MAGNETIC FIELDS IN CLUSTERS OF GALAXIES [PDF]
International Journal of Modern Physics D, 2004 The existence of magnetic fields associated with the intracluster medium in clusters of galaxies is now well established through different methods of analysis. Magnetic fields are investigated in the radio band from studies of the rotation measure of polarized radio galaxies and the synchrotron emission of cluster-wide diffuse sources.

Magnetic fields in galaxies [PDF]
Proceedings of the International Astronomical Union, 2005 AbstractThe origin and evolution of magnetic fields in the Universe is a cosmological problem. Although exotic mechanisms for magneotgenesis cannot be ruled out, galactic magnetic fields could have been seeded by magnetic fields from stars and accretion disks, and must be continuously regenerated due to the ongoing replacement of the interstellar ...

The Magnetic Field in Edge-On Galaxies [PDF]
Symposium - International Astronomical Union, 1990 We observed the linearly polarized emission of the edge-on galaxies NGC891 and NGC4631 in order to determine the magnetic field structure.

From Flow to Function: Using Different Static Mixers to Fabricate Microarchitected Materials Via Chaotic Printing. [PDF]
Adv Sci (Weinh)Complex microarchitectures emerge from simple flow‐driven transformations as static mixers iteratively reorient and split material domains. Coupled with diverse deposition strategies, chaotic printing provides an accessible platform for fabricating architected materials that support biologically and chemically relevant processes.

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 in spiral galaxies [PDF]
The Astronomy and Astrophysics Review, 1990 Radio synchrotron emission is a powerful tool to study the strength and structure of magnetic fields in galaxies. Unpolarized synchrotron emission traces isotropic turbulent fields which are strongest in spiral arms and bars (20-30 μG) and in central starburst regions (50-100 μG).

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 ...

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.
