EMPRESS. XIV. Strong High-ionization Lines of Young Galaxies at z = 0–8: Ionizing Spectra Consistent with the Intermediate-mass Black Holes with M BH ∼ 103–106 M ⊙

The Astrophysical Journal
We present ionizing spectra estimated at 13.6–100 eV for 10 dwarf galaxies with strong high-ionization lines of He ii λ 4686 and [Ne v ] λ 3426 ([Ne iv ] λ 2424) at z = 0 ( z = 8) that are identified in our Keck/LRIS spectroscopy and the literature (the ...

Black Hole Scaling Relations in the Dwarf-galaxy Regime with Gaia-Sausage/Enceladus and ωCentauri

The Astrophysical Journal Letters
The discovery of fast moving stars in Milky Way’s most massive globular cluster, ω Centauri ( ω Cen), has provided strong evidence for an intermediate-mass black hole (IMBH).

Searching for Intermediate-mass Black Holes in Globular Clusters through Tidal Disruption Events

The Astrophysical Journal
Intermediate-mass black holes (IMBHs) may be the link between stellar mass holes and the supermassive variety in the nuclei of galaxies, and globular clusters (GCs) may be one of the most promising environments for their formation.
