dc.description.abstractContext. Ultraluminous infrared galaxies (ULIRGs) are characterised by extreme starburst (SB) and active galactic nucleus (AGN) activity, and are therefore ideal laboratories to study the outflow phenomena and their feedback e ects. We have recently started the “Physics of ULIRGs with MUSE and ALMA” (PUMA) project, a survey of 25 nearby (z < 0:165) ULIRGs observed with the integral field spectrograph MUSE and the interferometer ALMA. This sample includes systems with both AGN and SB nuclear activity in the pre- and post-coalescence phases of major mergers. Aims. The main goals of the project are: (i) study the prevalence of (ionised, neutral and molecular) outflows as a function of the galaxy properties, (ii) constrain the driving mechanisms of the outflows (e.g. discriminate between SB and AGN winds), (iii) identify and characterise the presence of feedback e ects on the host galaxy. In this first paper, we present details on the sample selection, MUSE observations and data reduction, and the derivation of first high-level data products. Methods. MUSE data cubes are analysed to study the dynamical status of each of the 21 ULIRGs so far observed, taking into account the stellar kinematics and the morphological properties inferred from MUSE narrow-band images. We also locate the ULIRG nuclei, taking advantage of near-infrared (HST) and mm (ALMA) data, and study their optical spectra to infer (i) the ionisation state via standard optical line ratio diagnostics, and (ii) the presence of outflows in both atomic ionised ([OIII], H ) and neutral (NaID) gas. Results. We show a good consistency between the morphological and stellar kinematic classifications, proving that post-coalescence systems are more likely associated with ordered motions, while interacting (binary) systems are dominated by non-ordered and streaming motions. We also find broad and asymmetric [OIII] and NaID profiles in almost all nuclear spectra, with linewidths in the range [300􀀀2000] km/s, possibly associated with AGN- and SB-driven winds. This result reinforces previous findings indicating that outflows are ubiquitous during the pre- and post-coalescence phases of major mergers.
