In search of the spacetime torsion
(2007-01-01)
Whether torsion plays or not a role in the description of the gravitational interaction is a problem that can only be solved by experiment. This is, however, a difficult task: since there are different possible interpretations ...
Las ondas gravitatorias en la teoría de la relatividad
(Universidad Nacional de Trujillo, 2017)
Results from the Atacama B-mode Search (ABS) experiment
(Institute of Physics Publishing, 2018)
The Atacama B-mode Search is an experiment designed to measure the cosmic
microwave background polarization at large angular scales (` > 40). It observes at 145 GHz
from a site at 5,190 m elevation in northern Chile. The ...
QUBIC VIII: Optical design and performance
(IOP Publishing, 2021-10)
The Q and U Bolometric Interferometer for Cosmology (QUBIC) is a ground-based experiment that aims to detect B-mode polarization anisotropies [1] in the CMB at angular scales around the â.,"≃100 recombination peak. Systematic ...
Estudio post-newtoniano de las ondas gravitacionales en una teoría de gravedad modificada de cuarto orden
(Bogotá - Ciencias - Maestría en Ciencias - AstronomíaUniversidad Nacional de Colombia - Sede Bogotá, 2020-08-18)
Fourth Order gravity theory, discussed by S. Banerjee, S. Vera and T. Singh (2017), is the gravity theory presented in this work. This model is applied to the problem example of the gravitational waves produced by a binary ...
Secondary waves in Ribbing Instability
(American Institute of Physics, 2007-06)
Many natural and technological processes involve phenomena dominated by interfacial mechanics, i.e., occurring within regions of intersection between several fluid and/or solid phases. In addition to capillary and gravitational ...
QUBIC I: Overview and Science Program
(IOP Publishing, 2021-10)
The Q & U Bolometric Interferometer for Cosmology (QUBIC) is a novel kind of polarimeter optimized for the measurement of the B-mode polarization of the Cosmic Microwave Background (CMB), which is one of the major challenges ...
Improved Upper Limits on the Stochastic Gravitational-Wave Background from 2009-2010 LIGO and Virgo Data
(Amer Physical Soc, 2014-12-02)
Gravitational waves from a variety of sources are predicted to superpose to create a stochastic background. This background is expected to contain unique information from throughout the history of the Universe that is ...

QUBIC: The Q & U Bolometric Interferometer for Cosmology
(Springer/Plenum Publishers, 2020-02)
The Q & U Bolometric Interferometer for Cosmology, QUBIC, is an innovative experiment designed to measure the polarization of the cosmic microwave background and in particular the signature left therein by the inflationary ...
