text:   galaxies in the local Universe",4,"['New paper out today! <LINK>\nVery pleased with this one: looking at cold gas inflows and outflows in local, normal galaxies using stacking techniques of SDSS spectra - aiming to constrain the strength/properties of the flows and whether they can quench the galaxy! <LINK>', 'In the local Universe, two populations of galaxies are observed: blue+star-forming and red+passive galaxies that have stopped forming stars. The general consensus is that galaxies transit from this blue population to the red one - ie., something is quenching the star formation. https://t.co/joi7BKF32y', 'One of the major unanswered questions in astronomy is how does this happen? Here we look at the role of galaxy outflows and aim to constrain whether they can expel enough Hydrogen gas out of the galaxy - thereby removing the ""fuel"" for star formation - to ""quench"" the host. https://t.co/fLvv55ZLfR', 'Many authors have done great work on this, but generally looked at extreme objects with somewhat incomplete data sets. Here we expand on this by looking at all galaxy populations with one of the largest astronomical surveys to date (@sdssurveys).']",18,07,1085
