Genetic algorithm for multi-gravity assist interplanetary trajectory optimisation
(Universitat Politècnica de Catalunya, 2023-02-15)
Projecte Final de Màster Oficial
Accés obertThis master thesis presents the development of a genetic algorithm for optimizing multiplanetary gravity assist trajectories. The algorithm was designed to address the challenges of finding the most efficient trajectory ... -
Gravitational particle production in bouncing cosmologies
(2015-10-13)
Article
Accés obert© 2015 IOP Publishing Ltd and Sissa Medialab srl . It is argued that the Universe reheating in bouncing cosmologies could be explained via gravitational particle production, as due to a sudden phase transition in the ... -
Homothetic motions and Newtonian cosmology
(2014-05-07)
Article
Accés restringit per política de l'editorialWe construct a homothetic covariant Newtonian gravitation theory which unifies inertial homothetic forces and gravitational fields. This is achieved through an equivalence principle based on a local homothetic frame of ... -
On the meaning of Painlevé–Gullstrand synchronization
(2015-11-19)
Article
Accés obertFollowing on from two recent papers, here we examine the relationship between Newtonian gravitation and general relativity in more depth. This allows us to define a scalar potential which is just the proper time of the ... -
On the quantum corrected gravitational collapse
(Elsevier, 2015-06-09)
Article
Accés obertBased on a previously found general class of quantum improved exact solutions composed of non-interacting (dust) particles, we model the gravitational collapse of stars. As the modeled star collapses a closed apparent ... -
Oxygen neutronization in accreting white dwarfs
(1983)
Article
Accés obertSolid carbon-oxygen white dwarf cores have been shown to be likely initial configurations for collapse to neutron star densities. Solidification seems to entail carbon/oxygen separation, with oxygen settling at the star's ... -

Rigid covariance as a natural extension of Painleve-Gullstrand space-times: gravitational waves
(2017-08-01)
Article
Accés obertThe group of rigid motions is considered to guide the search for a natural system of space-time coordinates in General Relativity. This search leads us to a natural extension of the space-times that support Painlevé–Gullstrand ... -
Sensor noise in LISA Pathfinder: in-flight performance of the optical test mass readout
(American Institute of Physics (AIP), 2021-04-02)
Article
Accés obertWe report on the first subpicometer interferometer flown in space. It was part of ESA’s Laser Interferometer Space Antenna (LISA) Pathfinder mission and performed the fundamental measurement of the positional and angular ...
