Abstract

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.
