Cosmic inflation in modified models of gravity and an analysis on gravitational waves
(2021)
This work comprises three different lines of research related to the study of cosmological inflation and the propagation of gravitational waves. In the first issue, we developed -for the first time in a systematic way- the ...

Vanishing of local non-gaussianity in canonical single field inflation
(IOP Publishing, 2018-05)
We study the production of observable primordial local non-Gaussianity in two opposite regimes of canonical single field inflation: attractor (standard single field slow-roll inflation) and non attractor (ultra slow-roll ...
Doubly Symmetric finite-core Heton Equilibria
(Journal of Fluid Mechanics, 2012-01-01)
A finite-core heton is a baroclinic f -plane modon of a special type: it is composed of two patches of uniform quasi-geostrophic potential vorticity (PV) residing in different layers of a two-layer rotating fluid. This ...
Polarization in Monte Carlo radiative transfer and dust scattering polarization signatures of spiral galaxies
(EDP Sciences, 2017-05)
Polarization is an important tool to further the understanding of interstellar dust and the sources behind it. In this paper we describe
our implementation of polarization that is due to scattering of light by spherical ...
An axisymmetric charged dust distribution with NUT rotation in general relativity
(2010)
An exact solution of the Einstein-Maxwell's field equations is presented. This solution describes an axisymmetric charged dust distribution, with NUT rotation, in the presence of an electromagnetic field of the pure magnetic ...

An exact solution of the Einstein-Maxwell's field equations is presented. This solution describes an axisymmetric charged dust distribution, with NUT rotation, in the presence of an electromagnetic field of the pure magnetic ...
Ensemble Space-Time Correlation of Plasma Turbulence in the Solar Wind
(American Physical Society, 2016-06)
Single point measurement turbulence cannot distinguish variations in space and time. We employ an ensemble of one- and two-point measurements in the solar wind to estimate the space-time correlation function in the comoving ...
Relativistic effects of our galaxy's motion on circles-in-the-sky in CMB maps
(2005-06-07)
For an observer in the Hubble flow, the last scattering surface (LSS) is well approximated by a 2-sphere. If a non-trivial topology of space is detectable, then this sphere intersects some of its topological images, ...
