Skykatana: a scalable framework to construct sky masks for the Vera Rubin Observatory and large astronomical surveys
Claudio Lopez, Emilio Donoso, Mariano Javier de L. Dominguez Romero
Modern wide-field surveys require robust spatial masks to excise bright-star halos, bleed trails, poor-quality regions, and user-defined geometry at scale. We present Skykatana, an…

An improved formalism for measuring the dark matter subhalos mass by its gravitational wake
M. E. Mosquera, K. J. Fushimi, M. J. de L. Domínguez Romero
We reexamined the framework used to determine the dark matter mass of a subhalo using the gravitational effects of its passage upon the stellar halo of a host. In particular, we ai…
