The population of variable stars in M54 (NGC6715) [PDF]
Monthly Notices of the Royal Astronomical Society, 2010 We present new B, V and I CCD time-series photometry for 177 variable stars in a 13'X 13' field centered on the globular cluster M54 (lying at the center of the Sagittarius dwarf spheroidal galaxy), 94 of which are newly identified variables.

The Candidate Intermediate-Mass Black Hole in the Globular Cluster M54 [PDF]
The Astronomical Journal, 2011 Ibata et al. reported evidence for density and kinematic cusps in the Galactic globular cluster M54, possibly due to the presence of a 9400 solar-mass black hole.

The cosmological Lithium problem outside the Galaxy: the Sagittarius globular cluster M54 [PDF]
Monthly Notices of the Royal Astronomical Society, 2014 The cosmological Li problem is the observed discrepancy between Li abundance, A(Li), measured in Galactic dwarf, old and metal-poor stars (traditionally assumed to be equal to the initial value A(Li)_0), and that predicted by standard Big Bang ...

The nucleus of the Sagittarius dSph galaxy and M54: a window on the process of galaxy nucleation [PDF]
The Astronomical Journal, 2008 We present the results of a thorough study of the nucleus of the Sgr dwarf spheroidal galaxy and of the bright globular cluster M54 that resides within the same nucleus (Sgr,N).

The Dark Matter Halo of M54 [PDF]
The Astrophysical Journal, 2022 M54 is a prototype for a globular cluster embedded in a dark matter halo. Gaia Early Data Release 3 photometry and proper motions separate the old, metal-poor stars from the more metal-rich and younger dwarf galaxy stars.

Investigation on Flavescence Dorée in North-Western Italy Identifies Map-M54 (16SrV-D/Map-FD2) as the Only Phytoplasma Genotype in Vitis vinifera L. and Reveals the Presence of New Putative Reservoir Plants. [PDF]
Biology (Basel), 2023 Simple Summary Flavescence dorée is one of the most important diseases of grapevines. It is associated with phytoplasmas, pathogenic bacteria transmitted from vine to vine by the insect vector Scaphoideus titanus.

Discovery of Blue Hook Stars in the Massive Globular Cluster M54 [PDF]
The Astrophysical Journal, 2003 We present BV photometry centered on the globular cluster M54 (NGC 6715). The color-magnitude diagram clearly shows a blue horizontal branch extending anomalously beyond the zero age horizontal branch theoretical models.

M54 + SAGITTARIUS = ω CENTAURI [PDF]
The Astrophysical Journal, 2010 We derive homogeneous abundances of Fe, O, Na, and α-elements from high-resolution FLAMES spectra for 76 red giant stars in NGC 6715 (M54) and for 25 red giants in the surrounding nucleus of the Sagittarius (Sgr) dwarf galaxy.
