The Bulk Motion of Flat Edge-On Galaxies Based on 2MASS Photometry [PDF]

, 2003
We report the results of applying the 2MASS Tully-Fisher (TF) relations to study the galaxy bulk flows. For 1141 all-sky distributed flat RFGC galaxies we construct J, H, K_s TF relations and find that Kron $J_{fe}$ magnitudes show the smallest ...

DESI Peculiar Velocity Survey -- Fundamental Plane [PDF]

The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey aims to measure the peculiar velocities of early and late type galaxies within the DESI footprint using both the Fundamental Plane and optical Tully-Fisher relations.

The peculiar galaxy Mkn 298 revisited with integral field spectroscopy [PDF]

, 2004
Spectroscopic and imaging data of the peculiar galaxy Mkn 298 are presented. Narrow-band Hα and broad-band R images are used to study the star formation rate in the galaxy and its morphology, which is typical of a merging system.

Phase-Space Correlations among Systems of Satellite Galaxies

Galaxies, 2021
Driven by the increasingly complete observational knowledge of systems of satellite galaxies, mutual spatial alignments and relations in velocities among satellites belonging to a common host have become a productive field of research.

The Sloan Great Wall. Rich clusters

, 2010
We present the results of the study of the substructure and galaxy content of ten rich clusters of galaxies in three different superclusters of the Sloan Great Wall.

Galaxy peculiar velocities and evolution-bias [PDF]

, 2007
Galaxy bias can be split into two components: a formation-bias based on the locations of galaxy creation, and an evolution-bias that details their subsequent evolution. In this letter we consider evolution-bias in the peaks model.

Using galaxy pairs as cosmological tracers

, 2012
The Alcock-Paczynski (AP) effect uses the fact that, when analyzed with the correct geometry, we should observe structure that is statistically isotropic in the Universe.

Complementarity of Weak Lensing and Peculiar Velocity Measurements in Testing General Relativity [PDF]

, 2010
We explore the complementarity of weak lensing and galaxy peculiar velocity measurements to better constrain modifications to General Relativity. We find no evidence for deviations from GR on cosmological scales from a combination of peculiar velocity ...

Peculiar Galaxies and Radio Sources

Science, 1966
Pairs of radio sources which are separated by from 2° to 6° on the sky have been investigated. In a number of cases peculiar galaxies have been found approximately midway along a line joining the two radio sources. The central peculiar galaxies belong mainly to a certain class in the recently compiled Atlas of Peculiar Galaxies

The Peculiar Galaxy NGC7332

, 2002
We present a detailed study of the edge-on S0 galaxy NGC7332. We show that this object lies significantly below the fundamental plane of early-type galaxies. To understand this behaviour, we have carried out observations with the Integral Field Spectrograph SAURON, which give us a detailed view of the internal kinematics and gas and stars in this ...
