Nearby black holes fall into three imaging frequency classes
—
in AstrophysicsWhat the study found Nearby supermassive black hole accretion flows can be grouped into three classes based on whether they become transparent at traditional imaging frequencies, require higher frequencies, or are unlikely to be transparent down to the black hole shadow in the submillimeter band. Why the authors say this matters The study suggests these…

VLBI and Gaia agree on many long-period variable star distances
—
in AstronomyCompare VLBI and Gaia DR3 astrometric measurements of 43 long period variable stars, revealing complementary strengths for determining stellar distances and proper motions across different.
