    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 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 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...

    The Emission and Distribution of Dust of the Torus of NGC 1068
    We present observations of NGC 1068 covering the 19.7–53.0 μm wavelength range using FORCAST and HAWC+ on board SOFIA. Using these observations, high-angular...
