| contents | Nuclear to host galaxy relation of high redshift quasars J. K. Kotilainen Física, Astronomía y Matemáticas Galaxies: active quasars: general infrared: galaxies galaxies: evolution We present near-infrared imaging of quasars at 1 < z < 2, covering a large range (~ 4 mag) of quasar luminosityfunction. The host galaxies of both radio-loud (RLQ) and radio-quiet (RQQ) quasars have luminosities in therange of massive inactive ellipticals, between L* and 10 L*. RLQ hosts are more luminous than RQQ hosts.This luminosity gap is independent of rest-frame U-band luminosity but correlated with rest-frame R-bandluminosity. This color difference between RLQs and RQQs is likely a combination of an intrinsic difference in their SEDs, and a selection effect due to internal dust extinction. There is a reasonable correlation between thenuclear and host luminosities for RLQs but not for RQQs. If the R-band traces the bolometric luminosity, and if the host luminosity is proportional to the black hole mass, high redshift quasars emit with a narrow range of power with respect to their Eddington luminosity. 2008 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57103255 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.32 |
