HST/WFC3 UVIS image of the candidate runaway black hole wake RBH-1 at redshift 0.96. The image covers an area of 13.2 arcseconds by 7.7 arcseconds and combines data from the F200LP and F350LP long-pass filters, with a total exposure time of 29,898 seconds. The locations of the two JWST NIRSpec pointings are marked in yellow.
Astronomers Spot First Ever Runaway Supermassive Black Hole
Left: Gaia XP metallicities from Andrae et al. (2023) for TESS Objects of Interest plotted against Galactocentric azimuthal velocity, with the Sun shown for reference. Most TOIs cluster in the thin disk near the Solar neighborhood, while TOI-7019 appears as a clear outlier. Right: Toomre diagram showing Galactocentric azimuthal velocity versus perpendicular velocity, combining radial and vertical components. Dashed curves mark constant total Galactocentric velocity. TOI-7019 falls in a sparsely populated region typically linked to the kinematic thick disk.

Grayscale cutouts of Alaknanda in all JWST NIRCam filters, with a 2 kpc scale bar. Rest-frame wavelengths are marked for each filter, and the F250M and F335M panels highlight [OIII]+Hβ and Hα+[NII] emission after continuum subtraction. The bottom row shows RGB composites from the SW and LW filters, followed by the F277W GALFIT residual and the residual with spiral arm contours. Red ticks mark the possible satellite spheroid at z = 3.973671. All panels are 2.5″ on a side, with north up and east left.

Maps showing the fit with the NFW-ρ² model in the 21 GeV energy bin. Left panel shows the residuals when no halo component is included. Right panel shows the halo model added to the residuals, meaning the observed map with all other model components removed. Both maps use Gaussian smoothing with σ = 1°..
