    • Direct search for features in the primordial bispectrum 
      Appleby, Stephen; Gong, Jinn-Ouk; Hazra, Dhiraj Kumar; Shafieloo, Arman; Sypsas, Spyros (Elsevier, 2016)
      We study features in the bispectrum of the primordial curvature perturbation correlated with the reconstructed primordial power spectrum from the observed cosmic microwave background temperature data. We first show how the ...
    • Shapes and features of the primordial dispectrum 
      Gong, Jinn Ouk; Palma Quilodrán, Gonzalo; Sypsas, Spyros (IOP Publishing Ltd., 2017)
      If time-dependent disruptions from slow-roll occur during inflation, the correlation functions of the primordial curvature perturbation should have scale-dependent features, a case which is marginally supported from the ...
