Traces of Extra Dimensions in Cosmology [PDF]

, 2010
In this thesis, we discuss the observational consequences of extra dimensions on cosmological phenomena. We begin with an overview of extra dimensions, from the initial ideas of Kaluza and Klein to the more recent concept of braneworld models and in ...

Alternative Approach to Tilt-to-Length Coupling Estimation for Laser Ranging Interferometers in Future Gravity Missions

Remote Sensing
Tilt-to-length coupling, a non-constant systematic error source caused by satellite attitude variations, has been observed in the laser ranging signals of the GRACE Follow-On mission. This error can be corrected by certain calibration maneuvers performed

Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis can influence magmatism and deformation beyond the rift zone.

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

Equiaffine Braneworld

Galaxies, 2020
Higher dimensional theories, wherein our four dimensional universe is immersed into a bulk ambient, have received much attention recently, and the directions of investigation had, as far as we can discern, all followed the ordinary Euclidean hypersurface

Lunar Crustal Formation by Melt Migration and Differentiation Within a Stagnant Lid

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The lunar anorthosite highlands represent the Moon's primary crust, which formed during the solidification of a magma ocean following the Moon‐forming giant impact. However, the canonical model of anorthite flotation in the crystallizing magma ocean often struggles to reproduce the long > ${ >} $200 Myr solidification timescale required by the

Normalizing flows as an avenue to study overlapping gravitational wave signals

, 2022
Due to its speed after training, machine learning is often envisaged as a solution to a manifold of the issues faced in gravitational-wave astronomy. Demonstrations have been given for various applications in gravitational-wave data analysis.

Characterization of Dust in Saturn's Rings Using Cassini Spacecraft Data

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract The dust distribution in Saturn's rings is investigated using dust impacts registered by the Radio and Plasma Wave Science (RPWS) instrument onboard the Cassini spacecraft. Dust impacts, recorded as spiky signals in electric field waveforms, are used to determine profiles of impact rates and amplitudes of spikes during individual equatorial ...
