    The Size Evolution of Galaxies since z~3: Combining SDSS, GEMS, and FIRES
    We present the evolution of the luminosity-size and stellar mass-size relations of luminous (LV>~3.4×1010 h-270 Lsolar) and massive (M*>~3×1010 h-270 Msolar)...

    The size function of massive satellites from the R<SUB>e</SUB>-R<SUB>h</SUB> and M<SUB>star</SUB>-M<SUB>h</SUB> relations: constraining the role of environment
    In previous work, we showed that a semi-empirical model in which galaxies in host dark matter haloes are assigned stellar masses via a stellar mass-halo mass...

    The size-luminosity relation of local active galactic nuclei from interferometric observations of the broad-line region
    By using the GRAVITY instrument with the near-infrared (NIR) Very Large Telescope Interferometer (VLTI), the structure of the broad (emission-)line region (BLR)...

    The Sloan Digital Sky Survey extended point spread functions
    A robust and extended characterization of the point spread function (PSF) is crucial to extract the photometric information produced by deep imaging surveys...

    The Soft X-ray and Narrow-line Emission of Mrk 573 on Kiloparsec Scales
    We present a study of the circumnuclear region of the nearby Seyfert galaxy Mrk 573 using Chandra, XMM-Newton, and Hubble Space Telescope (HST) data. We have...

    The Space Density of Luminous Dusty Star-forming Galaxies at z > 4: SCUBA-2 and LABOCA Imaging of Ultrared Galaxies from Herschel-ATLAS
    Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at z > 4, most of them significantly amplified by gravitational lensing. Here...

    The Spatial and Age Distribution of Stellar Populations in DDO 190
    The spatial distribution of stellar populations, the star formation history, and other properties of the dwarf irregular (dIrr) galaxy DDO 190 have been...

    The spatial distribution of coalescing neutron star binaries: implications for gamma-ray bursts
    We find the distribution of coalescence times, birth rates, spatial velocities, and subsequent radial offsets of coalescing neutron stars (NSs) in various...

    The Spatial Distribution of the Far-Infrared Emission in NGC 253
    We study the far-infrared emission properties of the nearby starburst galaxy NGC 253 based on IRAS maps and an ISOPHOT map at 180 μm. Based on the analysis of...
