We report contributions to cosmic infrared background (CIB) intensities originating from known galaxies and their faint companions at submillimeter wavelengths. Using the publicly available UltraVISTA catalog and maps at 250, 350, and 500 μm from the Herschel Multi-tiered Extragalactic Survey, we perform a novel measurement that exploits the fact

We have observed a sample of 12 interacting galaxies using the Fabry-Perot interferometer GHαFaS (Galaxy Hα Fabry-Perot system) on the 4.2m William Herschel Telescope (WHT) at the Observatorio del Roque de los Muchachos, La Palma, deriving maps in Hα surface brightness, velocity and velocity dispersion. We extracted the physical parameters (Hα

Accretion of gas from the cosmic web to galaxy halos and ultimately their disks is a prediction of modern cosmological models but is rarely observed directly or at the full rate expected from star formation. Here we illustrate possible large-scale cosmic HI accretion onto the nearby dwarf starburst galaxy IC10, observed with the VLA and GBT. We

Recently, it has been found that classifying early-type galaxies into fast and slow rotators based on their kinematics is more in accordance with their physical properties than the traditional morphological classification of S0 and ellipticals. In the framework of the kinematic classification, observations by the ATLAS3D Project have found that

We have observed the interacting galaxies system, the Antennae, using the Fabry-Perot interferometer GHαFaS on the 4.2m William Herschel Telescope at the Observatorio del Roque de los Muchachos, La Palma, deriving the Hα surface brightness, velocity and velocity dispersion maps, and extracting key physical parameters (mean electron density, mass

We present precision radial velocities and stellar population parameters for 77 star clusters in the Local Group galaxy M33. Our Gran Telescopio de Canarias and William Herschel Telescope observations sample both young, massive clusters and known/candidate globular clusters (GCs), spanning ages ˜106-1010 yr, and metallicities, [M/H] ˜ -1.7 to solar
