Gravity anomalies over extinct spreading centres: A new evidence of an aborted ridge in the South Atlantic Ocean
(2019-01-01)
An aborted ridge has been suggested in the Vema region, South Atlantic Ocean, and we investigate it in terms of residual gravity anomalies and half spreading rate. Gravity signature over extinct spreading centres displays ...
VIPIR and 50 MHz radar studies of gravity wave signatures in 150‐km echoes observed at Jicamarca
(American Geophysical Union, 2020-08)
Range‐time‐intensity (RTI) plots of 50 MHz radar backscatter detected at Jicamarca from the 150‐km region of the equatorial ionosphere exhibit necklace‐shaped multilayered structures first reported by Kudeki and Fawcett ...
Gravitational signature of Schwarzschild black holes in dynamical Chern-Simons gravity
(AMER PHYSICAL SOC, 2010)
Dynamical Chern-Simons gravity is an extension of general relativity in which the gravitational field is coupled to a scalar field through a parity-violating Chern-Simons term. In this framework, we study perturbations of ...
