• Yule-Simpson’s paradox in Galactic Archaeology (2019, background): “…(e.g., Minchev et al. 2012, 2014a; Vera-Ciro et al. 2014; Grand et al. 2016, see also discussion in §1), except in redistributing stars heated by external mechanisms (Quinn et al. 1993; Villalobos & Helmi 2008) or turbulent gas clouds at high redshift (Bournaud et al. 2009; Forbes et al. 2012).”
• Radial migration does little for Galactic disc thickening (2012, background): “Preexisting thin discs can be heated fast through the effect of multiple minor mergers (Quinn et al., 1993; Villalobos and Helmi, 2008; Di Matteo et al., 2011), the rate of which decreases with decreasing redshift.”
• Vertical disc heating in Milky Way-sized galaxies in a cosmological context (2015, background): “…of generating a vertically extended distribution of stars in disc galaxies, for example, the accretion of tidally stripped stars from a satellite galaxy (Abadi et al. 2003), and kinematic heating of a pre-existing thin disc as a result of perturbations from satellite galaxies (Quinn et al. 1993).”
• The age structure of stellar populations in the solar vicinity Clues of a two-phase formation history of the Milky Way disk (2013, background): “Heating during the merger epoch (Quinn et al. 1993; Qu et al. 2011; House et al. 2011), or scattering of stars by massive clumps (Bournaud et al. 2009) may have caused additional thickening of the already formed thick stellar component (Quinn et al. 1993; Qu et al. 2011).”
• TRACING CHEMICAL EVOLUTION OVER THE EXTENT OF THE MILKY WAY'S DISK WITH APOGEE RED CLUMP STARS (2014, background): “Some of these mechanisms rely on external events such as satellite heating, accretion, or merger-induced star formation (e.g., Abadi et al. 2003; Quinn et al. 1993; Brook et al. 2004), while others rely on internal evolution of the disk through slow or more rapid dissipational collapse during disk…”
• A Unified, Merger-driven Model of the Origin of Starbursts, Quasars, the Cosmic X-Ray Background, Supermassive Black Holes, and Galaxy Spheroids (2005, background): “…& Mihos 1995) have shown that gravitational torques can drive gas into the centers of these remnants, causing starbursts, similar to what happens in major mergers, leaving behind disturbed remnants with dynamically heated disks (e.g. Quinn et al. 1993; Mihos et al. 1995; Walker et al. 1996).”
• THE SPATIAL STRUCTURE OF MONO-ABUNDANCE SUB-POPULATIONS OF THE MILKY WAY DISK (2011, background): “…direct accretion of stars from a disrupted satellite galaxy (Abadi et al. 2003) or the heating of a pre-existing thin disk through a minor merger (Quinn et al. 1993; Wyse et al. 2006; Kazantzidis et al. 2008; Villalobos & Helmi 2008; Moster et al. 2010), can explain many of the observed…”
• The New Galaxy: Signatures of Its Formation (2002, background): “The present morphology of the thin disk depends on the numbers of small galaxies available to be accreted: a very thin disk is an indication of few accretion events (dark or luminous) after the epoch of disk dissipation and star formation (e.g. Freeman 1987; Quinn et al. 1993; Walker et al. 1996).”
• OXYGEN ABUNDANCES IN NEARBY FGK STARS AND THE GALACTIC CHEMICAL EVOLUTION OF THE LOCAL DISK AND HALO (2013, background): “One of the most accepted scenarios for the formation of the thick-disk involves mergers with satellite galaxies early in the history of the Galactic disk (e.g., Quinn et al. 1993; Walker et al. 1996; Velazquez & White 1999; Abadi et al. 2003; Brook et al. 2004).”
• THICK DISKS OF EDGE-ON GALAXIES SEEN THROUGH THE SPITZER SURVEY OF STELLAR STRUCTURE IN GALAXIES (S4G): LAIR OF MISSING BARYONS?

• Observations of Thick Disks in the Hubble Space Telescope Ultra Deep Field (2006, background): “…a thin disk (Wielen & Fuchs 1985; Fuchs et al. 2001); (2) they arise from sudden heating of thin disk stars during the impact of a smaller galaxy (Quinn et al. 1993; Mihos et al. 1995; Walker et al. 1996; Robin et al. 1996; Velazquez & White 1999; Aguerri et al. 2001); (3) they arise…”
• Oxygen trends in the Galactic thin and thick disks (2003, background): “Thus, at the moment the most plausible formation scenario for the thick disk is a merger event (e.g. Quinn et al. 1993) or an interaction with a companion galaxy (e.g. Kroupa 2002).”
• The Evolution of Gravitationally Unstable Protoplanetary Disks: Fragmentation and Possible Giant Planet Formation (2003, methodology): “To generate the initial conditions we use a modified version of the algorithm written by Hernquist (1993) to construct equilibrium N-body realizations of multicomponent collisionless and gaseous systems under their mutual gravitational potential (see also Quinn et al. 1993).”
