Info

Early sciences with FAST– bilateral meeting in JBO• HI – small scale deep survey of H-z• Pulsar – BH binary• M31 – extragalactic pulsars• Survey more pulsars in clusters, more about this by Scott• OH masers at z ~ 1• Lines in Orion e.g. C20H10 ? By DiFollow-ups of LOFAR/ASKAP ….Make use of the whole 500maperture by adopting a longlinear feed to achieve ?10
