Most simulations to date have implied that satellite galaxies traveling through galaxy clusters are stripped of gas for future star formation in a process known as “strangulation”. In contrast, the authors of this paper suggest that satellite galaxies may not be as cut off as some might think: instead, their simulations show that the cooler, stripped gas from the corona will mix with the surrounding intra-cluster medium and remain near the original galaxy as a potential new source of star-forming fuel.

V1309 Sco first caught astronomers attention in 2008, when it displayed an outburst, suddenly getting a hundred times brighter. Due its location near the Galactic center, V1309 Sco has been monitored by the OGLE, which is looking for microlensing events, since 2001. The authors of this paper were able to look back into this archive of data and see what V1309 Sco was doing before it erupted.
