Our paper has been accepted to ApJ ⬇️ Using mock observations, we show that Roman will detect gaps in streams created by subhalos with masses > 5 x 10^6 Msun in galaxies within 3 MPC, for ~1-hour exposures. Counting these gaps will help constrain the subhalo mass function. arxiv.org/abs/2305.12045

Why waste time throughout the day getting your daily calorie intake when you can do it in just one meal... 😛
