Improving model-satellite comparisons of sea ice melt onset with a satellite simulator [PDF]
The Cryosphere, 2022 Seasonal transitions in Arctic sea ice, such as the melt onset, have been found to be useful metrics for evaluating sea ice in climate models against observations. However, comparisons of melt onset dates between climate models and satellite observations

Dark skies and bright satellites [PDF]
Science, 2020 Most ground-based observatories require a dark night sky to uncover answers to some of the most fundamental questions about the nature of our Universe. However, a number of companies and governments are in various stages of planning or deploying bright satellites in low-Earth orbit (or LEOsats) in greater numbers than ever before.

Milky Way Satellites Shining Bright in Gravitational Waves [PDF]
The Astrophysical Journal Letters, 2020 Abstract The population of Milky Way satellite galaxies is of great interest for cosmology, fundamental physics, and astrophysics. They represent the faint end of the galaxy luminosity function, are the most dark-matter-dominated objects in the local universe, and contain the oldest and most metal-poor stellar populations. Recent surveys
