    • Tracking Stellar Activity Enhancements Due To A Close-in Giant Planet In The HD 179949 System 

      Gurdemir, Levent (Physics, 2010-07-19)
      We monitored CaII H and K lines (3933Å and 3968Å) of the HD 179949 system to study Planet Induced Emission (PIE) as an effect of star-planet interaction. We obtained high resolution spectra (R > 50,000) with high signal-to-noise ...
    • Two-photon Optogenetic Stimulation Of Cells 

      Dhakal, Kamal Raj (Physics, 12-15-2012)
      The controlled stimulation of cells, especially neurons, is of significant interest both for basic understanding of neuronal circuitry as well as clinical interventions. Existing electrode-based methods of stimulation ...
