SINFONI maps of H-alphaline emission in BzK-15504, separated in 65 km/s bins of Doppler velocity (marked at the bottom left of each image) and centred on the systemic cosmological redshift of the galaxy (z=2.38). North is up and East is to the left, and a bar marks the angular scale of 0.5". The high resolution, spectrally resolved images show with exquisite clarity that star formation in this distant galaxy occurs in spectacular luminous complexes (bright spots) and that gas is funnelled at large rates into the nuclear region, forming a dense stellar bulge there. Over time, this system may transform into a compact, dense elliptical galaxy.
