The Alignments of the Galaxy Spins with the Real-Space Tidal Field Reconstructed from the Two Mass Redshift Survey
Jounghun Lee, Pirin Erdogdu
We report a direct observational evidence for the existence of the galaxy spin alignments with the real space tidal field. We calculate the real space tidal field from the real spa…
Scale-dependent Galaxy Bias
Peter Coles, Pirin Erdogdu
We present a simple heuristic model to demonstrate how feedback related to the galaxy formation process can result in a scale-dependent bias of mass versus light, even on very larg…
Reconstructed Density and Velocity Fields from the 2MASS Redshift Survey
Pirin Erdogdu, Ofer Lahav, John P. Huchra +13
We present the reconstructed real-space density and the predicted velocity fields from the Two Mass Redshift Survey (2MRS). The 2MRS is the densest all-sky redshift survey to date…
The Dipole Anisotropy of the 2mass Redshift Survey
P. Erdogdu, J. P. Huchra, O. Lahav +14
We estimate the flux weighted acceleration on the Local Group (LG) from the near-infrared Two Micron All Sky Redshift Survey (2MRS). The near-infrared flux weighted dipoles are ver…
The Dipole Anisotropy of the 2 Micron All-Sky Redshift Survey
P. Erdogdu, J. P. Huchra, O. Lahav +14
We estimate the acceleration on the Local Group (LG) from the Two Micron All Sky Redshift Survey (2MRS). The sample used includes about 23,200 galaxies with extinction corrected ma…
The 2dF Galaxy Redshift Survey: Wiener Reconstruction of the Cosmic Web
Pirin Erdogdu, Ofer Lahav, Saleem Zaroubi +27
We reconstruct the underlying density field of the 2 degree Field Galaxy Redshift Survey (2dFGRS) for the redshift range 0.035<z<0.200 using the Wiener Filtering method. The Wiener…
