The 2dF BL Lac Survey II
D. Londish, S. M. Croom, J. Heidt +6
We report on our further analysis of the expanded and revised sample of potential BL Lac objects (the 2BL) optically identified from two catalogues of blue-selected (UV excess) poi…
2QZJ215454.3-305654: a radio-quiet BL Lac object or lineless QSO?
D. Londish, J. Heidt, B. J. Boyle +2
High signal-to-noise spectroscopy has established a redshift of z=0.494 for the source 2QZJ215454.3-305654, originally selected from the 2dF/6dF QSO Redshift Surveys as one of 45 c…
The 2dF BL Lac Survey
D. Londish, S. M. Croom, B. J. Boyle +7
We have optically identified a sample of 56 featureless continuum objects without significant proper motion from the 2dF QSO Redshift Survey (2QZ). The steep number--magnitude rela…
The spectral characteristics of the 2dFGRS-NVSS galaxies
C A Jackson, D M Londish
We have analysed the 2dF spectra of a sample of galaxies common to the 2dF galaxy redshift survey (2dFGRS, Colless 1999) and the NRAO VLA sky survey (NVSS, Condon et al. 1998). Our…
The Space Density of low redshift AGN
D. Londish, B. J. Boyle, D. J. Schade
We present a new determination of the optical luminosity function (OLF) of active galactic nuclei (AGN) at low redshifts (z<0.15) based on Hubble Space Telescope (HST) observations…
