Dr Emil Lenc (CSIRO)

ASKAP and its role in the SKA era.


The Australian Square Kilometre Array Pathfinder is a telescope with unique capabilities and great potential to revolutionise the way we observe the Universe. I will give a brief overview of the telescope, why we have built it, how it fits in with the Square Kilometre Array grand design, and the science it is designed to perform. I will conclude with a sneak preview of science results that have been made to date.

Bio- Emil Lenc

Emil is a senior research scientist working at CSIRO Astronomy & Space Science as part of the ASKAP Commissioning and Early Science (ACES) team to help commission the Australian Square Kilometre Array Pathfinder (ASKAP) and ultimately use the telescope for science. He was previously with the University of Sydney where he worked to commission the Murchison Widefield Array (MWA) and worked with Bryan Gaensler on polarimetry and later with Tara Murphy on transient science. His main interests are to use telescopes in ways that utilise their unique qualities and get the most science out of them.
