Query: Are GeV and TeV spectra connected? the case of Galactic gamma-ray
  sources   To understand Galactic objects that emits GeV-TeV emission, a spatial
correlation study between the Fermi bright source catalog and TeV source
population was carried out in Tam et al. (2010), finding that a significant
number of very high-energy (VHE; E >100 GeV) sources are also emitting at GeV
energies. We extended our previous study utilizing the first Fermi catalog
(1FGL) sources. A cross-correlation comparison of the 1FGL sources was carried
out with the VHE gamma-ray sources in the literature as of May 2011. While it
is found that a significant number of VHE gamma-ray sources were also detected
in the GeV band, the GeV-TeV spectra of some of these spatially coincident
sources cannot be described by a single spectral component. While some of these
cases are gamma-ray pulsars accompanied by VHE gamma-ray emitting nebulae, we
present cases where the 100 MeV to multi-TeV spectra of coincident 1FGL/VHE
source pairs do not seem to be well fit by a single spectral component.
