Anomalous X-ray Pulsars (AXPs) are bright X-ray sources. Few AXPs emit highly
pulsed emission in hard X-rays. Using data collected with the Large Area
Telescope on board Fermi Gamma-ray Space Telescope, we explored high-energy
gamma-ray emission from the brightest AXP, 4U 0142+61. We do not detect any
significant emission from the source. Here, we present the upper limits to the
persistent and pulsed emission of 4U 0142+61 in the high-energy gamma-ray
domain.
