The formation and assembly history of the Milky Way revealed by its globular cluster population (2018, background): “…with Canis Major (both of which have recently been accreted by the Milky Way and possibly correspond to Satellites 2 and 3, see Section 5.1) are consistent with the enrichment histories derived for Satellites 2 and 3 (see e.g. Layden & Sarajedini 2000; Forbes et al. 2004; Siegel et al. 2007).”
Galactic Halo Substructure in the Sloan Digital Sky Survey: The Ancient Tidal Stream from the Sagittarius Dwarf Galaxy (2000, background): “In the main body of the Sagittarius dwarf galaxy, blue horizontal branch stars make up a much higher fraction of the total stellar population in its globular clusters than in its field stars (Layden & Sarajedini 2000).”
Galactic stellar haloes in the CDM model (2009, background): “Support for this conclusion includes the presence of five globular clusters in the Fornax dwarf spheroidal (Hodge 1961) and the association of several Galactic clusters with the Sagittarius nucleus and debris (e.g. Layden & Sarajedini 2000; Newberg et al. 2003; Bellazzini et al. 2003).”

An Abundance Analysis of Bright Giants in the Globular Cluster NGC 1851 (2007, background): “…a large metallicity spread and are the two most massive Galactic globular clusters. q Centauri is widely regarded as the nucleus of an accreted dwarf galaxy (e.g., Smith et al. 2000), and M54 is suspected to be the nucleus of the Sagittarius dwarf spheroidal galaxy (e.g., Layden & Sarajedini 2000).”
Accreted versus in situ Milky Way globular clusters (2010, background): “Note, that in some cases the relative age is greater than the normalisation value, with the oldest absolute age in their sample being 14.46 Gyr (albeit with a large error of ± 1.8 Gyrs).”
A Matched-Filter Analysis of the Tidal Tails of the Globular Cluster Palomar 5 (2002, background): “…at a magnitude where the photometric scatter in color is large, but it is close to the color of the halo turnoff as expected from the best-fit age and metallicity of Layden & Sarajedini (2000) and from comparison with CMDs of the Sagittarius dSph from the literature (Martı́nez-Delgado et al. 2001).”

A Two Micron All Sky Survey View of the Sagittarius Dwarf Galaxy. I. Morphology of the Sagittarius Core and Tidal Arms (2003, methodology): “M-giant escape would be enhanced were the most recent starburst spread out over a rotating disk rather than in a nuclear concentration.8 It is also possible that the starburst itself may have contributed to the destruction of Sgr. Starburst-driven galactic winds have been evoked to explain a number ”
From Supermassive Black Holes to Dwarf Elliptical Nuclei: A Mass Continuum (2006, background): “…6715,q Cen, or M31-G1, are thought to be the relic nuclei of satellite dE,N galaxies that have been tidally stripped and absorbed by their bigger parents (e.g., Freeman 1993; Zinnecker et al. 1988; Layden & Sarajedini 2000; Majewski et al. 2000; Meylan et al. 2001; McWilliam & Smecker-Hane 2005).”
Comparing the properties of local globular cluster systems: implications for the formation of the Galactic halo (2004, methodology): “M54is coeval with Terzan 8 (Layden & Sarajedini 2000), but given the uncertainty of its measured abundance, and the possibility of an internal metallicity spread (Da Costa & Armandroff 1995), its position in Fig.”
THE CHEMICAL EVOLUTION OF THE DRACO DWARF SPHEROIDAL GALAXY (2009, background): “During the process of accretion Pal 12 was presumably stripped from the Sgr dSph to become part of the extended Sgr stream; Layden & Sarajedini (2000) suggest several other Milky Way globular clusters were also stripped from the Sgr dSph, one of which is Terzan 7.”
GLOBULAR CLUSTERS IN THE OUTER GALACTIC HALO: NEW HUBBLE SPACE TELESCOPE/ADVANCED CAMERA FOR SURVEYS IMAGING OF SIX GLOBULAR CLUSTERS AND THE GALACTIC GLOBULAR CLUSTER AGE–METALLICITY RELATION (2011, unknown): “It has already been demonstrated by Layden & Sarajedini (2000) that the GCs associated with Sgr follow the same trend as its field stars.”
The stellar halo of the Galaxy (2008, background): “One proposed explanation (but not the only one, c.f. Baumgardt et al. 2008, and references therein) is that these might be remaining cores of disrupted nucleated dwarf galaxies, as is the case for M54 which is located in the Sagittarius dwarf itself (Layden & Sarajedini 2000).”
Globular Cluster Systems in Brightest Cluster Galaxies: Bimodal Metallicity Distributions and the Nature of the High-Luminosity Clusters (2005, background): “The massive cluster NGC 6715 forms the nucleus of the Sagittarius dwarf elliptical (Layden & Sarajedini 2000), and the extended structure and multicomponent population within ω Centauri have raised suggestions that it might be the relic nucleus of a former dE satellite of the Milky Way (e.g.…”
Galaxy Threshing and the Formation of Ultracompact Dwarf Galaxies (2001, unknown): “A growing number of evidence supporting this scenario has been accumulating for the case ofq Cen and M54 (e.g., Majewski et al. 2000; Layden & Sarajedini 2000; van den Bergh 2000).”
Extragalactic Globular Clusters and Galaxy Formation (2006, background): “Together these results suggest star formation histories that were at least moderately bursty (e.g., Layden & Sarajedini 2000).”
