Jets are one of the most mysterious, and fascinating subjects in the study of relativistic outflow of the high energy particles produced by the Active Galactic Nuclei (AGN). AGNs are the center of active galaxies, where a very massive black hole is actively accreting matter into it. The relationship between the black hole mass and the luminosity is produced through accretion is known as the fundamental plane of black hole activities. The goal is to probe the characteristics of the black hole and its close vicinity by studying the X-ray produced by this inner region. We report the finding of high energy X-ray photons of a low radio luminous galaxy Mrk 110 from NuSTAR observations. We've found there are almost no variations in the X-ray flux during time scale observation, and there is a linear correlation between 3-5 keV and 5-10 keV energy band. We also find that the energy spectrum is best modeled by a cutoff power law and a red-shifted Gaussian modeling the fluorescence emission. Fluorescence emission is one of the signatures when X-rays are reflected by the disk. However the other significant reflection component, --X-rays signals reflected by the disk, is missing. We suspect the cause of the unexpected amount of high energy X-ray flux is due to jet emissions.
