    Internal turbulence, viriality, and density bounding of the most luminous H II regions in the spiral galaxy M 100
    We present TAURUS Fabry-Perot velocity data in Hα emission of the disc of the grand design spiral M 100 (NGC 4321). We have studied the emission spectra of the...

    Intracluster light at the Frontier - II. The Frontier Fields Clusters
    Multiwavelength deep observations are a key tool to understand the origin of the diffuse light in clusters of galaxies: the intracluster light (ICL). For this...

    Intracluster Light at the Frontier: A2744
    The ultra-deep multiwavelength Hubble Space Telescope Frontier Fields coverage of the Abell Cluster 2744 is used to derive the stellar population properties of...

    Intracluster light in the Virgo cluster: large scale distribution
    Aims: The intracluster light (ICL) is a faint diffuse stellar component of clusters made of stars that are not bound to individual galaxies. We have carried out...

    Intracluster light: a luminous tracer for dark matter in clusters of galaxies
    The bulk of stars in galaxy clusters are confined within their constituent galaxies. Those stars do not trace the extended distribution of dark matter well as...

    Intracluster Planetary Nebulae in Virgo: Photometric Selection, Spectroscopic Validation, and Cluster Depth
    We have imaged an empty area of 34×34 arcmin2 1.5d north of the Virgo Cluster core to survey for intracluster planetary nebula (PN) candidates. We have...

    Intracluster Stars in the Virgo Cluster Core
    We have investigated the properties of the diffuse light in the Virgo Cluster core region, based on the detection of intracluster planetary nebulae (PNs) in...

    Intracluster Stellar Population Properties from N-Body Cosmological Simulations. I. Constraints at z = 0
    We use a high-resolution collisionless simulation of a Virgo-like cluster in a ΛCDM cosmology to determine the velocity and clustering properties of the diffuse...

    Intrinsic and observed dual AGN fractions from major mergers
    A suite of 432 collisionless simulations of bound pairs of spiral galaxies with mass ratios 1:1 and 3:1, and global properties consistent with the ΛCDM paradigm...
