Magnetic fields in barred galaxies [PDF]
Astronomy & Astrophysics, 2001 We study the generation and maintenance of large-scale magnetic fields in barred galaxies. We take a velocity field (with strong noncircular components) from a published gas dynamical simulation of Athanassoula (1992), and use this as input to a galactic dynamo calculation.

The Bochum Survey of the Southern Galactic Disk: IV. Multi‐Band Photometry
Astronomische Nachrichten, EarlyView.ABSTRACT The Southern Galactic Disk Survey (GDS) monitored a mosaic of 268 fields along a 6°‐wide stripe in the southern galactic disk from September 2010 to September 2019. These fields were observed between 21 and 407 times sim r′$$ {r}^{\prime } $$ultaneously in (8mag≲r′≲18mag$$ 8\kern0.6em \mathrm{mag}\lesssim {r}^{\prime}\lesssim 18\kern0.6em ...

On the topology of global coronal magnetic fields [PDF]
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.The decline of seagrass meadows is a continuing global concern, and seed‐based restoration provides a scalable approach to recovering lost and degraded meadows. Such approaches require large quantities of seed to be collected, processed, and often stored for months until deployment.

The Galaxy Magnetic Field [PDF]
International Astronomical Union Colloquium, 1977 The origin and dynamics of magnetic fields depend crucially on the dynamics of a gas in the Galaxy. In turn the magnetic field is needed to isotropize the cosmic rays (the influence on chemistry) and is of importance for the formation of stars (local dynamics). Thus the appearance of this topic at the Colloquium is justified.

Magnetic Fields in Galaxy Clusters [PDF]
Highlights of Astronomy, 2005 AbstractMagnetic fields in galaxy clusters can be investigated using a variety of techniques. Recent studies including radio halos, Inverse Compton hard X-ray emissions and Faraday rotation measure, are briefly outlined. A numerical approach for investigating cluster magnetic fields strength and structure is presented.

Liquid Biopsy: Past, Present, and Future
MedComm, Volume 7, Issue 11, November 2026.Liquid biopsy has expanded from cancer genotyping to a broader strategy for probing both oncologic and nononcologic conditions through circulating analytes and multilayer molecular readouts. This review traces the field's past, present, and future—summarizing where liquid biopsy is most actionable today, why performance varies across contexts, and ...

Cosmic magnetic fields from density perturbations
, 2023 reservedMagnetic fields are observed on nearly all scales in the Universe, from stars and galaxies up to galaxy clusters and even beyond. The origin of cosmic magnetic fields remains an open question; however, a large class of models puts its origin in ...
