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…

Detection of a dark matter subhalo in the strongly lensed system PJ011646

Aristeidis Amvrosiadis, James W. Nightingale, Qiuhan He +12

We present a strong lensing analysis of the system PJ011646 using high-resolution (0.1 arcsec) Atacama Large Millimeter/submillimeter Array (ALMA) dust-continuum observations…

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…

Measuring the Stellar-to-Halo Mass Relation at Solar masses, using forthcoming space-based imaging of galaxy-galaxy strong lenses

Kaihao Wang, Xiaoyue Cao, Ran Li +11

The stellar-to-halo mass relation (SHMR) is central to understanding the co-evolution of galaxies and their host dark matter haloes, yet it remains weakly constrained for dwarf gal…

Probing Dark Matter Substructures with Free-Form Modelling: A Case Study of the `Jackpot' Strong Lens

Xiaoyue Cao, Ran Li, James W. Nightingale +12

Characterising the population and internal structure of sub-galactic halos is critical for constraining the nature of dark matter. These halos can be detected near galaxies that ac…
