Research Highlights: 

Prior to joining KIAA, Luis Ho was a Staff Astronomer for 15 years at the Observatories of the Carnegie Institution for Science.  His research covers a wide range of different, but interrelated areas, using all available observational techniques spanning from radio to X-ray energies.  He actively uses ground-based telescopes and space-based astronomical satellites. The main topics of his research, published in over 350 refereed papers,  include: (1) active galaxies and quasars, including the physics of emission-line regions, accretion disks, jets, and host galaxies; (2) searches for massive black holes, from star clusters to the centers of galaxies; (3) coevolution of black holes and galaxies, black hole scaling relations, and AGN feedback; (4) galaxy structure and the origin of the Hubble sequence; (5) extragalactic star formation; and (6) the interstellar medium.
