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 by means of a potential independent analysis. We focus our attention on inflationary solutions characterized by a constant or varying sound speed as well as warp factor. We impose bounds on stringy aspects of the model, such as the warp factor (f) and the induced gravity parameter (m̃). We study the parameter space of… 
Mimetic DBI Inflation in Confrontation with Planck2018 Data
We study mimetic gravity in the presence of a Dirac–Born–Infeld (DBI)-like term, which is a non-canonical setup of the scalar field’s derivatives. We consider two general cases with varying and
Brans-Dicke inflation in light of the Planck 2015 data
We study inflation in the Brans-Dicke gravity as a special model of the scalar-tensor gravity. We obtain the inflationary observables containing the scalar spectral index, the tensor-to-scalar ratio,
Consistency relation and non-Gaussianity in a Galileon inflation
We study a particular Galileon inflation in the light of Planck2015 observational data in order to constraint the model parameter space. We study the spectrum of the primordial modes of the density
Galileon Intermediate Inflation
The results show that although the prediction of intermediate inflation in the standard framework is completely ruled out by the Planck 2015 observations, it can be put inside the allowed regions of the Plank 2015 TT,TE,EE+lowP data in the Galileon setting.
Viable intermediate inflation in the mimetic DBI model
We study the intermediate inflation in the mimetic Dirac–Born–Infeld model. By considering the scale factor as $$a=a_{0}\exp (bt^{\beta })$$ a = a 0 exp ( b t β ) , we show
Inflaton candidates: from string theory to particle physics
Cosmic inflation is the cornerstone of modern cosmology. In particular, following the Planck mission reports presented in 2015 regarding cosmic microwave background (CMB), there is an increasing
Tree-level bispectrum in the effective field theory of large-scale structure extended to massive neutrinos
We compute the tree-level bispectrum of dark matter in the presence of massive neutrinos in the mildly non-linear regime in the context of the effective field theory of large-scale structure
Logamediate Inflation in f(T) Teleparallel Gravity
We study logamediate inflation in the context of f(T) teleparallel gravity. f(T)-gravity is a generalization of the teleparallel gravity which is formulated on the Weitzenbock spacetime,
Inflation from string field theory
In the framework of string field theory (SFT) a setting is considered, where the closed string dilaton is coupled to the open string tachyon at the final stage of an unstable brane or
The cosmological analysis of the SDSS/BOSS data from the Effective Field Theory of Large-Scale Structure
The Effective Field Theory of Large-Scale Structure is a formalism that allows us to predict the clustering of Cosmological Large-Scale Structure in the mildly non-linear regime in an accurate and


DBI Galileon in the Effective Field Theory of Inflation: Orthogonal non-Gaussianities and constraints from the Trispectrum
Very few explicit inflationary scenarios are known to generate a large bispectrum of orthogonal shape. Dirac-Born-Infeld Galileon inflation, in which an induced gravity term is added to the DBI
Observational constraints on Tachyon and DBI inflation
We present a systematic method for evaluation of perturbation observables in non-canonical single-field inflation models within the slow-roll approximation, which allied with field redefinitions
Orthogonal non-Gaussianity in DBI galileon: prospect for Planck polarization and post-Planck experiments
In this paper, we study cosmic microwave background (CMB) constraints on primordial non-Gaussianity in Dirac–Born–Infeld (DBI) galileon models in which an induced gravity term is added to the DBI
DBI Galileon inflation in background SUGRA
Detecting primordial B-modes after Planck
We update the forecasts for the measurement of the tensor-to-scalar ratio r for various ground-based experiments (AdvACT, CLASS, Keck/BICEP3, Simons Array, SPT-3G), balloons (EBEX 10k and Spider) and
Primordial fluctuations and non-Gaussianities from multifield DBI Galileon inflation
We study a cosmological scenario in which the DBI action governing the motion of a D3-brane in a higher-dimensional spacetime is supplemented with an induced gravity term. The latter reduces to the
Planck 2015. XX. Constraints on inflation
We analyse the implications of the Planck data for cosmic inflation. The Planck nominal mission temperature anisotropy measurements, combined with the WMAP large-angle polarization, constrain the
Consistency relation in power law G-inflation
In the standard inflationary scenario based on a minimally coupled scalar field, canonical or non-canonical, the subluminal propagation of speed of scalar perturbations ensures the following
Joint analysis of BICEP2/keck array and Planck Data.
Strong evidence for dust and no statistically significant evidence for tensor modes is found and various model variations and extensions are probe, including adding a synchrotron component in combination with lower frequency data, and find that these make little difference to the r constraint.
Phenomenology of D-brane inflation with general speed of sound
A characteristic of D-brane inflation is that fluctuations in the inflaton field can propagate at a speed significantly less than the speed of light. This yields observable effects that are distinct
