Negative Search for a Counterpart to the Gamma-Ray Repeater Source 0525-66
Abstract
Radio continuum, near-infrared [Fe II], H2, and Brγ, and optical Hα images of the supernova remnant N49 in the LMC, show a filamentary shell structure, characteristic of remnants in the adolescent or middle-aged phase of their evolution. No evidence is found in these images for any feature associated with the soft γ-ray repeater 0525-66 projected within the outline of this SNR. The nature of an X-ray hot spot located near the position of the γ-ray source remains uncertain, but the lack of emission at other wavelengths places significant limits on any nonthermal contribution to its radiation.
