    The Recent Stellar Archeology of M31—The Nearest Red Disk Galaxy
    We examine the star-forming history of the M31 disk during the past few hundred Myr. The luminosity functions (LFs) of main-sequence stars at distances R GC >...

    The red giant branches of Galactic globular clusters in the [(V-I)0,MV] plane: metallicity indices and morphology
    The purpose of this study is to carry out a thorough investigation of the changes in morphology of the red giant branch (RGB) of Galactic globular clusters (GGC...

    The redshift and broad-band spectral energy distribution of NRAO 150
    Context. NRAO 150 is one of the brightest radio and mm AGN sources in the northern sky, and is an interesting source to study extreme relativistic jet phenomena...

    The Redshift Distribution of Flat-Spectrum Radio Sources
    The redshift distribution of flat-spectrum radio sources with 5 GHz flux densities S5>~5 mJy is a key component in using current radio lens surveys to probe the...

    The redshift evolution of galactic bar pattern speed in TNG50
    In this paper, the redshift evolution of the galactic bar properties, like the bar length, pattern speed, and bar fraction, has been investigated for simulated...

    The redshift evolution of major merger triggering of luminous AGNs: a slight enhancement at z ˜ 2
    Active galactic nuclei (AGNs), particularly the most luminous AGNs, are commonly assumed to be triggered through major mergers; however, observational evidence...

    The Redshift of the BL Lac Object TXS 0506+056
    The bright BL Lac object TXS 0506+056 is the most likely counterpart of the IceCube neutrino event EHE 170922A. The lack of this redshift prevents a...

    The relation between bar formation, galaxy luminosity, and environment.
    We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy...

    The relation between mergers and AGN activity. Results from radio galaxy and luminous infrared galaxy studies
    There is morphological evidence that the activity in powerful radio galaxies could be triggered by mergers and galaxy interactions. However, nothing is known...
