A new approach and code for spinning black holes in modified gravity
(IOP Publishing Ltd, 2023)We discuss and implement a spectral method approach to computing stationary and axisymmetric black hole solutions and their properties in modified theories of gravity. The resulting code is written in the Julia language ... -
Multi-field inflation with large scalar fluctuations: non-Gaussianity and perturbativity
(IOP Publishing, 2023-09-01)Recently multi-field inflation models that can produce large scalar fluctuations on small scales have drawn a lot of attention, primarily because they could lead to primordial black hole production and generation of large ... -
Buoyancy response of a disc to an embedded planet: a cross-code comparison at high resolution
(Oxford University Press (OUP), 2023-09-11)In radiatively inefficient, laminar protoplanetary discs, embedded planets can excite a buoyancy response as gas gets deflected vertically near the planet. This results in vertical oscillations that drive a vortensity ... -
Solar wind parameters influencing magnetosheath jet formation: low and high IMF cone angle regimes
(American Geophysical Union, 2023)Magnetosheath jets are localized flows of enhanced dynamic pressure that are frequently observed downstream of the Earth's bow shock. They are significantly more likely to occur downstream of the quasi-parallel shock than ... -
Shocklets and Short Large Amplitude Magnetic Structures (SLAMS) in the high Mach foreshock of Venus
(Wiley Open Access, 2023)Shocklets and short large-amplitude magnetic structures (SLAMS) are steepened magnetic fluctuations commonly found in Earth's upstream foreshock. Here we present Venus Express observations from the 26th of February 2009 ... -
Self-consistent modeling of the energetic storm particle event of 10 November 2012
(EDP Sciences, 2023)Context. It is thought that solar energetic ions associated with coronal and interplanetary shock waves are accelerated to high energies by the diffusive shock acceleration mechanism. For this mechanism to be efficient, ... -
The observed number counts in luminosity distance space
(2023-08-01)Next generation surveys will provide us with an unprecedented number of detections of supernovae Type Ia and gravitational wave merger events. Cross-correlations of such objects offer novel and powerful insights into the ... -
Testing gravitational wave propagation with multiband detections
(2023-03-01)Effective field theories (EFT) of dark energy (DE) — built to parameterise the properties of DE in an agnostic manner — are severely constrained by measurements of the propagation speed of gravitational waves (GW). However, ... -
On the Transmission of Turbulent Structures across the Earth's Bow Shock
(IOP Publishing Ltd, 2022-07)Collisionless shocks and plasma turbulence are crucial ingredients for a broad range of astrophysical systems. The shock–turbulence interaction, and in particular the transmission of fully developed turbulence across the ... -
Annual Variations in the Near-Earth Solar Wind
(Springer, 2023)Earth’s orbit and rotation introduces systematic annual variations in geomagnetic activity, most notably via the changing orientation of the dayside magnetospheric magnetic field with respect to the heliospheric magnetic ... -
Single-spacecraft techniques for shock parameters estimation: A systematic approach

Investigating the Role of Magnetosheath High-Speed Jets in Triggering Dayside Ground Magnetic Ultra-Low Frequency Waves
(Wiley Open Access, 2022-11-28)Ultra-low frequency (ULF) waves significantly contribute to transferring energy and transporting particles in the coupled magnetosphere-ionosphere system. Recent studies suggested magnetosheath high-speed jets (HSJs) can ... -
