Infrared mergers and infrared quasi-stellar objects with galactic winds – II. NGC 5514: two extranuclear starbursts with LINER properties and a supergiant bubble in the rupture phase

A study of the morphology, kinematics and ionization structure of the IR merger NGC5514, is here presented. This study is based mainly on INTEGRAL twodimensional (2D) spectroscopy (obtained at the 4.2 m William Herschel Telescope, WHT), plus optical and near IR images. Clear evidence of two extra-nuclear starbursts with young outflows (OFs) and LINER activity are reported. One of these OFs has generated a supergiant bubble and the other is associated with an extended complex of H ii region. In the galactic bubble it was found that: (i) the [S ii], H�, [N ii], [O i] and [O iii] emission line maps show a bubble with a distorted ellipsoidal shape, with major and minor axes of �6.5 kpc (13.
