Unravelling unidentified γ-ray sources with the large millimeter telescopeA meV look to the high energy sky

The understanding of the high energy γ-ray sky requires a coordinated multi-wavelength strategy. The Large Millimeter Telescope will be the largest and most sensitive single dish antenna operating between 0.8 mm and 3 mm in the foreseeable future. Its first light instrumentation and capabilities are well suited for studies of dust, dense molecular gas and the synchrotron emission from relativistic electrons. The Large Millimeter Telescope, due to enter commissioning and first light science phase in 2007, will be able to complement GLAST observations and help disentangling the nature of the new and old unidentified gamma-ray sources.
