The Larson-Tinsley Effect in the UV: Interacting vs. `Normal' Spiral Galaxies
, 2010 We compare the UV-optical colors of a well-defined set of optically-selected pre-merger interacting galaxy pairs with those of normal spirals. The shorter wavelength colors show a larger dispersion for the interacting galaxies than for the spirals.

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

Back to the green valley: how to rejuvenate an S0 galaxy through minor mergers
, 2015 About half of the S0 galaxies in the nearby Universe show signatures of recent or ongoing star formation. Whether these S0 galaxies were rejuvenated by the accretion of fresh gas is still controversial.

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.

The unusual distribution of molecular gas and star formation in Arp 140 [PDF]
, 2006 We investigate the atomic and molecular interstellar medium and star formation of NGC 275, the late-type spiral galaxy in Arp 140, which is interacting with NGC 274, an early-type system.

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.

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.

Malin 1: interacting galaxy pair?
, 2010 Malin 1 is a unique, extraordinarily large low surface brightness galaxy. The structure and the origins of the galaxy are poorly understood. The reason for such a situation is an absence of detailed observational data, especially, of high-resolution ...
