A new method to detect globular clusters with the S-PLUS survey

ABSTRACT In this paper, we describe a new method to select globular cluster (GC) candidates, including galaxy subtraction with unsharp masking, template fitting techniques, and the inclusion of Gaia’s proper motions. We report use 12-band photometric system used by S-PLUS determine radial velocities stellar populations GCs around nearby galaxies. Specifically, assess effectiveness identifying massive galaxies (D < 20 Mpc ? > 200 km s-1) in multiband survey such as using spectroscopically confirmed literature GC candidate lists bright central Fornax cluster, NGC 1399 = 19 Mpc), isolated lenticular 3115 9.4 Mpc). Despite shallow depth, which limits work r 21.3 mag, measure reliable photometry perform robust SED for sample 115 42 3115, recovering velocities, ages, metallicities populations.
