No conformal anomaly in unimodular gravity [PDF]
Physical Review D, 2013 The conformal invariance of unimodular gravity survives quantum corrections, even in the presence of conformal matter. Unimodular gravity can actually be understood as a certain truncation of the full Einstein-Hilbert theory, where in the Einstein frame the metric tensor enjoys unit determinant.

The planning of the first and second order relative gravimetric networks for the territory of the Republic of Albania [PDF]
Micro, Macro & Mezzo Geoinformation, 2020 This paper presents the first and second order gravimetric relative network planning for the territory of the Republic of Albania, as well as the calculation of free-air anomalies, Bouguer anomalies, and Bouguer gravity.

Application of Radial Basis Functions for Height Datum Unification
Geosciences, 2018 Local gravity field modelling demands high-quality gravity data as well as an appropriate mathematical model. Particularly in coastal areas, there may be different types of gravity observations available, for instance, terrestrial, aerial, marine gravity,

Anomalies in covariant W-gravity
Physics Letters B, 1991 Abstract We consider free scalar matter covariantly coupled to background W-gravity. Expanding to second order in the W-gravity fields, we study the appropriate anomalous Ward-Takahashi identities and find the counterterms which maintain diffeomorphism invariance and its W-analogue. We see that a redefinition of the vielbein transformation rule under

SPACETIME OR QUANTUM PARTICLES: THE ONTOLOGY OF QUANTUM GRAVITY? [PDF]
, 1996 The domains of quantum theory and general relativity overlap in situations where quantum mechanical effects cannot be ignored. In order to deal with this overlap of theoretical domains, there has been a tendency to apply the rules of quantum field theory

Gravity Anomalies in the Galpagos Islands Area [PDF]
Science, 1974 In a recent report Case et al. (1) presented a free-air gravity anomaly map of the Galapagos Islands based on 32 gravity stations on the islands. On the basis of their data they stated that the Galapagos Islands are associated with an east-west trending "residual negative anomaly" which is superimposed on a "broader positive anomaly of unknown ...

Gravity analyses for the crustal structure and subglacial geology of West Antarctica, particularly beneath Thwaites Glacier [PDF]
, 2008 textThe West Antarctic Ice Sheet (WAIS) is mostly grounded in broad, deep basins (down to 2.5 km below sea level) that are stretched between five crustal blocks. The geometry of the bedrock, being mostly below sea level, induces a fundamental instability

Inland extent of the Weddell Sea Rift imaged by new aerogeophysical data [PDF]
, 2013 The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica from a collage of crustal blocks in West Antarctica.
