Radio Turnover Could Probe Little Red Dot Gas
A proposed free-free emission test could constrain ionized gas size and electron column.
Summary
A proposed free-free emission test could constrain ionized gas size and electron column.
Models predict that free-free self-absorption should create a radio spectral turnover tied to electron column density and the size of an ionized region. The authors propose ALMA and ngVLA observations; this is an observational test, not a reported detection.
Why it matters
A proposed free-free emission test could constrain ionized gas size and electron column.
