Description
We present a kinematic analysis of the double-barred early-type galaxy NGC 357. The radial velocity and velocity dispersion profiles along both the nuclear bar axis and the semi-major axis clearly reveal the presence of the two bars. The results indicate that the bulge is pressure supported whereas the |vr|/σ ratio shows a plateau along the nuclear bar.

Starbursts in Galaxies GEFE
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
