TL;DR: In this paper, the authors analyzed the H I emission of 22 tidal tail regions of the Mullan et al. sample of pairwise interacting galaxies and measured the column densities, line-of-sight velocity dispersions, and kinetic energy densities on ~kpc scales.

TL;DR: In this paper, the impact of the first dredge-up on the surface chemical patterns of red giant branch (RGB) stars has been investigated, and it was shown that for a given initial range of light element abundances, the dredge up reduces the predicted RGB widths in N-sensitive filters compared to the case when its effect on the stellar spectral energy distributions is not accounted for.

TL;DR: In this paper, the authors present a spectroscopic survey of 21 young massive clusters and complexes and one tidal dwarf galaxy candidate (TDG) in Stephan's Quintet, an interacting compact group of galaxies.

TL;DR: The theory and observations of cluster disruption are reviewed, both the suggested initial rapid dissolution phase (infant mortality) and the longer timescale processes that affect clusters after they emerge from their progenitor GMCs are reviewed.

TL;DR: In this paper, the authors combine Spitzer IRAC mid-infrared and ChandraX-ray observations of the dominant galaxies NGC 6872 and NGC6876 in the Pavo group with archival optical and HI data to study interaction-induced star formation.
