Gravitational waves in attractors
K. Sravan Kumar, João Marto, Paulo Vargas Moniz +1
We study inflation in the attractor model under a non-slow-roll dynamics with an ansatz proposed by Gong \& Sasaki \cite{Gong:2015ypa} of assuming . Under th…
Coupled scalar fields in the late Universe: The mechanical approach and the late cosmic acceleration
Alvina Burgazli, Alexander Zhuk, João Morais +2
In this paper, we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, we consider the Universe to be filled with dust-…
Non-slow-roll dynamics in attractors
K. Sravan Kumar, João Marto, Paulo Vargas Moniz +1
In this paper we consider the attractor model and study inflation under a non-slow-roll dynamics. More precisely, we follow the approach recently proposed by Gong and Sasaki \c…
DBI Galileon inflation in the light of Planck 2015
K. Sravan Kumar, Juan C. Bueno Sanchez, Celia Escamilla-Rivera +2
In this work we consider a DBI Galileon (DBIG) inflationary model and constrain its parameter space with the Planck 2015 and BICEP2/Keck array and Planck (BKP) joint analysis data…
