The complete characterization of the pressure profile of high-redshift galaxy clusters , from their core to their outskirts , is a major issue for the study of the formation of large-scale structures .
It is essential to constrain a potential redshift evolution of both the slope and scatter of the mass-observable scaling relations used in cosmology studies based on cluster statistics .
In this paper , we present the first thermal Sunyaev-Zel ’ dovich ( tSZ ) mapping of a cluster from the sample of the New IRAM Kids Arrays ( NIKA2 ) SZ large program that aims at constraining the redshift evolution of cluster pressure profiles and the tSZ-mass scaling relation .
We observed the galaxy cluster PSZ2 G144.83 + 25.11 at redshift z = 0.58 with the NIKA2 camera , a dual-band ( 150 and 260 GHz ) instrument operated at the Institut de Radioastronomie Millimétrique ( IRAM ) 30-meter telescope .
We identify a thermal pressure excess in the south-west region of PSZ2 G144.83 + 25.11Â and a high-redshift sub-millimeter point source that affect the intracluster medium ( ICM ) morphology of the cluster .
The NIKA2 data are used jointly with tSZ data acquired by the Multiplexed SQUID/TES Array at Ninety Gigahertz ( MUSTANG ) , Bolocam , and Planck  experiments in order to non-parametrically set the best constraints on the electronic pressure distribution from the cluster core ( R \sim 0.02 { R _ { 500 } } ) to its outskirts ( R \sim 3 { R _ { 500 } } ) .
We investigate the impact of the over-pressure region on the shape of the pressure profile and on the constraints on the integrated Compton parameter { Y _ { 500 } } .
A hydrostatic mass analysis is also performed by combining the tSZ-constrained pressure profile with the deprojected electronic density profile from XMM- Newton .
This allows us to conclude that the estimates of { Y _ { 500 } } and { M _ { 500 } } obtained from the analysis with and without masking the disturbed ICM region differ by 65 % Â and 79 % respectively .
This work highlights that NIKA2 will have a crucial impact on the characterization of the scatter of the { Y _ { 500 } } - { M _ { 500 } } scaling relation due to its high potential to constrain the thermodynamic and morphological properties of the ICM when used in synergy with X-ray observations of similar angular resolution .
This study also presents the typical products that will be delivered to the community for all clusters included in the NIKA2 tSZ Large Program .
