Steady-State Feedback: High-Resolution Radio Survey Detects Supermassive Black Hole Activity in Dormant Galaxies

Summary Glossary • Discovery: Compact radio emission detected in nearly 25% of nearby galaxies previously categorized as dormant. • Mechanism: Weakly accreting supermassive black holes (SMBHs) effectively hiding from optical and standard X-ray surveys. • Technology: Utilized the e-MERLIN radio array (UK) to achieve parsec-scale resolution. • Implication: Low-level accretion may be the dominant
