Implementation of frequency-correlated noise in CMB component separation: Method, Validation, and Early Applications
L. Zapelli, M. Bersanelli, L. P. L. Colombo +24
Parametric component separation methods used in cosmic microwave background (CMB) analyses commonly assume instrumental noise to be uncorrelated between frequency channels. This ap…
Hydrodynamic models of reheating
Juan Pablo Elía, Lucas Cantarutti, Nahuel Mirón-Granese +1
We develop a causal hydrodynamic model that provides an effective macroscopic description of the field-theoretic dynamics during the early stages of reheating. The inflaton condens…
Bias in the tensor-to-scalar ratio from self-interacting dark radiation
Nahuel Mirón-Granese, Claudia G. Scóccola
We investigate the cosmological imprint of self-interacting dark radiation (DR) on the primordial -mode angular power spectrum and its impact on the estimation of the tensor-to-…
O-covariant formulation of perfect and imperfect fluids in the double geometry
Eric Lescano, Nahuel Mirón-Granese, Yuho Sakatani
We study generic matter coupled to a -dimensional supergravity using a formulation of Double Field Theory (DFT), where all the fields are encoded in O multiplets. We stud…
Measuring the CMB primordial B-modes with Bolometric Interferometry
A. Mennella, P. Ade, A. Almela +111
The Q&U Bolometric Interferometer for Cosmology (QUBIC) is the first bolometric interferometer designed to measure the primordial B-mode polarization of the Cosmic Microwave Backgr…
Double Field Theory with matter and the generalized Bergshoeff-de Roo identification
Eric Lescano, Nahuel Mirón-Granese
The scalar field-perfect fluid (sf-pf) correspondence shows that the energy-momentum tensor of a scalar field is in correspondence with the dynamics of a perfect fluid. In this wor…
Double Field Theory with matter and its cosmological application
Eric Lescano, Nahuel Mirón-Granese
The phase space formulation of Double Field Theory (DFT) indicates that statistical matter can be included in terms of (T-)duality multiplets. We propose the inclusion of a perfect…
Primordial Weibel instability
Nahuel Mirón-Granese, Esteban Calzetta, Alejandra Kandus
We study the onset of vector instabilities in the post-inflationary epoch of the Universe as a mechanism for primordial magnetic fields amplification. We assume the presence of a c…
Nonlinear Dynamics of Tensor Modes in Conformal Real Relativistic Fluids
Nahuel Mirón-Granese, Esteban Calzetta, Alejandra Kandus
In the Second Order Theories (SOT) of real relativistic fluids, the non-ideal properties are described by a new set of dynamical tensor variables. In this work we explore the non-l…
