It is essential for a robust calibration of the mass-observable scaling relations and their scatter, which are key ingredients for precise cosmology using cluster statistics. Here we illustrate an application of high resolution (<20 arcsec) thermal Sunyaev-Zel’dovich (tSZ) observations by probing the intracluster medium (ICM) of the Planck-discovered galaxy cluster PSZ1 G045.85+57.71 at redshift z = 0.61, using tSZ data obtained with the NIKA camera, which is a dual-band (150 and 260 GHz) instrument operated at the IRAM 30-m telescope. We deproject jointly NIKA and Planck data to extract the electronic pressure distribution from the cluster core (R ~ 0.02 R500) to its outskirts (R ~ 3 R500) non-parametrically for the first time at intermediate redshift. The constraints on the resulting pressure profile allow us to reduce the relative uncertainty on the integrated Compton parameter by a factor of two compared to the Planck value. Combining the tSZ data and the deprojected electronic density profile from XMM-Newton allows us to undertake a hydrostatic mass analysis, for which we study the impact of a spherical model assumption on the total mass estimate. We also investigate the radial temperature and entropy distributions. These data indicate that PSZ1 G045.85+57.71 is a massive (M500 ~ 5.5 × 1014M⊙) cool-core cluster. This work is part of a pilot study aiming at optimizing the treatment of the NIKA2 tSZ large program dedicated to the follow-up of SZ-discovered clusters at intermediate and high redshifts. This study illustrates the potential of NIKA2 to put constraints on thethermodynamic properties and tSZ-scaling relations of these clusters, and demonstrates the excellent synergy between tSZ and X-ray observations of similar angular resolution.</description><identifier>ISSN: 0004-6361</identifier><identifier>EISSN: 1432-0746</identifier><identifier>EISSN: 1432-0756</identifier><identifier>DOI: 10.1051/0004-6361/201629405</identifier><language>eng</language><publisher>EDP Sciences</publisher><subject>Astrophysics ; cosmology: observations ; galaxies: clusters: intracluster medium ; instrumentation: high angular resolution ; Physics</subject><ispartof>Astronomy and astrophysics (Berlin), 2017, Vol.597, p.A110</ispartof><rights>Distributed under a Creative Commons Attribution 4.0 International License</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c323t-feaa8c455486c859a0e70e2f4502b5fedb12e22032ae14b51ef8f1948563dcaf3</citedby><cites>FETCH-LOGICAL-c323t-feaa8c455486c859a0e70e2f4502b5fedb12e22032ae14b51ef8f1948563dcaf3</cites><orcidid>0000-0003-3201-0185 ; 0009-0009-2877-2954 ; 0000-0001-9995-4792 ; 0000-0001-6937-5052 ; 0000-0001-8488-3645 ; 0009-0000-5380-1109</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>230,314,776,780,881,3714,4010,27900,27901,27902</link.rule.ids><backlink>$$Uhttps://in2p3.hal.science/in2p3-01349507$$DView record in HAL$$Hfree_for_read</backlink></links><search><creatorcontrib>Ruppin, F.</creatorcontrib><creatorcontrib>Adam, R.</creatorcontrib><creatorcontrib>Comis, B.</creatorcontrib><creatorcontrib>Ade, P.</creatorcontrib><creatorcontrib>André, P.</creatorcontrib><creatorcontrib>Arnaud, M.</creatorcontrib><creatorcontrib>Beelen, A.</creatorcontrib><creatorcontrib>Benoît, A.</creatorcontrib><creatorcontrib>Bideaud, A.</creatorcontrib><creatorcontrib>Billot, N.</creatorcontrib><creatorcontrib>Bourrion, O.</creatorcontrib><creatorcontrib>Calvo, M.</creatorcontrib><creatorcontrib>Catalano, A.</creatorcontrib><creatorcontrib>Coiffard, G.</creatorcontrib><creatorcontrib>D’Addabbo, A.</creatorcontrib><creatorcontrib>De Petris, M.</creatorcontrib><creatorcontrib>Désert, F.-X.</creatorcontrib><creatorcontrib>Doyle, S.</creatorcontrib><creatorcontrib>Goupy, J.</creatorcontrib><creatorcontrib>Kramer, C.</creatorcontrib><creatorcontrib>Leclercq, S.</creatorcontrib><creatorcontrib>Macías-Pérez, J.
