Comparison of the SFI peculiar velocities with the IRAS 1.2‐Jy gravity field

We present a comparison between the peculiar velocity fields measured from a recently completed l-band Tully–Fisher survey of field spirals (SFI) and that derived from the IRAS 1.2-Jy redshift survey… Expand

ON TESTING THE EQUIVALENCE PRINCIPLE WITH EXTRAGALACTIC BURSTS

- A. Nusser
- Physics
- 14 January 2016

An interesting test of Einstein's equivalence principle (EEP) relies on the observed lag in the arrival times of photons emitted from extragalactic transient sources. Attributing the lag between… Expand

The cosmological bulk flow: consistency with $\Lambda$CDM and $z\approx 0$ constraints on $\sigma_8$ and $\gamma$

- A. Nusser, Marc Davis
- Physics
- 9 January 2011

We derive estimates for the cosmological bulk flow from the SFI++ Tully-Fisher (TF) catalog. For a sphere of radius $40 \hmpc$ centered on the MW, we derive a bulk flow of $333 \pm 38\kms $ towards… Expand

Tracing large-scale fluctuations back in time

A quasi-linear method for recovering the growing mode of the initial fluctuations of a cosmological gravitating system from the present large-scale peculiar velocity or density field is presented and… Expand

Comparison of velocity and gravity fields: the mark III tully-fisher catalog versus the iras 1.2 jy survey

- Marc Davis, A. Nusser, J. Willick
- Physics
- 17 April 1996

We consider a measure of the peculiar velocity field derived from the Mark III compilation of 2900 spiral galaxies (Willick et al.), using an analysis method that is substantially free of bias… Expand

Self-similar spherical collapse with non-radial motions

- A. Nusser
- Physics
- 15 August 2000

We derive the asymptotic mass profile near the collapse center of an initial spherical density perturbation, $\delta \propto M^{-\epsilon}$, of collision-less particles with non-radial motions. We… Expand

Evolution of one-point distributions from Gaussian initial fluctuations

- L. Kofman, E. Bertschinger, J. M. Gelb, A. Nusser, A. Dekel
- Physics
- 11 November 1993

We study the quasilinear evolution of the one-point probability density functions (PDFs) of the smoothed density and velocity fields in a cosmological gravitating system beginning with Gaussian… Expand

Modified Newtonian dynamics of large-scale structure

- A. Nusser
- Physics
- 3 September 2001

We examine the implications of modified Newtonian dynamics (MOND) on the large-scale structure in a Friedmann-Robertson-Walker universe. We employ a 'Jeans swindle' to write a MOND-type relationship… Expand

Local gravity versus local velocity: solutions for β and non-linear bias

- Marc Davis, A. Nusser, K. Masters, C. Springob, J. Huchra, G. Lemson
- Physics
- 13 November 2010

We perform a reconstruction of the cosmological large scale flows in the nearby Universe using two complementary observational sets. The first, the SFI++ sample of Tully-Fisher (TF) measurements of… Expand

Revisiting the NVSS number count dipole

We present a realistic modeling of the dipole component of the projected sky distribution of NVSS radio galaxies. The modeling relies on mock catalogs generated within the context of $\Lambda$CDM… Expand
