Noble gases and nitrogen in material from asteroid Bennu
Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1593-1609, July 2026.Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.

Magnetic Fields in Irregular Galaxies [PDF]
, 2008 Magnetic fields are an important component of the interstellar medium, especially in low-mass galaxies like irregulars where the magnetic pressure may be significant. However, few irregular galaxies have observed magnetic field structures. Using the VLA, the GBT, and the ATCA, we have observed several irregular galaxies in the radio continuum to ...

MHD numerical simulations in a cosmological context [PDF]
, 2011 Magnetic fields in the Universe are found in almost all studied environments. In particular, their presence in the inter-galactic medium and in the intra-cluster medium is confirmed by diffuse radio emission as well as by observations of Faraday ...

Magnetic fields in clusters of galaxies [PDF]
, 2018 Magnetic fields in clusters of galaxies play a critical role in shaping up the intracluster medium. Their existence has been established through observations of synchrotron emission, especially from radio relics and halos, as well as observations of ...

Multiscale magnetic fields in spiral galaxies: evolution and reversals [PDF]
, 2012 Context. Magnetic fields in nearby, star-forming galaxies reveal large-scale patterns, as predicted by dynamo models, but also a variety of small-scale structures. In particular, a large-scale field reversal may exist in the Milky Way

Environment matters: stronger magnetic fields in satellite galaxies [PDF]
Magnetic fields are ubiquitous in the universe and an important component of the interstellar medium. It is crucial to accurately model and understand their properties in different environments and across all mass ranges of galaxies to interpret ...

Magnetic Fields in Clusters of Galaxies [PDF]
, 2003 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. Other techniques

Magnetic Fields in Nearby Galaxies [PDF]
Observations of synchrotron radiation and the Faraday rotation of its polarized component allow us to investigate the magnetic properties of the diffuse interstellar medium in nearby galaxies, on scales down to roughly one hundred parsecs.

Magnetic fields in barred galaxies [PDF]
, 2005 We present $\lambda3.5$ cm and $\lambda6.2$ cm radio continuum maps in total and polarized intensity of the barred galaxies NGC 1097 (at 2´´–15´´ resolution) and NGC 1365 (at 9´´–25´´ resolution).
