Interesting Evidence for a Low-Level Oscillation Superimposed on the Local Hubble Flow
Morley B Bell
Historically the velocity scatter seen on local Hubble plots has been attributed to the peculiar velocities of individual galaxies. Although most galaxies also have uncertainties i…
On The Depolarization Asymmetry Seen in Giant Radio Lobes
M. B. Bell, S. P. Comeau
The depolarization asymmetry seen in double-lobed radio sources, referred to as the Laing-Garrington (L-G) effect where more rapid depolarization is seen in the lobe with no visibl…
Comet-like mineralogy of olivine crystals in an extrasolar proto-Kuiper belt
B. L. de Vries, B. Acke, J. A. D. L. Blommaert +20
Some planetary systems harbour debris disks containing planetesimals such as asteroids and comets. Collisions between such bodies produce small dust particles, the spectral feature…
Extragalactic number counts at 100 um, free from cosmic variance
B. Sibthorpe, R. Ivison, R. J. Massey +4
We use data from the Disc Emission via a Bias-free Reconnaissance in the Infrared/Submillimetre (DEBRIS) survey, taken at 100 um with the Photoconductor Array Camera and Spectromet…
A Possible Divot in the Size Distribution of the Kuiper Belt's Scattering Objects
C. Shankman, B. Gladman, N. Kaib +2
Via joint analysis of a calibrated telescopic survey, which found scattering Kuiper Belt objects, and models of their expected orbital distribution, we measure the form of the scat…
Resolved Debris Discs Around A Stars in the Herschel DEBRIS Survey
Mark Booth, Grant Kennedy, Bruce Sibthorpe +12
The majority of debris discs discovered so far have only been detected through infrared excess emission above stellar photospheres. While disc properties can be inferred from unres…
