We also investigate if intermediate-mass black holes are hosted in the center of these galaxies. In the most interesting case of UMI dwarf, we put an upper limit to the central compact object luminosity of ≃ 4 × 10<SUP>33</SUP> erg s<SUP>-1</SUP>. As the target correlates in position also with a radio source, we estimated a black hole mass of ≃ 32.0<SUB>-2.76</SUB><SUP>+2.54</SUP> × 10<SUP>6</SUP> M<SUB>☉</SUB>.STAMPAenConference paper10.1142/9789813226609_01402-s2.0-85059094329https://www.worldscientific.com/doi/abs/10.1142/9789813226609_01402018mgm..conf.1529NFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
