Satellite Constellations & Astronomy: What is the problem? What are we doing about it? In recent years, large satellite constellations have been launched into low-Earth orbit to provide low-latency, global communication coverage. As a result, the number of satellites in orbit has surged from approximately 2,500 to over 10,000, raising...

Optical spectroscopy and imaging of blazars for the Cherenkov Telescope Array Observatory Blazars are the brightest persistent sources in the high-energy and very-high-energy (VHE) gamma-ray sky. Because their UV/optical radiation is often dominated by non-thermal, and, in the case of BL Lacs, featureless continuum radiation, the determination of their redshift...
