SNR G35.6-0.4: the top left and right panels show the GLOSTAR combination images of total and linearly polarized intensity. The red dotted circles represent the two shell-like structures identified at 610 MHz by Paredes et al. (2014), while the black diamond marks the position of the recombination line discovered by Lockman (1989). The TT-plot from GLOSTAR-Effelsberg images and the flux density spectrum are presented in the bottom left and right panels respectively.
