cds-question@unistra.frsurveysgalaxiesradial-velocityvisible-astronomysloan-photometryWe discuss our targeted search for hypervelocity stars (HVSs), stars traveling with velocities so extreme that dynamical ejection from a massive black hole is their only suggested origin. Our survey, now half-complete, has successfully identified a total of four probable HVSs plus a number of other unusual objects. Here we report the two most recently discovered HVSs: SDSS J110557.45+093439.5 and possibly SDSS J113312.12+010824, traveling with Galactic rest-frame velocities at least +508+/-12 and 418+/-10km/s, respectively.2006ApJ...647..303Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/647/303CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/660/311 : Hypervelocity stars.
