TL;DR: In this article, the authors investigate the origin of any deviations across finders in a comparison of different methods and techniques, and conclude that the prime contribution to differences in halo properties across codes stems from the distinct particle collection methods and -to a minor extent -the particular aspects of how the procedure for removing unbound particles is implemented.

TL;DR: In this paper, a comparison of spin distributions of subhaloes found associated with a host halo was performed in two cosmological simulation families of Milky Way-like galaxies, namely the Aquarius and GHALO simulations.

TL;DR: In this article, the authors investigated the main mechanism(s) that regulate specific star formation rate (SSFR) in nearby galaxies, cross-correlating two proxies of this quantity with other physical properties (mass, metallicity, environment, morphology, and the presence of close companions) in a sample of $\sim82500$ galaxies extracted from the Sloan Digital Sky Survey (SDSS).

On the nature of diffuse ionized gas in galaxies -- I The contribution of dust scattering to diffuse line emission
TL;DR: In this article, the contribution of dust scattering to the diffuse H-alpha emission observed in nearby galaxies was investigated and it was shown that the flux arising from scattered light is of the order of 1-2 per cent of the H alpha flux coming directly from the HII regions.

Galaxy evolution on resolved scales: ageing and quenching in CALIFA
TL;DR: In this article, the fundamental mechanism(s) that drive galaxy evolution in the Local Universe was investigated by comparing two proxies of star-formation sensitive to different timescales, such as EW(H$\alpha$) and colours like $g-r$, one may distinguish between smooth secular evolution (ageing) and sudden changes (quenching) on the recent star formation history of galaxies.
