Deep near infrared photometry of new Galactic globular clusters.


Abstract (from CDS):

We present a preliminary report on the first deep infrared photometry of 2MASS GC01 and 2MASS GC02 (GC01 and GC02 hereafter) - new Galactic globular cluster (GC) candidates, discovered by the 2MASS. They both appear to be genuine disk GCs though highly obscured. The location of the two GCs suggests that they are metal rich - [Fe/H]~-0.5. We estimated their distance and reddening using the Ks-band brightness of the red giant branch (RGB) bump, and J-Ks color of the RGB at MK=-3mag: D=3.1±0.5, 3.9±0.6kpc, and AV=20.9±0.7, 17.2±1.2mag, for GC01 and GC02 respectively. Variation in the metal abundance can change our results within 30-35%.
