Three community‑proposed datasets.
One mission.
A clearer view of the unseen universe.
Some objects in space don’t shine. They don’t glow. They don’t announce themselves.
We find them by watching how stars bend, brighten, and move.
This project proposes three small, high‑impact datasets that—together—enable the Nancy Grace Roman Space Telescope to confirm isolated black holes, neutron stars, and wide‑orbit planets.
What it provides:
A filtered list of rare, long‑duration microlensing events — prime candidates for isolated black holes.
Why it matters:
It turns decades of survey data into a science‑ready discovery list for Roman.
What it provides:
Space‑based parallax measurements — the missing ingredient needed to calculate true lens masses.
Why it matters:
Roman can measure motion.
Spitzer tells us how heavy the object is.
Together, they confirm black holes.
What it provides:
Continuous, high‑cadence light curves that capture the full story of each event.
Why it matters:
Roman never observes a microlensing event without its history.
(Long events = dark remnants)
