摘要：
We present sensitive, high angular resolution Jansky Very Large Array observations made in 2014 at 1.50 GHz toward the field of Tycho's supernova remnant. We detect a total of 36 compact sources in a field with radius of 13 arcmin. This number is consistent with the expected number of background sources. We use older observations made with the classic Very Large Array to compare with the 2014 observations and search for sources showing large proper motions that could be related to the donor companion of the exploding white dwarf that produced the supernova in 1572. The comparison of the positions for the two sets of observations does not show sources with large proper motions and supports the conclusion that all sources detected are extragalactic and unrelated to the supernova field.
