    First detection of the outer edge of an AGN accretion disc: very fast multiband optical variability of NGC 4395 with GTC/HiPERCAM and LT/IO:O
    We present fast (~200 s sampling) $\it ugriz$ photometry of the low -mass AGN NGC 4395 with the Liverpool Telescope, followed by very fast (3 s sampling) u s, g...

    First detection of VHE gamma-ray emission from TXS 1515-273, study of its X-ray variability and spectral energy distribution
    We report here on the first multiwavelength (MWL) campaign on the blazar TXS 1515-273, undertaken in 2019 and extending from radio to very-high-energy gamma...

    First discovery of an ultra-cool white dwarf benchmark in common proper motion with an M dwarf
    Ultra-cool white dwarfs are among the oldest stellar remnants in the Universe. Their efficient gravitational settling and low effective temperatures are...

    First gravitational-wave burst GW150914: MASTER optical follow-up observations
    The Advanced LIGO observatory recently reported the first direct detection of the gravitational waves (GWs) predicted by Einstein & Sitzungsber. We report on...

    First measurement of the total gravitational quadrupole moment of a black widow companion
    We present the first measurement of the gravitational quadrupole moment of the companion star of a spider pulsar, namely the black widow PSR J2051-0827. To this...

    First performance of the GeMS + GMOS system - 1. Imaging
    During the commissioning of the Gemini MCAO System (GeMS), we had the opportunity to obtain data with the Gemini Multi-Object Spectrograph (GMOS), the most...

    First release of the IPHAS catalogue of new extended planetary nebulae
    We present the first results of our search for new, extended planetary nebulae (PNe) based on careful, systematic, visual scrutiny of the imaging data from the...

    First results of an Hα based search of classical Be stars in the Perseus Arm and beyond
    We investigate a region of the Galactic plane, between 120° ≤ ℓ ≤ 140° and -1° ≤ b ≤ +4°, and uncover a population of moderately reddened (E(B - V) ˜ 1)...
