SUMMARY:The Discovery of Fermi Bubbles and Future Gamma-ray Telescopes
 \, NPAC (Nuclear/Particle/Astro/Cosmo) Forum\, Meng Su\, MIT\, Joint M
 IT Pappalardo and NASA Einstein Fellow
DESCRIPTION:The Fermi Bubbles are a pair of giant lobes at the heart o
 f the Milky Way\, extending roughly 50 degrees north and south of the 
 Galactic Center\, and emitting photons with energies up to 100 GeV. Th
 is previously unknown structure could be evidence for past activity of
  the central supermassive black hole. I will first summarize what we h
 ave learned about the bubbles through multi-wavelength observations an
 d numerical simulations. We discovered the bubbles while searching for
  potential signal of dark matter particle annihilation toward the Gala
 ctic Center\, using data from the Fermi Gamma-ray Space Telescope. Mor
 e than six years successful operation of Fermi has proved the great po
 tential of studying astrophysics\, cosmology\, and fundamental physics
  through gamma-ray sky. I will highlight the search of dark matter par
 ticles using gamma-ray and cosmic-ray observations\, which motivated t
 hree future space telescopes: DAMPE\, HERD\, and PANGU. Together with 
 the next generation ground-based Cherenkov telescopes e.g. CTA and LHA
 ASO\, we will be able to measure gamma-ray photons with energies from 
 MeV to above PeV with much improved sensitivity. Finally\, I will comm
 ent on a future plan to search for primordial gravitational waves prod
 uced from inflation in the very beginning of the Universe.
