Multichannel highly sensitive diamond quantum magnetometer
We demonstrate a highly sensitive real-time magnetometry method at two measurement points. This magnetometry method is based on the frequency-division multiplexing of continuous-wave optically detected magnetic resonance. We use two ensembles of nitrogen-vacancy (NV) centers separated by 3.6 mm to measure a magnetic field. A different bias field is applied to the two NV ensembles to resolve the resonance peak for each ensemble in the frequency space and enables the multiplexed magnetometry at t…

Jet-driven explosion of an accretion-induced white-dwarf collapse via a magnetorotational dynamo
The accretion-induced collapse (AIC) of a rotating white dwarf (WD) offers a potential site of millisecond pulsars/magnetars, gamma-ray bursts, and r-process nucleosynthesis. We present three-dimensional general-relativistic magneto-hydrodynamical simulations including neutrinos of magnetorotational AIC, assuming the WD is rapidly spinning with a weak magnetic field confined below its surface (likely a prerequisite for rapid rotation). Within milliseconds after core bounce, the magnetic field i…

Variations of the vector magnetic structures in the solar polar regions observed by Hinode
Using the polar vector magnetic field data observed by Hinode from 2012 to 2021, we study the long-term variations of the magnetic flux, the flux proportion of different polarities, and the magnetic inclination with respect to the local normal in the solar polar regions above 70 degree latitude during solar cycle 24. In both polar regions after the polarity reversal, the unsigned magnetic fluxes of the dominant polarity increased to a peak of about 1.3$\times$10$^{22}$ Mx during the solar minim…

Gravitational waves from magnetorotational core-collapse supernovae using 3D GRMHD simulations: effect of rotation and magnetic fields
We investigate the gravitational wave emission for 10 supernova progenitors from magnetorotational core-collapse to the supernova explosion using fully three-dimensional dynamical-spacetime general-relativistic magnetohydrodynamics simulations with the GPU-accelerated code $\texttt{GRaM-X}$. We consider 2 progenitors of zero-age-main-sequence mass $25M_\odot$ and 8 with zero-age-main-sequence masses of $35M_\odot$. For these models, we explore a range of rotation rates between $0.0$ and $3.5 \m…

Residual energy of magnetohydrodynamic shocks
Residual energy quantifies the difference in energy between velocity and magnetic field fluctuations in a plasma. Recent observational evidence highlights that fast-mode interplanetary shock waves have positive residual energy, in sharp contrast to the negative residual energy of the turbulence and magnetic structures that constitute the vast majority of fluctuation power in the solar wind at magnetohydrodynamic (MHD) inertial scales. In this work, we apply the Rankine-Hugoniot conditions to de…
