High energy gamma-ray sources in the VVV survey – III. Spectroscopic confirmation of an AGN at low Galactic latitudes
2025
ABSTRACT We aim to spectroscopically confirm the nature of VVV-J181258.71-314346.7, a candidate counterpart to the unassociated gamma-ray source 4FGLJ1812.8−3144. This object was selected based on its near-infrared photometric properties and moderate variability, as part of a broader effort to identify active galactic nuclei (AGNs) behind the Galactic Bulge and Disc. We obtained near-infrared spectra using the Flamingos-2 instrument at Gemini South, covering the 1.1–$1.8~\mu$m range with a spectral resolution of $…
