What's Killing Galaxies?

Galaxies are being killed in one of the most extreme regions of the nearby Universe and astronomers want to know why. A recently published paper, which will be featured in the December edition of the Astrophysical Journal Supplement Series, provides the clearest evidence yet, that the environments surrounding galaxies can reach far within the galaxies and have a lethal impact on the fuel needed to birth new stars: their molecular gas.

The Canadian-led paper from a collaboration of 36 international astronomers, which includes Christine Wilson, Distinguished University Professor at McMaster and a principal investigator, presents state-of-the-art observations of molecular gas in 51 galaxies belonging to the Virgo Cluster.
