Unknown Ionization Sources in Local Dwarf Galaxies

speaker: Shun Hatano

Abstract:
We reconstruct ionizing spectra of dwarf galaxies in 13.6 — 100 eV range, exploiting Umeda+22 method. We compare this ionizing spectra with black hole (BH) disk models of Kawaguchi 03. We find that ionizing spectra of some dwarf galaxies can be explained by the BH disk models with BH masses of 1e3-1e5 Mo.
