    Constraints on the evolutionary mechanisms of massive galaxies since z ∼ 1 from their velocity dispersions
    Several authors have reported that the dynamical masses of massive compact galaxies (M* ≳ 1011 M⊙, re ∼ 1 kpc), computed as Mdyn = 5.0 σe2 re/G, are lower than...

    Constraints on the merging channel of massive galaxies since z ˜ 1
    We probe the merging channel of massive galaxies over the z = 0.3-1.3 redshift window by studying close pairs in a sample of 238 galaxies with stellar mass...

    Contemporaneous observations of the radio galaxy NGC 1275 from radio to very high energy γ-rays
    Aims: The radio galaxy NGC 1275, recently identified as a very high energy (VHE, >100 GeV) γ-ray emitter by MAGIC, is one of the few non-blazar active galactic...

    Contribution of a disc component to single-peaked broad lines of active galactic nuclei
    We study the disc emission component hidden in the single-peaked broad emission lines (BELs) of active galactic nuclei. We compare the observed broad lines from...

    Contribution of the disk emission to the broad emission lines in AGNs: Two-component model
    We present an investigation of the structure of the emission line region in a sample of 12 single-peaked Active Galactic Nuclei (AGNs). Using the high...

    Control sample for galaxy pairs: Simulations and Observations
    Several attempts have been made in order to isolate the effect of galaxy interactions by comparing galaxy in pairs with isolated galaxies. However, different...

    Converting Hα Luminosities into Star Formation Rates
    Star formation rates (SFRs) of galaxies are commonly calculated by converting the measured Hα luminosities (LHα) into current SFRs. This conversion is based on...

    Convolutional neural network-reconstructed velocity for kinetic SZ detection
    We report the detection of the kinetic Sunyaev-Zel'dovich (kSZ) effect in galaxy clusters with a 4.9σ significance using the latest 217 GHz Planck map from data...

    Cool Gas and Massive Stars: The Nuclear Ring in M100
    The SAURON integral-field spectrograph was used to observe the central area of the barred spiral galaxy M100 (NGC 4321). M100 contains a nuclear ring of star...
