Post-Newtonian multipoles from the next-to-leading post-Minkowskian gravitational waveform
(American Physical Society (APS), 2024-05-20)We consider the frequency-domain leading order and next-to-leading order post-Minkowskian waveforms obtained from the tree-level and one-loop amplitudes describing the scattering of two massive scalar objects and the ... -
Design of an Ion-acoustic Proof-of-principle experiment for LhARA

The effect of variations in the magnetic field direction from turbulence on kinetic-scale instabilities
(The European Southern Observatory, 2023)At kinetic scales in the solar wind, instabilities transfer energy from particles to fluctuations in the electromagnetic fields while restoring plasma conditions towards thermodynamic equilibrium. We investigate the interplay ... -
Parker Solar Probe Observations of High Plasma <i>β</i> Solar Wind from the Streamer Belt
(IOP Publishing Ltd, 2023)In general, slow solar wind from the streamer belt forms a high plasma β equatorial plasma sheet around the heliospheric current sheet (HCS) crossing, namely, the heliospheric plasma sheet (HPS). Current Parker Solar Probe ... -

Parker Solar Probe: Four Years of Discoveries at Solar Cycle Minimum
(Springer Nature, 2023)Launched on 12 Aug. 2018, NASA’s Parker Solar Probe had completed 13 of its scheduled 24 orbits around the Sun by Nov. 2022. The mission’s primary science goal is to determine the structure and dynamics of the Sun’s coronal ... -
Conditions for Proton Temperature Anisotropy to Drive Instabilities in the Solar Wind
(IOP Publishing Ltd, 2022)Using high-resolution data from Solar Orbiter, we investigate the plasma conditions necessary for the proton temperature-anisotropy-driven mirror-mode and oblique firehose instabilities to occur in the solar wind. We find ... -
Revolutionizing Our Understanding of Particle Energization in Space Plasmas Using On-Board Wave-Particle Correlator Instrumentation
(Frontiers, 2022)A leap forward in our understanding of particle energization in plasmas throughout the heliosphere is essential to answer longstanding questions in heliophysics, including the heating of the solar corona, acceleration of ... -
The Evolution of the 1/<i>f</i> Range within a Single Fast-solar-wind Stream between 17.4 and 45.7 Solar Radii
(IOP Publishing, 2023)The power spectrum of magnetic field fluctuations in the fast solar wind (VSW > 500 km s−1) at magnetohydrodynamic scales is characterized by two different power laws on either side of a break frequency fb. The low-frequency ... -
The Structure and Origin of Switchbacks: Parker Solar Probe Observations
(IOP Publishing, 2023)Switchbacks are rapid magnetic field reversals that last from seconds to hours. Current Parker Solar Probe (PSP) observations pose many open questions in regard to the nature of switchbacks. For example, are they stable ... -
Mediation of collisionless turbulent dissipation through cyclotron resonance.
(Nature Research, 2024)The dissipation of turbulence in astrophysical systems is fundamental to energy transfer and heating in environments ranging from the solar wind and corona to accretion disks and the intracluster medium. Although turbulent ... -
Turbulence Properties of Interplanetary Coronal Mass Ejections in the Inner Heliosphere: Dependence on Proton Beta and Flux Rope Structure
(IOP Publishing, 2023-10-01)Interplanetary coronal mass ejections (ICMEs) have low proton beta across a broad range of heliocentric distances and a magnetic flux rope structure at large scales, making them a unique environment for studying solar wind ... -
Hubble diagrams in statistically homogeneous, anisotropic universes
(IOP Publishing, 2024-05-29)We consider the form of Hubble diagrams that would be constructed by observers in universes that are homogeneous but anisotropic, when averaged over suitably large length-scales. This is achieved by ray-tracing in different ... -
Test of CP-invariance of the Higgs boson in vector-boson fusion production and in its decay into four leptons
(Springer Nature, 2024-05-09)A search for CP violation in the decay kinematics and vector-boson fusion production of the Higgs boson is performed in the H → ZZ* → 4ℓ (ℓ = e, μ) decay channel. The results are based on proton-proton collision data ... -
Electron and photon efficiencies in LHC Run 2 with the ATLAS experiment
(Springer Nature, 2024-05-14)Precision measurements of electron reconstruction, identification, and isolation efficiencies and photon identification efficiencies are presented. They use the full Run 2 data sample collected by the ATLAS experiment in ... -
Measurement of t-channel single-top-quark production in pp collisions at s=5.02 TeV with the ATLAS detector
(2024-07-01)The observation of the electroweak production of single-top-quarks is made using 255 pb−1 of proton-proton collision data recorded at s=5.02 TeV with the ATLAS detector at the Large Hadron Collider. An event selection is ... -
