The LCO/Palomar 10,000 km/sec Cluster Survey. II. Constraints on Large-Scale Streaming

Jeffrey A. Willick

The LCO/Palomar 10,000 km/sec (LP10K) Tully-Fisher (TF) data set is used to test for bulk streaming motions on a ~150 Mpc scale. The sample consists of 172 cluster galaxies in the…

POTENT Reconstruction from Mark III Velocities

A. Dekel, A. Eldar, T. Kolatt +5

We present an improved POTENT method for reconstructing the velocity and mass density fields from radial peculiar velocities, test it with mock catalogs, and apply it to the Mark I…

The `Rabbit': A Potential Radio Counterpart of GeV J1417-6100

Mallory S. E. Roberts, Roger W. Romani, Simon Johnston +1

We have mapped the radio emission in the error ellipse of GeV J1417-6100 (2EGS J1418-6049) at 13cm and 20cm using the Australia Telescope Compact Array. We find a large shell with…

A Model of the Double Magnetic Cycle of the Sun

E. E. Benevolenskaya

It has been argued that the solar magnetic cycle consists of two main periodic components: a low-frequency component (Hale's 22-year cycle) and a high-frequency component (quasi-bi…

SHELLFLOW: The First Homogeneous All-Sky TF Survey at 6000 km/s

S. Courteau, J. Willick, M. Strauss +2

We present a new optical Tully-Fisher (TF) investigation for a complete, full-sky sample of 297 Sb-Sc spirals with redshifts between 4500 and 7000 km/s. The survey was specifically…
