Lensing in the Blue IV: The First Weak Gravitational Lensing Maps from the Stratosphere

Sayan Saha, Maya Amit, Jacqueline E. McCleary +42

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 th…

Multi-epoch Detection of an Ultra-fast Inflow in ESP 39607: Evidence for an Accretion Cascade

Alessandro Peca, Michael J. Koss, Roberto Serafinelli +10

We present simultaneous XRISM, XMM-Newton, and NuSTAR observations of ESP 39607, a Seyfert 2 galaxy at . XRISM/Resolve reveals two absorption features near 4.7 and 4.9 k…

AGN-DB: A Unified Multi-Wavelength Database of Active Galactic Nuclei

Alessandro Peca, Nico Cappelluti, C. Megan Urry +29

We present the Active Galactic Nuclei Database (AGN-DB), a comprehensive, multi-wavelength catalog compiled from more than 100 publicly available AGN catalogs and samples released…

Multi-sensor fusion for fine-guidance and milliarcsecond-level attitude estimation of balloon-borne telescope

Philippe Voyer, Maya Amit, Steven J. Benton +44

Balloon-borne telescopes rely on fine-guidance systems to achieve milliarcsecond image stability despite residual disturbances from the balloon environment. In these systems, the F…

Lensing-Reconstructed Dark Matter-Intracluster Medium Coherence as a Probe of Cluster Dynamical State: Application to HSTFF, RELICS, and CLASH Clusters

Giulia Cerini, Sayan Saha, Jacqueline McCleary +13

We present the first application of Fourier-space coherence analysis between the lensing-reconstructed projected mass distribution and the X-ray-emitting intracluster medium to a s…

Lensing in the Blue III: Weak Lensing Shape Catalogs of 30 Merging Galaxy Clusters

Sayan Saha, Jacqueline E. McCleary, Spencer W. Everett +38

We present the weak gravitational lensing dataset from the Super-pressure Balloon-Borne Imaging Telescope (SuperBIT), which imaged 30 galaxy clusters during its 45 night flight in…
