    The Effect of Collisional Enhancement of Balmer Lines on the Determination of the Primordial Helium Abundance
    This paper describes a new determination of the primordial helium abundance (YP), based on the abundance analysis of five metal-poor extragalactic H II regions...

    The effect of environment on star forming galaxies at redshift. I. First insight from PACS
    We use deep 70, 100 and 160 μm observations taken with PACS, the Photodetector Array Camera and Spectrometer on board of Herschel, as part of the PACS...

    The effect of environment on the structure of disc galaxies
    We study the influence of environment on the structure of disc galaxies, using imfit to measure the g- and r-band structural parameters of the surface...

    The Effect of Hot Gas in the First-Year Wilkinson Microwave Anisotropy Probe (WMAP) Data
    By cross-correlating templates constructed from the Two Micron All Sky Survey Extended Source Catalog with the first-year data from the Wilkinson Microwave...

    The effect of the environment on the stellar mass-size relationship for present-day galaxies
    In order to study how the environment can influence the relationship between the stellar mass and effective radius for nearby galaxies (z 0.12), we use a mass...

    The effect of the environment-dependent IMF on the formation and metallicities of stars over the cosmic history
    Recent observational and theoretical studies indicate that the stellar initial mass function (IMF) varies systematically with the environment (star formation...

    The effect of tides on the Fornax dwarf spheroidal galaxy
    Estimates of the mass distribution and dark-matter (DM) content of dwarf spheroidal galaxies (dSphs) are usually derived under the assumption that the effect of...

    The effect of tides on the Sculptor dwarf spheroidal galaxy
    Dwarf spheroidal galaxies (dSphs) appear to be some of the most dark matter (DM)-dominated objects in the Universe. Their dynamical masses are commonly derived...
