Radiation damage to the Hubble Space Telescope has been several years out of phase with the Solar cycle
Gavin Leroy, Juan Paolo Lorenzo Gerardo Barrios, Maximilian von Wietersheim-Kramsta +8
As well as obtaining beautiful images of the Universe, the Hubble Space Telescope's CCD detectors are sensitive radiation dosimeters that have been monitored in Low Earth Orbit for…
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…
COSMOS-Web: Galaxy Size and Surface Brightness Evolution at Rest-Frame 1.22 m Since
Si-Yue Yu, Andreas L. Faisst, Taotao Fang +7
We present the evolution of galaxy size and surface brightness in the rest-frame band (1.22 m), tracing the stellar mass distribution, over , using a sam…
COSMOS-Web galaxy groups: Evolution of red sequence and quiescent galaxy fraction
Greta Toni, Matteo Maturi, Gianluca Castignani +33
We investigate the redshift and group richness dependence of the quiescent fraction and red-sequence (RS) parameters in COSMOS galaxy groups from z=0 to z=3.7. We analyzed the deep…
SLICE -- Combining Strong Lensing and X-ray in AC 114. Further Insights into the Merger Scenario
Marceau Limousin, Benjamin Beauchesne, Keren Sharon +14
AC114 is a historically significant galaxy cluster, being one of the first strong lensing clusters detected from the ground in the early 1990s, prior to the launch of the HST. Desp…
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…
