DOI: 10.1093/mnras/stad1061
Abstract: Using the data set of The Three Hundred project, i.e. 324 hydrodynamical resimulations of cluster-sized haloes and the regions of radius 15 h−1 Mpc around them, we study galaxy pairs in high-density environments. By projecting the… read more here.

DOI: 10.1093/mnras/stad1300
Abstract: Observations of the nearby universe reveal an increasing fraction of active galactic nuclei (AGN) with decreasing projected separation for close galaxy pairs, relative to control galaxies. This implies galaxy interactions play a role in enhancing… read more here.

DOI: 10.1093/mnras/sty2042
Abstract: We present Gemini Multi-Object Spectrograph (GMOS) spectra of HI-rich tidal features located around the outskirts of two interacting galaxy pairs, NGC 3166/9 and NGC 4725/47. These follow-up observations are part of a multi-wavelength campaign to… read more here.
