Hamilton's Object -- a clumpy galaxy straddling the gravitational caustic of a galaxy cluster : Constraints on dark matter clumping
Richard E. Griffiths, Mitchell Rudisel, Jenny Wagner +3
We report the discovery of a 'folded' gravitationally lensed image, 'Hamilton's Object', found in a HST image of the field near the AGN SDSS J223010.47-081017.8 (). The len…
Thirty-six New, High-Probability, Damped Ly-alpha Absorbers at Redshift 0.42 < z < 0.70
David A. Turnshek, Eric M. Monier, Sandhya M. Rao +3
Quasar damped Ly-alpha (DLA) absorption line systems with redshifts z<1.65 are used to trace neutral gas over approximately 70 per cent of the most recent history of the Universe.…
Morphologies of low-redshift AGN host galaxies: what role does AGN luminosity play?
Carolin Villforth, Fred Hamann, Anton Koekemoer +7
Mergers of galaxies have been suspected to be a major trigger of AGN activity for many years. However, when compared to carefully matched control samples, AGN host galaxies often s…
Quasar Radio-Loudness and the Elliptical Core Problem
Timothy S. Hamilton
The dichotomy between radio-loud and radio-quiet QSOs is not simply one of host morphology. While spiral galaxies almost exclusively host radio-quiet QSOs, ellipticals can host eit…
