We compare the constraining power of redshift drift measurements by the Extremely Large Telescope (ELT), as studied by Liske et\u00a0al., with that of two recently proposed alternatives: the cosmic accelerometer of Eikenberry et\u00a0al., and the differential redshift drift of Cooke. We find that the cosmic accelerometer with a 6-yr baseline leads to weaker constraints than those of the ELT (by 60\u2009per cent); however, with identical time baselines it outperforms the ELT by up to a factor of 6. The differential redshift drift always performs worse than the standard approach if the goal is to constrain the matter density; however, it can perform significantly better than it if the goal is to constrain the dark energy equation of state. Our results show that accurately measuring the redshift drift and using these measurements to constrain cosmological parameters are different merit functions: an experiment optimized for one of them will not be optimal for the other. These non-trivial trade-offs must be kept in mind as next-generation instruments enter their final design and construction phases.<\/jats:p>","DOI":"10.1093\/mnrasl\/slab102","type":"journal-article","created":{"date-parts":[[2021,8,27]],"date-time":"2021-08-27T12:33:39Z","timestamp":1630067619000},"page":"L53-L57","source":"Crossref","is-referenced-by-count":15,"title":["Cosmological impact of redshift drift measurements"],"prefix":"10.1093","volume":"508","author":[{"given":"J","family":"Esteves","sequence":"first","affiliation":[{"name":"Universit\u00e9 de Montpellier , 163 Rue Auguste Broussonnet, F-34090 Montpellier, France"},{"name":"Centro de Astrof\u00edsica da Universidade do Porto , 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 G","family":"Pereira","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"},{"name":"Faculdade de Ci\u00eancias, Universidade do Porto , Rua do Campo Alegre, P-4150-007 Porto, Portugal"}]},{"given":"C S","family":"Alves","sequence":"additional","affiliation":[{"name":"Centro de Astrof\u00edsica da Universidade do Porto , Rua das Estrelas, P-4150-762 Porto, Portugal"},{"name":"Department of Physics and Astronomy , University College London, Gower Street, London WC1E 6BT, UK"}]}],"member":"286","published-online":{"date-parts":[[2021,8,27]]},"reference":[{"key":"2023121923293405000_bib1","doi-asserted-by":"publisher","first-page":"3607","DOI":"10.1093\/mnras\/stz1934","volume":"488","author":"Alves","year":"2019","journal-title":"MNRAS"},{"key":"2023121923293405000_bib2","doi-asserted-by":"publisher","first-page":"2","DOI":"10.1007\/s41114-017-0010-3","volume":"21","author":"Amendola","year":"2018","journal-title":"Living Rev.
