The Super-Pressure Balloon-borne Imaging Telescope (SuperBIT) completed its science flight in April 2023, obtaining imaging data for 30 galaxy clusters. In this work, we present the first weak-lensing convergence maps from these observations, using six clusters selected from the 30 targets. We construct background-galaxy catalogs using SuperBIT's three-band photometry and a color-color-based method to separate foreground and background galaxies, and use the calibrated galaxy shapes presented in Lensing in the Blue III to reconstruct the weak-lensing convergence field using Kaiser-Squires inversion. We compare the convergence signal-to-noise maps for the six clusters with independent tracers, including X-ray emission and red-sequence cluster-member number-density maps. These results demonstrate the first successful weak-lensing mass mapping with imaging from a sub-orbital astronomical observatory.
Understanding the properties of the first generation of galaxies is an ongoing challenge in observational astrophysics. James Webb Space Telescope deep-field observations have led to the identification of large numbers of galaxies within the Epoch of Reionization (EoR); however, it remains observationally challenging t...

The extreme brightness of high-z strongly lensed galaxies detected by Planck surveys, thanks to their exceptionally large gravitational magnifications, offers a unique opportunity to investigate their structure and kinematics during their active star formation phase in extraordinary detail. As a step in this direction,...

Strong gravitational lensing provides a unique tool of studying intrinsically faint high-redshift active galactic nuclei (AGN). In particular, low-luminosity AGN (LLAGN) can probe black-hole growth in low-mass galaxies that current X-ray surveys cannot otherwise access. We investigate the nature and physical properties...

We study the physical properties of high-redshift galaxies, taking advantage of the magnification offered by strong gravitational lensing. Our approach involves the analysis of high-resolution data from leading observatories, including the Atacama Large Millimeter/submillimeter Array (ALMA) to probe the cold interstell...

Galaxies at redshift z~2-6 exhibit prominent star-forming regions (clumps). Characterisation of these galactic structures requires both high sensitivity and spatial resolution of ~100 pc or less. Currently, these spatial scales are achievable only with the aid of strong gravitational lensing. However, lensing introdu...

The transverse motion of a gravitational potential induces frequency shifts in photons propagating through it, giving rise to the moving-lens effect and providing a probe of transverse peculiar velocities. Statistical evidence for this effect has recently been reported using cross-correlations between cosmic microwave...
