I will give an update on ASKAP and present some of the new results from the telescope. In particular, I will focus on early science results from the main HI extragalactic survey: WALLABY. This survey is expected to detect HI in ~ 500,000 galaxies, out to z = 0.26, and will examine the properties and large-scale distribution of these galaxies. I will present images of the nearby, gas-rich spiral galaxy IC 5201 and 3 gas-rich dwarf satellite galaxies. These are the highest resolution HI images for IC 5201 and the first time its satellites have been detected in HI. We have used ancillary multi-wavelength data to study the physics of the galaxy group, in order to understand what is driving the cool gas and star formation in the galaxies. Finally, I will discuss the future of ASKAP and MeerKAT, and the involvement of the MeerKAT Fornax (OAC) team with these telescopes.       <\/p>\n","protected":false},"template":"","class_list":["post-4564","seminari","type-seminari","status-publish","hentry","categorie_seminari-colloquium"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/seminari\/4564","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/seminari"}],"about":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/types\/seminari"}],"wp:attachment":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/media?parent=4564"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
