    • Landscape tomography through primordial non-Gaussianity 
      Chen, Xingang; Palma, Gonzalo; Riquelme, Walter; Scheihing H., Bruno; Sypsas, Spyros (American Physical Society, 2018)
      In this paper, we show how the structure of the landscape potential of the primordial Universe may be probed through the properties of the primordial density perturbations responsible for the origin of the cosmic microwave ...
    • Scale invariance of the primordial tensor power spectrum 
      Palma Quilodrán, Gonzalo; Pradenas Márquez, Bastián; Riquelme, Walter; Sypsas, Spyros (American Physical Society, 2017)
      Future cosmic microwave background polarization experiments will search for evidence of primordial tensor modes at large angular scales, in the multipole range 4≤≤50. Because in that range there is some mild evidence of ...
