Abstract
Abstract This Letter reports the discovery of five new globular clusters (GCs) in the Galactic bulge (Camargo 1102, 1103, 1104, 1105, and 1106) using Wide-field Infrared Survey Explorer (WISE) images. Their natures are established by using 2MASS and Gaia second data release (DR2) photometry. The new findings are old and metal-poor GCs located less than 4 kpc from the Galactic center. Camargo 1102 seems to be located over the Galactic bar on the far side of the Milky Way and at a vertical distance lower than 1 kpc. The other four clusters lie even closer to the Milky Way mid-plane. The old ages and low metallicities suggest that the newly discovered GCs may have the potential of providing important clues on the early inner Galaxy formation and its subsequent evolution, as well as the current bulge structure and kinematics.
