　　Speaker: Dr. Jeff Wagg

　　Affiliation: SKA Headquarter, Manchester, United Kingdom

　　Speaker Info: Dr. Jeff Wagg is a Canadian astronomer who completed his PhD at the INAOE, Mx and the Harvard-Smithsonian Center for Astrophysics. He went on to work as a Max-Planck/NRAO Fellow at NRAO in Socorro, and his main area of research has been the study of gas and dust in high-redshift galaxies. He was an ESO Fellow working on ALMA commissioning in Chile before spending a year at the Cambridge Cavendish Laboratory. Since 2013 he has been a project scientist at the Square Kilometre Array Organisation in the UK.

　　Abstract: We are currently living in a golden age for radio astronomy. The global suite of radio-wavelength facilities are revealing incredible discoveries in all areas of science ranging from the early Universe to the pulsars in our own galaxy. This science will be enhanced in the decades ahead by the two SKA1 telescopes: SKA1-MID in the Karoo, and SKA1-LOW in Western Australia. Construction activities are scheduled to begin in 2021. In this presentation I will provide an overview of some of the SKA pathfinders and precursors and highlight a few of their recent discoveries. This science has guided the design of SKA1, and I will summarise the current specifications and status of the construction planning. I will end by providing an update of the science activities and opportunities for the community.
