SPHEREx confirms predictions for artificial satellite trail pollution in Low Earth Orbit
Alejandro S. Borlaff, Pamela M. Marcum, Steve B. Howell +3
The number of artificial satellites in Low Earth Orbit (LEO) is increasing at an exponential rate since 2019. Satellites are visible to both ground and space telescopes, and their…
AGN Feedback and the Development of Dusty Multiphase Gas in X-ray Emitting Elliptical Galaxies
Pasquale Temi, Francesco Ubertosi, Fabrizio Brighenti +9
This paper investigates the physical and kinematic properties of dust-rich regions in a small sample of group-centered elliptical galaxies, emphasizing their connection with the ho…
The Curious Case of Centaurus A II: On the Subject of the Quenched satellites
Sachi Weerasooriya, Mia Sauda Bovill, Matthew A. Taylor +6
The satellite system of Centaurus A presents a curious cosmological puzzle: while the global population is consistent with theoretical expectations, its inner regions (d<150 kpc) e…
Truncations in the X-ray Halos of Early-Type Galaxies as a Tracer of Feedback and Mergers
Nushkia Chamba, Pamela M. Marcum, Alejandro S. Borlaff +2
The morphology of X-ray halos in early-type galaxies depends on key structure assembly processes such as feedback and mergers. However, the signatures of these processes are diffic…
