  bibo_abstract:
  - Recent studies at high redshift have revealed an enigmatic class of little red
    dots (LRDs) with extreme Balmer breaks, stronger than in any stellar atmosphere.
    However, it is unclear whether such objects exist at lower redshift, especially
    given the low number of LRDs reported at z ≲ 2. Here, we report the discovery
    of PAN-BH*-1, an LRD with an extreme Balmer break at z = 1.73, identified from
    JWST/NIRCam pure-parallel imaging taken by the PANORAMIC survey, and confirmed
    by deep VLT/X-Shooter spectroscopy. The rest-optical to near-infrared spectral
    energy distribution of PAN-BH*-1 is consistent with a photospheric continuum with
    effective temperature Teff ≈ 4800 K. The broad Hα emission line shows remarkably
    deep absorption, stronger than previously measured in any LRD. The absorption
    trough spans from −520 to +267 km s−1 with respect to the systemic redshift. The
    presence of blue- and red-shifted absorption suggests complex dynamics of the
    obscuring gas along the line of sight. We speculate that the absorption trough
    can be produced by a thick wind launched from a thick, rotating photospheric disk,
    the latter being the source of the red optical continuum. While the source is
    unresolved in the rest-optical JWST data (reff < 47 pc), the rest-near-UV Hubble
    Space Telescope imaging shows an extended morphology with (formular displayed)
    kpc, which we interpret as a host galaxy with a stellar mass of ∼10^8 M⊙, in line
    with the narrow Hα emission. The discovery of this object at cosmic noon highlights
    the feasibility of systematic searches for extreme LRDs with wide-area facilities
    such as Euclid and Roman.@eng
