# A Deep VLA Search for a Persistent Radio Counterpart to the One-off FRB 20250316A

Tao An, Ailing Wang, Yu-Chen Huang et al., 2025. _The Astrophysical Journal Letters 991(1), L20_.

FRB 20250316A, detected by CHIME on 16 March 2025 at about 40 Mpc with a fluence of 1.7 kJy ms, has no persistent radio source to a 3-sigma limit of 8.4 microjansky at 15 GHz, more than three orders of magnitude below the compact sources around well-studied repeaters.

## What it's used for here

The deepest persistent-source limit for a non-repeater; disfavours bright magnetar nebulae for it.
