Reappraising elastic thickness variation at oceanic trenches [PDF]

We reassess the variation of elastic thickness as a function of lithospheric plate age using a global database of bathymetric and free-air gravity profiles which are perpendicular to oceanic trenches.

Accurate gravity anomaly interpolation: a case-study in Cameroon, Central Africa

Earth Sciences Research Journal, 2007
Many treatments in geodesy and geophysics require regularly gridded gravity anomalies. The gridding of gravity data needs interpolation. For the predicted data to be accurate, the smoothest type of<br />gravity anomaly should be used along with the

Gravity and Gauge [PDF]

, 2012
Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and (Yang-Mills-type) gauge theories.

Gravity anomalies from airborne measurements - experiments using a low cost IMU device

The gravity field may be determined using different techniques, but airborne gravity surveying is becoming a powerful tool mainly due to its potential in remote areas.

Renormalization group flow of f(R)-gravity [PDF]

, 2008
We use the functional renormalization group equation for quantum gravity to construct a non-perturbative flow equation for modified gravity theories of the form $S = \int d^dx \sqrt{g} f(R)$.

On Gravity Inversion by No-Topography and Rigorous Isostatic Gravity Anomalies

, 2015
We discuss some theoretical aspects and practical consequences of using traditional versus “new”/rigorous formulations of the Bouguer and isostatic gravity anomalies/disturbances.

Bouguer and aeromagnetic anomalies in the Iberian Chain (NE Spain); a qualitative interpretation

Geogaceta
This work shows the Bouguer and aeromagnetic anomaly maps of the Iberian Chain (NE Spain) and surroundings in relation to its main geological and structural units. In general, both gravity and aeromagnetic anomalies are aligned following the same trends

Trace anomaly in metric-affine gravity

Physical Review D
We explore the trace (Weyl) anomaly within a general metric-affine geometry that includes both torsion and nonmetricity. Using the Heat Kernel method and Seeley's algorithm, we compute the Minakshisundaram coefficients for arbitrary spacetimes within this framework, incorporating the effects of the nonmetricity and torsion tensors for the first time ...
