DeepAtlas: a tool for effective manifold learning
Serena Hughes, Timothy Hamilton, Tom Kolokotrones +1
Manifold learning builds on the "manifold hypothesis," which posits that data in high-dimensional datasets are drawn from lower-dimensional manifolds. Current tools generate global…
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…
Nearby quasar remnants and ultra-high energy cosmic rays
Diego F. Torres, Elihu Boldt, Timothy Hamilton +1
As recently suggested, nearby quasar remnants are plausible sites of black-hole based compact dynamos that could be capable of accelerating ultra-high energy cosmic rays (UHECRs).…
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…
