• Measuring Distance and Properties of the Milky Way’s Central Supermassive Black Hole with Stellar Orbits (2008, background): “This would allow an exploration of a possible cluster of stellar remnants surrounding the central black hole, suggested byMorris (1993),Miralda-Escudé & Gould (2000), and Freitag et al. (2006).”
• AN EXTREMELY TOP-HEAVY INITIAL MASS FUNCTION IN THE GALACTIC CENTER STELLAR DISKS (2009, background): “…from the brightest thermally pulsing AGB stars to the faintest, low mass red clump stars, do not show a central concentration that might resemble a classical equilibrium stellar ’cusp’ as predicted by all theoretical studies (Bahcall & Wolf 1976, 1977; Freitag et al. 2006; Hopman & Alexander 2006).”
• Eccentric Black Hole Gravitational-wave Capture Sources in Galactic Nuclei: Distribution of Binary Parameters (2017, background): “For the Milky Way, as many as ∼20,000 BHs with 10 M each are expected to have segregated into the nucleus (Morris 1993; Miralda-Escudé & Gould 2000; Freitag et al. 2006; Hopman & Alexander 2006).”
• STRONG MASS SEGREGATION AROUND A MASSIVE BLACK HOLE (2008, background): “…are naturally expected to lie in relaxed cores in scenarios where the MBH is formed by run-away mergers in the extreme central density following core collapse (Rees 1984), which occurs on timescales much longer then the relaxation time, TR (e.g. Spitzer 1987; Quinlan 1996; Freitag et al. 2006b,c).”

• AN IMPROVED DISTANCE AND MASS ESTIMATE FOR SGR A* FROM A MULTISTAR ORBIT ANALYSIS (2016, background): “In addition to the central supermassive black hole, a central cluster of stellar mass black holes and/or other compact objects has been predicted and theoretically explored (e.g., Morris 1993; Miralda-Escudé & Gould 2000; Freitag et al. 2006; Merritt 2010).”
• MONITORING STELLAR ORBITS AROUND THE MASSIVE BLACK HOLE IN THE GALACTIC CENTER (2008, methodology): “…Carlo simulations of the GC using the Hénon method and including also stellar collisions and tidal disruptions (M. Freitag, priv. comm.; see also Freitag et al. (2006)) but neglecting star formation yield a rather flat mass density profile of 108(M⊙/pc 3) (r/0.01 pc)−0.5, which translates to η…”
• SECULAR EVOLUTION OF COMPACT BINARIES NEAR MASSIVE BLACK HOLES: GRAVITATIONAL WAVE SOURCES AND OTHER EXOTICA (2012, background): “Assuming standard initial mass functions, in a relaxed model the mass in black holes within 0.01 pc from SgrA* is NBH ≈ 102 (Freitag et al. 2006; Hopman & Alexander 2006a) and Gravitational perturbations will be dominated by stellar black holes.”
• The structure of the nuclear stellar cluster of the Milky Way (2006, background): “The cusp is possibly dominated by stellar black holes (see, e.g., Morris 1993; Miralda-Escudé & Gould 2000; Mouawad et al. 2005; Amaro-Seoane et al. 2004; Freitag et al. 2006; Hopman & Alexander 2006).”
