  1. 1. Lyman Continuum Radiation from Intermediate-Mass Black Holes : An Estimation of the Contribution of LyC Radiation from IMBHs in z~3 Galaxies

    University essay from Uppsala universitet/Observationell astrofysik

    Keywords : intermediate-mass black holes; cosmic reionization; high-redshift galaxies;

    Abstract : This thesis concerns the cosmic reionization of the intergalactic medium in the high redshift universe and, in particular, is a first approach to examine what role intermediate mass black holes (IMBHs) play in this cosmic age. Unexpectedly high values of hydrogen ionizing radiation, compared to current models, have been reported from galaxies at redshift ~3 (used as stand-ins for galaxies at the age of reionization), and thus these models need revision, potentially by adding effects of IMBH content in the galaxies.
