The Astrophysical Journal Letters, 2023 A primary new capability of JWST is the ability to penetrate the dust in star-forming galaxies to identify and study the properties of young star clusters that remain embedded in dust and gas. In this Letter we combine new infrared images taken with JWST

Fractal basins of escape and the formation of spiral arms in a galactic potential with a bar [PDF]
, 2014 We investigate the dynamics in the close vicinity of and within the critical area in a 2D effective galactic potential with a bar of Zotos. We have calculated Poincar\'e surfaces of section and the basins of escape.

Stellar dynamics around transient co-rotating spiral arms
EPJ Web of Conferences, 2012 Spiral density wave theory attempts to describe the spiral pattern in spiral galaxies in terms of a long-lived wave structure with a constant pattern speed in order to avoid the winding dilemma.

Aggregate, EarlyView.Tau amyloid corona‐shelled nanoparticles (TACONs) were synthesized by incubating gold nanoparticles (AuNPs) with tau monomers that had been pre‐reacted with heparin. These TACONs represent a promising high‐throughput screening platform for identifying tau oligomer degraders as potential therapeutic agents for Alzheimer's disease.

Inner Molecular Rings in Barred Galaxies: BIMA SONG CO Observations
, 2002 Although inner star-forming rings are common in optical images of barred spiral galaxies, observational evidence for the accompanying molecular gas has been scarce.

A New Statistical Analysis of the Morphology of Spiral Galaxies
The Astronomical JournalMorphology is the starting point for understanding galaxies. Elmegreen et al. classified spiral galaxies into flocculent, multiple-arm, and grand-design galaxies based on the regularity of their spiral arm structure.

J0107a: A Barred Spiral Dusty Star-forming Galaxy at z = 2.467
The Astrophysical Journal Letters, 2023 Dusty star-forming galaxies (DSFGs) are among the most massive and active star-forming galaxies during the cosmic noon. Theoretical studies have proposed various formation mechanisms of DSFGs, including major merger-driven starbursts and secular star ...

The Stochastic‐Dissipative Störmer Problem‐Trajectories and Radiation Patterns
Annalen der Physik, EarlyView.We consider charged particle motion and radiation in a dipole magnetic field, in the presence of friction and of stochastic forces. The numerical solutions of the Langevin equation reveal how these forces modify the complex dynamics of particles, and they offer some new insights into the nonlinear processes relevant to planetary radiation belts ...

The Visibility of Galactic Bars and Spiral Structure At High Redshifts [PDF]
, 2002 We investigate the visibility of galactic bars and spiral structure in the distant Universe by artificially redshifting 101 B-band CCD images of local spiral galaxies from the Ohio State University Bright Spiral Galaxy Survey. Our artificially redshifted

Somato‐Cognitive Action Network in Focal Dystonia
Movement Disorders, EarlyView.Abstract Background The central pathology causing idiopathic focal dystonia remains unclear. The recently identified somato‐cognitive action network (SCAN) has been implicated. Objective We tested whether the effector‐agnostic SCAN may constitute a central pathology shared across dystonia subtypes, whereas the effector‐specific regions in the primary ...
