Multifrequency Observations of the Gamma-Ray Blazar 3C 279 in Low-State during Integral AO-1

W. Collmar, M. Böttcher, V. Burwitz +19

We report first results of a multifrequency campaign from radio to hard X-ray energies of the prominent gamma-ray blazar 3C 279 during the first year of the INTEGRAL mission. The v…

Discovery of Intergalactic HII Regions

E. V. Ryan-Weber, M. E. Putman, K. C. Freeman +2

We have discovered a number of very small isolated HII regions 20-30 kpc from their nearest galaxy. The HII regions appear as tiny emission line dots (ELdots) in narrow band images…

The dark matter halo of the gravitational lens galaxy 0047-2808

Randall B. Wayth, Rachel L. Webster

The location of the images in a multiple-image gravitational lens system are strongly dependent on the orientation angle of the mass distribution. As such, we can use the location…

2-point Correlation Function of HI-selected Galaxies

S. Tantisrisuk, R. Webster

The 2-point spatial correlation function (CF), , has been used to study the clustering of the galaxies in the preliminary version of the HIPASS Bright Galaxy Catalogue (HIPAS…

Gravitational lensing in galaxy redshift surveys

Daniel J. Mortlock, Rachel L. Webster

Gravitationally-lensed quasars should be discovered as a by-product of large galaxy redshift surveys, being discovered spectroscopically when a low-redshift galaxy exhibits high-re…

Unravelling Active Galactic Nuclei

A. Y. K. N. Oshlack, R. L. Webster, M. J. Drinkwater +3

A complete flat-spectrum radio-loud sample of AGN includes a significant fraction of Seyfert-like AGN including a NLS1. Analysis of their optical spectra suggests that the reddest…
