The hydrogen gas in high redshift galaxies is fully ionised

In their 2008 publication, Stephen Curran and colleagues discussed their study of far-away galaxies that are devoid of cool hydrogen gas – the fuel for star formation. Since observing distant galaxies also means looking far back in time (in this case, 11.5 billion...

Do gamma-ray bursts produce Lorimer bursts?

Since Lorimer et al. (2007) reported the detection of a single short and bright radio burst that could be traced back to extragalactic origin, astronomers have tried to come up with plausible models to explain the observation and have conducted surveys to detect more...
