Detection of Compact Ultraviolet Nuclear Emission in LINER Galaxies
Dan Maoz, Alexei V. Filippenko, Luis C. Ho +4
Low-ionization nuclear emission-line regions (LINERs), which exist in a large fraction of galaxies, may be the least luminous manifestation of quasar activity. The nature of LINERs…
Echo Mappping of the Broad Line Region of AGNs -- A Critical Appraisal
Dan Maoz
The results of recent AGN monitoring campaigns confirm the ``big picture'' of the echo paradigm, but the details of the emission-line light curves cannot be accurately reproduced w…
Galaxy Mergers and Gravitational Lens Statistics
Hans-Walter Rix, Dan Maoz, Edwin L. Turner +1
We investigate the impact of hierarchical galaxy merging on the statistics of gravitational lensing of distant sources. Since no definite theoretical predictions for the merging hi…
A Spectroscopic Method to Measure Macho Proper Motions
Dan Maoz, Andrew Gould
A Massive Compact Halo Object (Macho) that lenses a background star will magnify different parts of the rotating stellar disk by varying amounts. The differential magnification wil…
