TNG50 Infinite Galleries

H-alpha light maps, velocity maps and velocity profiles for the star-forming gaseous component of random galaxies, from the TNG50 simulation, as in Figure 11 of Pillepich+ (2019). Galaxies with stellar mass above 10¹⁰ solar masses are shown at z=1 and z=2. In the three leftmost panels, we show edge-on projections of H-alpha light and mean line-of-sight velocity, in addition to the radial profiles of the mean line-of-sight velocity along the slit depicted by the white solid lines. In the three rightmost panels, we show the face-on projections of H-alpha light and of the line-of-sight velocity dispersion, in addition to the average velocity dispersion profiles along the slit. We always pixelize using square pixels of 0.5 comoving kpc to a side. For each galaxy, two numbers are indicated in the panels: gas rotation velocity (Vrot) and gas dispersion (sigma).
