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…
Revisiting Galaxy Cluster Scaling Relations through Dark Matter-Gas Coherence: Scatter Dependence on Dynamical State
Giulia Cerini, Elena Bellomi, Nico Cappelluti +4
Galaxy clusters, the most massive, dark-matter-dominated, and most recently assembled structures in the Universe, are key tools for probing cosmology. However, uncertainties in sca…
NuSTAR Detection of an Absorption Feature in ESP 39607: Evidence for an Ultra-Fast Inflow?
Alessandro Peca, Michael J. Koss, Roberto Serafinelli +4
We report the serendipitous discovery of an absorption feature at 4.8 keV in the NuSTAR spectra of ESP 39607, a Seyfert 2 galaxy at , observed in May 2023 and August 202…
Tracing High-z Galaxies in X-rays with JWST and Chandra
A. Kaminsky, N. Cappelluti, G. Hasinger +14
We leverage JWST data from the COSMOS-Web Survey in order to provide updated measurements on the auto-power spectrum of the now resolved Cosmic Infrared Background (CIB) and its co…
