Descripción
We present new near-infrared images and spectra of the circumnuclear star formation regions in M100. Images in J, H, and K have been obtained in conditions of 0.3'' seeing using IRCAM3 on UKIRT, and show a host of objects not apparent in previous images (cf. Knapen et al. 1995, ApJ, 443, L73). We have also obtained H- and K-band spectra with CGS4 on UKIRT of the nucleus and two of the most prominent circumnuclear star formation regions of M100. An analysis of the near-infrared colours and line ratios allows us to place new constraints on the ages, dust extinction, and stellar populations of these regions.

    The effect of local and large scale environment on star formation histories in galaxies
    The environment of galaxies plays a key role in their evolution. The availability of large extragalactic surveys makes it possible to place a galaxy not only in its immediate environment, but also in its position within the large-scale structure of the universe. Within this context, we investigate how the local environment influences the star

    The role of AGN feedback on the evolution of dwarf galaxies from cosmological simulations: SMBHs suppress star formation in low-mass galaxies
    Recent observational studies suggest that feedback from active galactic nuclei (AGNs) may play an important role in the formation and evolution of low-mass dwarf galaxies, an issue that has received little attention from a theoretical perspective. We investigate this using two sets of 12 cosmological magneto-hydrodynamical simulations of the

    Using gas kinematics to measure resonant structures in disc galaxies: the interaction of M51 with NGC 5195
    Interstellar gas offers advantages when quantifying the structure of the resonances in disc galaxies. The gas is concentrated close to the disc mid-plane, making it easier to determine its in-plane velocity components, and it offers sharp emission lines for good velocity resolution. These properties are shared by atomic, molecular, and ionized gas
