Evolution of the circular velocity at the distance of the Sun (R_⊙ ∼ 8.12 kpc; Gravity Collaboration 2019) in the Galactic disk as a function of backward-integration time in five TNG-TVPs, first and third panels. A straight line indicates the current velocity value of the solar rotation (V_⊙ ∼ 235 km s⁻¹; Mardini et al. 2020). Dotted green lines represent the original data from the IllustrisTNG-100. Dotted blue lines represent the interpolation and smoothing with a time step of 1 Myr. Second and fourth panels: Evolution of the TNG-TVP rotation curves at the initial (at present in red), average (5 Gyr in green), and final moments of time (10 Gyr in blue). From left to right from top to bottom: 411321, 441327, 451323, 462077, and 474170.
