Mascon gravitation model using a shaped polyhedral source
(2015-01-01)
In the last two decades, new computational tools have been developed in order to aid space missions to orbit around irregular small bodies. One of the techniques consists in rebuilding their shape in tetrahedral polyhedron. ...
Gravitational Quasinormal Modes of Regular Phantom Black Hole
(Hindawi Ltd, 2017-01-01)
We investigate the gravitational quasinormal modes (QNMs) for a type of regular black hole (BH) known as phantom BH, which is a static self-gravitating solution of a minimally coupled phantom scalar field with a potential. ...
Mass-dimension-one fermions and their gravitational interaction
(2019-01-01)
We investigate in detail the interaction between the spin-(1/2) field endowed with mass dimension one and the graviton. We obtain an interaction vertex that combines the characteristics of scalar-graviton and Dirac's ...
3D stability orbits close to 433 Eros using an effective polyhedral model method
(Oxford University Press, 2014-03-01)
One of the techniques used in the past decade to determine the shape with a good accuracy and estimate certain physical features (volume, mass, moments of inertia) of asteroids is the polyhedral model method. We rebuild ...
Improving our ability to distinguish gravitational-wave signals from detector transient noise for the fourth LIGO-Virgo-KAGRA observing run
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2023-07-12)
A pesar de haber alcanzado sensibilidades capaces de detectar la amplitud extremadamente pequeña de las ondas gravitacionales (GWs), los datos de los detectores LIGO y Virgo contienen frecuentes ráfagas de ruido transitorio ...

High-altitude resolution stratospheric measurements with the arecibo 430-MHz radar
(American Geophysical Union, 1980-03)
The potential of the Arecibo 430-MHz radar for the study of stratospheric dynamics and turbulence has been recently established. In the past the instrumented resolution of the system has been larger than 300-600 m. The ...
The role of reconnection diffusion in the gravitational collapse of turbulent cloud cores
(International Astronomical UnionFlorianópolis, 2013)
For a molecular cloud clump to form stars some
transport of magnetic flux is required from the
denser, inner regions to the outer regions of the
cloud, otherwise this can prevent the collapse. Fast
magnetic reconnection ...
