    A fast bar in the post-interaction galaxy NGC 1023
    We measured the bar pattern speed, Ωp , of the SB0 galaxy NGC 1023 using the Tremaine-Weinberg method with stellar-absorption slit spectroscopy. The morphology...

    A fast, very-high-energy γ-ray flare from BL Lacertae during a period of multi-wavelength activity in June 2015
    The mechanisms producing fast variability of the γ-ray emission in active galactic nuclei (AGNs) are under debate. The MAGIC telescopes detected a fast, very...

    A feather on the hat: tracing the giant stellar stream around the Sombrero galaxy
    Recent evidence of extremely metal-rich stars found in the Sombrero galaxy (M104) halo suggests that this galaxy has undergone a recent major merger with a...

    A few StePS forward in unveiling the complexity of galaxy evolution: light-weighted stellar ages of intermediate-redshift galaxies with WEAVE
    Context. The upcoming new generation of optical spectrographs on four-meter-class telescopes, with their huge multiplexing capabilities, excellent spectral...

    A First Glimpse Into the Far-IR Properties of High-z UV-selected galaxies: Herschel/PACS Observations of z ~ 3 LBGs
    We present first insights into the far-IR properties for a sample of IRAC and MIPS 24 μm detected Lyman break galaxies (LBGs) at z ~ 3, as derived from...

    A fundamental plane for field star-forming galaxies
    Context. Star formation rate (SFR), metallicity, and stellar mass are among the most important parameters of star-forming (SF) galaxies characterizing their...

    A galaxy-driven model of type Ia supernova luminosity variations
    Type Ia supernovae (SNe Ia) are used as standardizable candles to measure cosmological distances, but differences remain in their corrected luminosities which...

    A geometric distance to the supermassive black Hole of NGC 3783
    The angular size of the broad line region (BLR) of the nearby active galactic nucleus NGC 3783 has been spatially resolved by recent observations with VLTI...

    A giant radio galaxy with three cycles of episodic jet activity from LoTSS DR2
    The excellent sensitivity and optimum resolution of LoTSS DR2 at 144 MHz has enabled us to discover a giant radio galaxy (J1225+4011) with three distinct...
