  Recent JWST/NIRCam imaging taken for the ultra-deep UNCOVER program reveals a
very red dropout object at $z_{\mathrm{phot}}\simeq7.6$, triply imaged by the
galaxy cluster Abell 2744 ($z_{\mathrm{d}}=0.308$). All three images are very
compact, i.e. unresolved, with a de-lensed size upper-limit of
$r_{e}\lesssim35$ pc. The images have apparent magnitudes of
$m_{\mathrm{F444W}}\sim25-26$ AB, and the magnification-corrected absolute UV
magnitude of the source is $M_{\mathrm{UV},1450}=-16.81\pm0.09$. From the sum
of observed fluxes and from a spectral energy distribution (SED) analysis, we
obtain estimates of the bolometric luminosities of the source of
$L_{\mathrm{bol}}\gtrsim10^{43} \frac{\mathrm{erg}}{\mathrm{s}}$ and
$L_{\mathrm{bol}}\sim10^{44}-10^{46} \frac{\mathrm{erg}}{\mathrm{s}}$,
respectively. Based on its compact, point-like appearance, its position in
color-color space and the SED analysis, we tentatively conclude that this
object is a UV-faint dust-obscured quasar-like object, i.e. an active galactic
nucleus (AGN) at high redshift. We also discuss other alternative origins for
the object's emission features, including a massive star cluster, Population
III, supermassive, or dark stars, or a direct-collapse black hole. Although
populations of red galaxies at similar photometric redshifts have been detected
with JWST, this object is unique in that its high-redshift nature is
corroborated geometrically by lensing, that it is unresolved despite being
magnified -- and thus intrinsically even more compact -- and that it occupies
notably distinct regions in both size-luminosity and color-color space. Planned
UNCOVER JWST/NIRSpec observations, scheduled in Cycle 1, will enable a more
detailed analysis of this object.
