Roman Will Count Black Holes by Their Messiest Meals
Simulations suggest the telescope could find up to 100 stellar tidal-disruption events each year, including in the early universe.
Summary
Simulations suggest the telescope could find up to 100 stellar tidal-disruption events each year, including in the early universe.
A new forecast says Roman's wide, repeated infrared survey can catch stars being torn apart by otherwise faint supermassive black holes, including systems seen as far back as 11 billion years. The expected sample could help distinguish early black-hole growth routes. The count is a mission forecast before launch, not an observed catalog.
Why it matters
Simulations suggest the telescope could find up to 100 stellar tidal-disruption events each year, including in the early universe.
Limits and context
- The count is a mission forecast before launch, not an observed catalog.
