Plasmoid Instability in the Multiphase Interstellar Medium
The Astrophysical Journal Letters, 2023 The processes controlling the complex clump structure, phase distribution, and magnetic field geometry that develop across a broad range of scales in the turbulent interstellar medium (ISM) remain unclear.

Event Rate of Fast Radio Bursts from Binary Neutron Star Mergers
The Astrophysical Journal, 2023 It is proposed that a one-off fast radio burst (FRB) with periodic structure may be produced during the inspiral phase of a binary neutron star (BNS) merger. In this paper, we study the event rate of such kind of FRB.

Magnetic Helicity Fluxes from Triple Correlators
The Astrophysical Journal, 2023 Fluxes of the magnetic helicity density play an important role in large-scale turbulent dynamos, allowing the growth of large-scale magnetic fields while overcoming catastrophic quenching.

Magnetic fields in irregular galaxies [PDF]
Proceedings of the International Astronomical Union, 2008 AbstractThe low masses of irregular galaxies change the behavior of their interstellar medium (ISM) compared to that of normal spirals, so the role of magnetic fields in the ISM in irregulars may be very different than in spirals. We present high-resolution and high-sensitivity observations of the magnetic fields of two irregular galaxies: NGC 4214 and

SIMULATING MAGNETIC FIELDS IN THE ANTENNAE GALAXIES [PDF]
The Astrophysical Journal, 2010 We present self-consistent high-resolution simulations of NGC4038/4039 (the "Antennae galaxies") including star formation, supernova feedback and magnetic fields performed with the N-body/SPH code Gadget, in which magnetohydrodynamics are followed with the SPH method. We vary the initial magnetic field in the progenitor disks from 1 nG to 100 muG.

Magnetic fields and UHECR propagation [PDF]
EPJ Web of Conferences, 2023 I review the main observational tools used to detect and measure magnetic fields in the interstellar medium of our Galaxy (considering both the Galactic disk and the Galactic halo), in the interstellar medium of external galaxies, and in the ...

Magnetic fields in barred galaxies [PDF]
Astronomy & Astrophysics, 2002 The total and polarized radio continuum emission of 20 barred galaxies was observed with the Very Large Array (VLA) at 3, 6, 18 and 22 cm and with the Australia Telescope Compact Array (ATCA) at 6 cm and 13 cm. Maps at 30 arcsec angular resolution are presented here.

Magnetic Fields in Galaxies [PDF]
, 2013 Most of the visible matter in the Universe is ionized, so that cosmic magnetic fields are quite easy to generate and due to the lack of magnetic monopoles hard to destroy. Magnetic fields have been measured in or around practically all celestial objects, either by in-situ measurements of spacecrafts or by the electromagnetic radiation of embedded ...

Origin of magnetic fields in galaxies [PDF]
Physical Review D, 2010 Microgauss magnetic fields are observed in all galaxies at low and high redshifts. The origin of these intense magnetic fields is a challenging question in astrophysics. We show here that the natural plasma fluctuations in the primordial universe (assumed to be random), predicted by the Fluctuation-Dissipation-Theorem, predicts $\sim 0.034 G$ fields ...
