Bulk Motions in Large-Scale Void Models

To explain the puzzling situation in the observed bulk flows on scales ∼ 150h Mpc (H0 = 100h −1 km sec Mpc), we consider the observational behavior of spherically symmetric inhomogeneous cosmological models, which consist of inner and outer homogeneous regions connected by a shell or an intermediate self-similar region. It is assumed that the present matter density parameter in the inner region...

Large-scale peculiar motions and cosmic acceleration

Observers with small, but finite, peculiar velocities relative to the Hubble flow can measure a negative deceleration parameter, although the universe may be actually decelerating. The effect is local but it can affect large enough scales to give the impression that the whole universe had recently entered an accelerated phase. We outline the key features of the accelerating mechanism and discus...

The trails of superluminal jet components in 3C 111

In 1996 a major radio flux density outburst occurred in the broad-line radio galaxy 3C 111. It was followed by a particularly bright plasma ejection associated with a superluminal jet component, which has shaped the parsec-scale structure of 3C 111 for almost a decade. Here we present results from 18 epochs of Very Long Baseline Array (VLBA) observations conducted since 1995 as part of the VLBA...

Cloud Clusters and Large-Scale Vertical Motions in the Tropics

The sensible heat budget of a large-scale area containing an idealized tropical cloud cluster is analyzed. The cluster is assumed to have spatial dimensions and precipitation rates typical of observed cloud clusters. In its early stages of development the idealized cluster consists of isolated deep precipitating convective cells, or "hot towers." A simple model using the assumed precipitation r...

Large-scale Motions in the Universe: Observations and Simulations

The peculiar radial velocities of eight clusters of galaxies, as determined from a variety of distance indicators, are consistent with a bulk flow not greatly different in direction and magnitude from the velocity vector of the Local Group relative to the microwave background radiation. The bulk flow vector is directed to l = 266 ± 18, b = 17 ± 15 with a magnitude of 788 ± 113 km s. N-body simu...
