Validation of Recent DSM/DEM/DBMs in Test Areas in Greece Using Spirit Leveling, GNSS, Gravity and Echo Sounding Measurements

open access: yesISPRS International Journal of Geo-Information, 2023
Recent Digital Surface, Elevation, and Bathymetric Models (DSM/DEM/DBM) aim to provide high-resolution and accurate height and depth information needed for a variety of surveying, geodetic, geophysical, and other applications. In this study, first we aim

Integration of Residual Terrain Modelling and the Equivalent Source Layer Method in Gravity Field Synthesis for Airborne Gravity Gradiometer Test Site Determination

open access: yesRemote Sensing, 2023
To calibrate airborne gravity gradiometers currently in development in China, it is urgent to build an airborne gravity gradiometer test site. The site’s selection depends on the preknowledge of high-resolution gravity and gradient structures.

Characterization of Icy Moon Hydrospheres Through Joint Inversion of Gravity and Magnetic Field Measurements

open access: yesGeophysical Research Letters, 2023
Several bodies in the outer solar system are believed to host liquid water oceans underneath their icy surfaces. Knowledge of the hydrosphere properties is essential for understanding and assessing their habitability.

The relationship of the oil and gas fields of the Forecarpathian region with the regional faults system and deep structure

open access: yesГеофизический журнал, 2022
The oil and gas fields of Forecarpathian oil and gas region are compared with the structure of earth’s crust and regional faults. Most of the oil and gas condensate fields are localized in Borislav-Pokutia nappe over Precarpathian Fault zone.

Bosons Thermodynamics in the gravity field

open access: yes, 2023
Abstract A uniform force like the weight has been shown to forbid Bose-Einstein condensation (BEC), due to the discretness of the Airy spectrum, resulting from the weight. We show that BEC is forbidden even if the Airy spectrum is treated as continuous, in what we call the approximate continuous limit (ACL). The absence of BEC is due to the non

Quantum Gravity: Motivations and Alternatives [PDF]

open access: yes, 2009
The mutual conceptual incompatibility between General Relativity and Quantum Mechanics / Quantum Field Theory is generally seen as the most essential motivation for the development of a theory of Quantum Gravity.

GRACE—Gravity Data for Understanding the Deep Earth’s Interior

open access: yesRemote Sensing, 2020
While the main causes of the temporal gravity variations observed by the Gravity Recovery and Climate Experiment (GRACE) space mission result from water mass redistributions occurring at the surface of the Earth in response to climatic and anthropogenic ...

Gravitational instability of exotic compact objects

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Exotic compact objects with physical surfaces a Planckian distance away from where the horizon would have been are inspired by quantum gravity. Most of these objects are defined by a classical spacetime metric, such as boson stars, gravastars and ...
