    First Bounds on the Very High Energy γ-Ray Emission from Arp 220
    Using the Major Atmospheric Gamma Imaging Cerenkov Telescope (MAGIC), we have observed the nearest ultraluminous infrared galaxy, Arp 220, for about 15 hr. No...

    First Confirmed Detection of a Bipolar Molecular Outflow from a Young Brown Dwarf
    Studying the earliest stages in the birth of stars is crucial for understanding how they form. Brown dwarfs with masses between that of stars and planets are...

    First Detection of Molecular Gas in the Giant Low Surface Brightness Galaxy Malin 1
    After over three decades of unsuccessful attempts, we report the first detection of molecular gas emission in Malin 1, the largest spiral galaxy observed to...

    First Detection of Sign-reversed Linear Polarization from the Forbidden [O I] 630.03 nm Line
    We report on the detection of linear polarization of the forbidden [O i] 630.03 nm spectral line. The observations were carried out in the broader context of...

    First Direct Evidence for Keplerian Rotation in Quasar Inner Broad-line Regions
    We introduce a novel method to derive rotation curves with light-day spatial resolution of the inner regions of lensed quasars. We aim to probe the kinematics...

    First Evidence of Enhanced Recombination in Astrophysical Environments and the Implications for Plasma Diagnostics
    We report the first unambiguous observational evidence of Rydberg Enhanced Recombination (RER), a potentially important recombination mechanism that has...

    First Look at z > 1 Bars in the Rest-frame Near-infrared with JWST Early CEERS Imaging
    Stellar bars are key drivers of secular evolution in galaxies and can be effectively studied using rest-frame near-infrared (NIR) images, which trace the...

    First Metis Detection of the Helium D<SUB>3</SUB> Line Polarization in a Large Eruptive Prominence
    Metis on board Solar Orbiter is the space coronagraph developed by an Italian-German-Czech consortium. It is capable of observing solar corona and various...

    First NuSTAR Observations of Mrk 501 within a Radio to TeV Multi-Instrument Campaign
    We report on simultaneous broadband observations of the TeV-emitting blazar Markarian 501 between 2013 April 1 and August 10, including the first detailed...
