TBPos: Dataset for Large-Scale Precision Visual Localization
Masud Fahim, Ilona Söchting, Luca Ferranti +2
Image based localization is a classical computer vision challenge, with several well-known datasets. Generally, datasets consist of a visual 3D database that captures the modeled s…
Intervening Mg II absorption systems from the SDSS DR12 quasar spectra
Srinivasan Raghunathan, Roger G. Clowes, Luis E. Campusano +3
We present the catalogue of the Mg II absorption systems detected at a high significance level using an automated search algorithm in the spectra of quasars from the twelfth data r…
On the relation between Seyfert 2 accretion rate and environment at z < 0.1
Georgina V. Coldwell, Sebastian Gurovich, Jorge Diaz Tello +2
We analyse different properties of the small scale environment of Seyfert 2 for two samples selected according to the accretion rate parameter, R, from the DR7-SDSS survey. We comp…
Environments of Strong / Ultrastrong, Ultraviolet Fe II Emitting Quasars
Roger G. Clowes, Srinivasan Raghunathan, Ilona K. Soechting +2
We have investigated the strength of ultraviolet Fe II emission from quasars within the environments of Large Quasar Groups (LQGs) in comparison with quasars elsewhere, for 1.1 <=…
A structure in the early universe at z ~ 1.3 that exceeds the homogeneity scale of the R-W concordance cosmology
Roger G. Clowes, Kathryn A. Harris, Srinivasan Raghunathan +3
A Large Quasar Group (LQG) of particularly large size and high membership has been identified in the DR7QSO catalogue of the Sloan Digital Sky Survey. It has characteristic size (v…
Dichotomy in host environments and signs of recycled AGN
Georgina V. Coldwell, Diego G. Lambas, Ilona K. Soechting +1
We analyse the relation between AGN host properties and large scale environment for a representative red and blue AGN host galaxy sample selected from the DR4 SDSS. A comparison is…
