We investigate the shape of the Rotation Curves ( RCs ) of z \sim 1 star-forming galaxies and compare them with the local star-forming galaxies .
For this purpose , we have used 409 galaxies from the K-band Multi-Object Spectrograph ( KMOS ) for Redshift One Spectroscopic Survey ( KROSS ) .
This sample covers the redshift range 0.57 \leq z \leq 1.04 , effective radii 0.69 \leq R _ { e } \left [ kpc \right ] \leq 7.73 , absolute H-band magnitude -24.46 \leq M _ { H } \leq - 18.85 with median stellar mass log \left ( M _ { * } \left [ M _ { \odot } \right ] \right ) = 9.95 and median total star-formation rate log \left ( SFR _ { tot } \left [ M _ { \odot } yr ^ { -1 } \right ] \right ) = 1.49 .
Using ^ { 3 D } BAROLO ( Barolo ) , we extract H \alpha kinematic maps and corresponding Rotation Curves ( RCs ) .
The main advantage of Barolo is that it incorporates the beam smearing in the 3D observational space , which provide us with the intrinsic rotation velocity even in the low spatial resolution data .
Using Asymmetric Drift Correction ( ADC ) , we have corrected the RCs for the pressure gradient effect , which seems to be a more dominant effect than beam smearing in high-z galaxies .
Nearly all objects ( 0.1 < v / \sigma < 15 ) are affected by the pressure gradient , and we noticed that ADC improves the rotation velocity of these systems by \sim 10 - 87 \% .
Only a combination of the three techniques ( 3D-kinematic modelling + 3D-Beamsmearing correction + ADC ) yields the intrinsic RC of an individual galaxy .
Further , we present the co-added RCs constructed out of 237 high-quality objects to obtain intrinsic RC shapes out to 6.4 \times disk scale length .
We do not see any change in the shape of RCs with respect to the local star-forming disk-type galaxies .
In contrast , we do find a significant evolution in the stellar-disk length ( R _ { D } ) of the galaxies .
Therefore , we conclude stellar disk evolves over cosmic time while total mass distribution stays constant .
