Exploring high-frequency gravitational waves with magnons

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
Detecting gravitational waves with frequencies higher than 10 kHz requires new strategies. In previous papers, we proposed magnon gravitational wave detectors and gave the first limit on gigahertz gravitational waves by reinterpreting the existing data ...

Primordial black holes and gravitational waves from parametric amplification of curvature perturbations [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2019
We investigate a new mechanism to create large curvature perturbations on small scales due to parameter resonance in a single-field inflationary model with a small periodic structure upon the potential.

Gravitational waves in the nonsymmetric gravitational theory [PDF]

open access: yesPhysics Letters A, 1993
We prove that the flux of gravitational radiation from an isolated source in the Nonsymmetric Gravitational Theory is identical to that found in Einstein's General Theory of Relativity.

Test gravitational waves in sandwich wave background [PDF]

open access: yes, 2023
The scattering of test fields by sandwich waves has been studied extensively. It has been found that for a variety of test fields, the energy of the scattered waves is amplified. In this paper, Scattering of test gravitational waves by sandwich waves are calculated by solving gravitational perturbations in the sandwich wave background.

All-sky search for continuous gravitational waves from isolated neutron stars using Advanced LIGO O2 data [PDF]

open access: yes, 2019
We present results of an all-sky search for continuous gravitational waves (CWs), which can be produced by fast-spinning neutron stars with an asymmetry around their rotation axis, using data from the second observing run of the Advanced LIGO detectors ...

Probing the theory of gravity with gravitational lensing of gravitational waves and galaxy surveys [PDF]

open access: yesMonthly notices of the Royal Astronomical Society, 2019
The cross-correlation of gravitational wave strain with upcoming galaxy surveys probes theories of gravity in a new way. This method enables testing the theory of gravity by combining the effects from both gravitational lensing of gravitational waves ...

Sediment supply control on morphodynamic processes in gravel‐bed river widenings

open access: yesEarth Surface Processes and Landforms, Volume 47, Issue 15, Page 3415-3434, December 2022., 2022
Mobile‐bed laboratory experiments combined with two‐dimensional hydrodynamic numerical simulations showed that sediment supply is a key driver of morphodynamic activity in reach‐scale dynamic river widenings. Sediment supply roughly balanced with the channel's transport capacity led to active channel widening and continued patchy sediment relocation ...

Stable Droplet Manipulation in Multiple Directions on a Magnetically Responsive Micropillar Array Surface

open access: yesAdvanced Materials Interfaces, EarlyView.
The directional rolling motion of low‐surface‐tension working fluids and water droplets on a superhydrophobic magnetically responsive micropillar array (SMMA) is investigated. The factors influencing these instabilities are studied using data analysis. Techniques for capturing and releasing droplets are investigated, offering significant insights into ...
