    Evidence for very massive stars in extremely UV-bright star-forming galaxies at z ∼ 2.2-3.6
    We present a comprehensive analysis of the presence of very massive stars (VMS > 100 M ⊙) in the integrated spectra of 13 UV-bright star-forming galaxies at 2.2...

    Evidence of a Distinct Stellar Population in the Counterrotating Core of NGC 1700
    We find a distinct stellar population in the counterrotating and kinematically decoupled core of the isolated massive elliptical galaxy NGC 1700. Coinciding...

    Evidence of a fast bar in the weakly-interacting galaxy NGC 4264 with MUSE
    We present surface photometry and stellar kinematics of NGC 4264, a barred lenticular galaxy in the region of the Virgo Cluster undergoing a tidal interaction...

    Evidence of Parsec-scale Jets in Low-luminosity Active Galactic Nuclei
    The nuclear radio emission of low-luminosity active galactic nuclei (LLAGNs) is often associated with unresolved cores. In this paper we show that most LLAGNs...

    Evidence of Two Kinematically Different Stellar Systems in NGC 1068
    We have obtained simultaneous two-dimensional spectroscopy of the Ca II triplet lines in the central 24" x 20" of NGC 1068, using an optical fiber system. The...

    Evolution along the sequence of S0 Hubble types induced by dry minor mergers. I. Global bulge-to-disk structural relations
    Context. Recent studies have argued that galaxy mergers are not important drivers for the evolution of S0's, on the basis that mergers cannot preserve the...

    Evolution along the sequence of S0 Hubble types induced by dry minor mergers. II. Bulge-disk coupling in the photometric relations through merger-induced internal secular evolution
    Context. Galaxy mergers are widely discussed as one possible evolution mechanism for lenticular galaxies (S0s), because even minor mergers induce structural...

    Evolution induced by dry minor mergers onto fast-rotator S0 galaxies
    Context. Numerical studies have shown that the properties of the S0 galaxies with kinematics intermediate between fast and slow rotators are difficult to...

    Evolution of active galactic nuclei broad-line region clouds: low- and high-ionization lines
    The formation of quasar broad-line region (BLR) clouds via thermal instability in the presence of Alfvén heating has been discussed by Gonçalves, Jatenco...
