Abstract
MGRO J2019+37 within the Cygnus region is a bright and extended source revealed by Milagro at 12-35 TeV. This source is almost as bright as Crab Nebula in northern sky, while it is not confirmed by ARGO-YBJ around TeV. Up to now, no obvious counterpart at low energy wavelengths has been found. Hence, MGRO J2019+37 becomes mysterious and its VHE gamma-ray emission mechanism is attractive. In this paper, a brief summary of the multi-wavelength observations from Radio to gamma-ray is presented. All the available data from the XMM-Newton and INTEGRAL at X-ray, and the Fermi-LAT at gamma-ray bands were used to get constraint on its emission flux at low energy wavelengths. Then, its possible counterparts and the VHE emission mechanism are discussed.
