The latter, probing lower redshifts, enables us to watch the Universe\u2019s acceleration era in real time, while the former does the same for the matter era. We use Fisher matrix analysis techniques, which we show to give comparable results to those of a Markov Chain Monte Carlo approach, to discuss forecasts for SKAO measurements of the redshift drift and their cosmological impact. We consider specific fiducial cosmological models but mainly rely on a more agnostic cosmographic series (which includes the deceleration and jerk parameters), and we also discuss prospects for measurements of the drift of the drift. Overall, our analysis shows that SKAO measurements, with a reasonable amount of observing time, can provide a competitive probe of the low-redshift accelerating Universe.<\/jats:p>","DOI":"10.1093\/mnras\/stad3884","type":"journal-article","created":{"date-parts":[[2023,12,19]],"date-time":"2023-12-19T06:50:02Z","timestamp":1702968602000},"page":"9918-9929","source":"Crossref","is-referenced-by-count":5,"title":["Watching the Universe\u2019s acceleration era with the SKAO"],"prefix":"10.1093","volume":"527","author":[{"given":"C M J","family":"Marques","sequence":"first","affiliation":[{"name":"Centro de Astrof\u00edsica da Universidade do Porto , Rua das Estrelas, P-4150-762 Porto , Portugal"},{"name":"Faculdade de Ci\u00eancias, Universidade do Porto , Rua do Campo Alegre, P-4150-007 Porto , Portugal"},{"name":"Instituto de Astrof\u00edsica e Ci\u00eancias do Espa\u00e7o, CAUP , Rua das Estrelas, P-4150-762 Porto , Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4886-9261","authenticated-orcid":false,"given":"C J A P","family":"Martins","sequence":"additional","affiliation":[{"name":"Centro de Astrof\u00edsica da Universidade do Porto , Rua das Estrelas, P-4150-762 Porto , Portugal"},{"name":"Instituto de Astrof\u00edsica e Ci\u00eancias do Espa\u00e7o, CAUP , Rua das Estrelas, P-4150-762 Porto , Portugal"}]},{"given":"B","family":"Gilabert\u00a0L\u00f3pez","sequence":"additional","affiliation":[{"name":"Faculty of Physics, University of Barcelona , Mart\u00ed i Franqu\u00e8s 1-11, E-08028 Barcelona , Spain"}]}],"member":"286","published-online":{"date-parts":[[2023,12,18]]},"reference":[{"year":"2006","author":"Albrecht","key":"2023122718402239200_bib1"},{"year":"2009","author":"Albrecht","key":"2023122718402239200_bib2"},{"key":"2023122718402239200_bib3","doi-asserted-by":"publisher","first-page":"3607","DOI":"10.1093\/mnras\/stz1934","volume":"488","author":"Alves","year":"2019","journal-title":"MNRAS"},{"key":"2023122718402239200_bib4","doi-asserted-by":"publisher","first-page":"093","DOI":"10.1088\/1475-7516\/2023\/11\/093","volume":"2023","author":"Bessa","year":"2023","journal-title":"J.
