• A unified multiwavelength model of galaxy formation (2015, background): “…a number of studies measuring stellar mass-to-light ratios from stellar dynamics (e.g. Cappellari et al. 2012) or gravitational lensing (e.g. Treu et al. 2010) findM/L increasing with stellar mass, implying an IMF in massive early-type galaxies that is either top-heavy or bottom-heavy…”
• The delay-time distribution of Type Ia supernovae from Sloan II (2012, background): “Evidence has accumulated recently that the most massive elliptical galaxies have ‘bottom-heavy’ IMFs, with low-mass components as steep, or even steeper than, the Salpeter IMF (e.g. Treu et al. 2010; Cappellari et al. 2012; Conroy & van Dokkum 2012).”

• THE STELLAR INITIAL MASS FUNCTION OF ULTRA-FAINT DWARF GALAXIES: EVIDENCE FOR IMF VARIATIONS WITH GALACTIC ENVIRONMENT (2013, background): “…lensing studies of elliptical galaxies appear to favor IMFs that become increasingly bottom-heavy (with IMF slopes similar to or steeper than Salpeter) toward higher galaxy masses (Treu et al. 2010; van Dokkum & Conroy 2011; Cappellari et al. 2012a; Dutton et al. 2012; Conroy & van Dokkum 2012).”

Mass structure and dynamics of early-type lens galaxies beyond z ≃ 0.1 (2011, background): “The excess mass can be provided by low mass stars (as in the case of Salpeter IMF, as advocated by, e.g., van Dokkum & Conroy 2010), or by high mass stars remnants, in the form of neutron star and black holes (Treu et al. 2010; Auger et al. 2010b).”
• Dusty Star Forming Galaxies at High Redshift (2014, result): “Similarly, constraints on the stellarmass to light ratio from kinematics have suggested a similar result (e.g. Auger et al., 2010; Treu et al., 2010; Spiniello et al., 2011; Cappellari et al., 2012, 2013; Brewer et al., 2012; Dutton et al., 2013; Tortora et al., 2013), though we note that increased…”
