Cosmic-Ray Propagation and Interactions in the Galaxy [PDF]
Annual Review of Nuclear and Particle Science, 2007 We survey the theory and experimental tests for the propagation of cosmic rays in the Galaxy up to energies of 1015eV. A guide to the previous reviews and essential literature is given, followed by an exposition of basic principles. The basic ideas of cosmic-ray propagation are described, and the physical origin of its processes is explained.

Bar-spheroid interaction in galaxies
The Astrophysical Journal, 1992 The secular evolution of barred galaxies is explored using N-body simulation and linear analysis. In particular, we examine the interaction between bars and spheroidal components of galaxies. According to our calculations, this interaction drives secular transfer of angular momentum from bars to spheroids, primarily through resonant coupling.

TeV Diffuse Emission From the Inner Galaxy
Frontiers in Astronomy and Space Sciences, 2018 The TeV diffuse emission from the Galactic plane is produced by multi TeV electrons and nuclei interacting with radiation fields and ambient gas, respectively. Measurements of the TeV diffuse emission help constrain CR origin and transport properties. We

The Astrophysical Journal Letters, 2023 Extreme emission line galaxies (EELGs), where nebular emissions contribute 30%–40% of the flux in certain photometric bands, are ubiquitous in the early Universe ( z > 6).

Scale Interactions and Galaxy Evolution [PDF]
Astrophysics and Space Science, 2003 To understand galaxies and their evolution, it is necessary to describe how the different scales interact: how the microscopic physics, such as star formation, or the large scale physics, such as galaxy interactions may modify the galaxy global shapes.

S8 Tension in the Context of Dark Matter–Baryon Scattering
The Astrophysical Journal Letters, 2023 We explore an interacting dark matter (IDM) model that allows for a fraction of dark matter (DM) to undergo velocity-independent scattering with baryons. In this scenario, structure on small scales is suppressed relative to the cold DM scenario.

Surrogate‐Optimized Flow‐Guided Miniature Condenser for Rapid Exhaled Glucose Detection
Advanced Materials Technologies, EarlyView.A surrogate‐optimized miniature condenser guides humid exhaled flow toward cold surfaces to accelerate exhaled breath condensate collection. By improving vapor access within a compact footprint, the design increases sample yield. This enables post‐collection enrichment and rapid colorimetric glucose detection from dilute exhaled biomarkers within a 5 ...
