Merger Interactions Enhance Star Formation Rates in Galaxy Group Housing QSO PKS0405-123 and Gaseous Nebulae.

Abstract (from CDS):

The star formation rate (SFR) of galaxies can change due to interactions between galaxies, stellar feedback ejection of gas into the circumgalactic medium, and energy injection from accretion onto black holes. However, it is not clear which of these processes dominantly alters the formation of stars within galaxies. Johnson et al. reported the discovery of large gaseous nebulae in the intragroup medium of a galaxy group housing QSO PKS0405-123 and hypothesized they were created by galaxy interactions. We identify a sample of 30 group member galaxies at z ∼ 0.57 from the Very Large Telescope/Multi Unit Spectroscopic Explorer observations of the field and calculate their [O II]λλ3727,3729 SFRs in order to investigate whether the QSO and nebulae have affected the SFRs of the surrounding galaxies. We find that star formation is more prevalent in galaxies within the nebulae, signifying galaxy interactions are fueling higher SFRs.
