Description
We measured the stellar kinematics of three face-on galaxies with the
aim of searching for box/peanut-shaped (B/P) bulges. These observations
test and confirm that face-on B/P bulges can be recognized by two minima
in the radial profile of the fourth Gauss-Hermite moment h_4 of the
line-of-sight velocity distribution measured along the bar major axis.
In NGC 98, a clear double minimum in h_4 is present before the end of
the bar, as predicted. In contrast, in NGC 600, which is also a barred
galaxy but lacks a substantial bulge, we do not find any significant
kinematic signature for a B/P bulge. In NGC 1703, which is an unbarred
galaxy, we found no evidence of a B/P bulge.

Starsbursts play a key role in the cosmic evolution of galaxies, and thus in the star formation (SF) history of the universe, the production of metals, and the feedback coupling galaxies with the cosmic web. Extreme SF conditions prevail early on during the formation of the first stars and galaxies, therefore, the starburst phenomenon constitutes a
