprises 8885 galaxies fo…
Cosmic Structure and Dynamics of the Local Universe
Francisco-Shu Kitaura, Pirin Erdogdu, Sebastian E. Nuza +4
We present a cosmography analysis of the Local Universe based on the recently released Two-Micron All-Sky Redshift Survey (2MRS). Our method is based on a Bayesian Networks Machine…
The 2MASS Redshift Survey - Description and Data Release
John P. Huchra, Lucas M. Macri, Karen L. Masters +17
We present the results of the 2MASS Redshift Survey (2MRS), a ten-year project to map the full three-dimensional distribution of galaxies in the nearby Universe. The 2 Micron All-S…
Is the misalignment of the Local Group velocity and the 2MASS Redshift Survey dipole typical in a LambdaCDM model?
Pirin Erdogdu, Ofer Lahav
We predict the acceleration of the Local Group generated by the 2MASS Redshift Survey within the framework of LambdaCDM and the halo model of galaxies. We show that as the galaxy f…
Peculiar velocities into the next generation: cosmological parameters from the SFI++ survey
Alexandra Abate, Pirin Erdogdu
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 usin…
