    The effects of environment on galaxies' dynamical structures: From simulations to observations
    We studied the effects of cluster environments on galactic structures by using the TNG50 cosmological simulation and observed galaxies in the Fornax cluster. We...

    The effects of galaxy formation on the matter power spectrum: a challenge for precision cosmology
    Upcoming weak lensing surveys, such as LSST, EUCLID and WFIRST, aim to measure the matter power spectrum with unprecedented accuracy. In order to fully exploit...

    The effects of seeing on Sèrsic profiles
    The effects of seeing on the parameters of the Sèrsic profile are studied in an analytical form using a Gaussian point spread function. The surface brightness...

    The effects of seeing on Sérsic profiles - II. The Moffat PSF
    The effects of seeing on Sérsic r1/n profile parameters are extensively studied using a Moffat function. This analytical approximation to the point spread...

    The effects of spatial resolution on integral field spectrograph surveys at different redshifts - The CALIFA perspective
    Context. Over the past decade, 3D optical spectroscopy has become the preferred tool for understanding the properties of galaxies and is now increasingly used...

    The Einstein Cross: Constraint on Dark Matter from Stellar Dynamics and Gravitational Lensing
    We present two-dimensional line-of-sight stellar kinematics of the lens galaxy in the Einstein Cross, obtained with the GEMINI 8 m telescope, using the GMOS...

    The ELAIS deep X-ray survey - I. Chandra source catalogue and first results
    We present an analysis of two deep (75 ks) Chandra observations of the European Large Area Infrared Space Observatory (ISO) Survey (ELAIS) fields N1 and N2 as...

    The electron temperatures of SDSS high-metallicity giant extragalactic HII regions
    Spectra of high-metallicity [12+log(O/H) >~ 8.2] HII regions, where oxygen auroral lines are measurable in both the O+ and O++ zones, have been extracted from...

    The elemental abundance of quiescent galaxies in the LEGA-C survey: the (non-)evolution of [α/Fe] from z = 0.75 to z = 0
    We measure the [α/Fe] abundances for 183 quiescent galaxies at z = 0.60-0.75 with stellar masses ranging 10.4 ≤ log 10(M */M ⊙) ≤ 11.6 selected from the Large...
