Abstract
We present results from 43 GHz (VLBA, six epochs from 2012.2 to 2013.2) and 86 GHz (GMVA,
one epoch in 2012.4) observations toward the basis of the jet in the TeV Blazar Mrk 501. The
43-GHz data analysis reveals a new feature located northeast of the radio core, with a flux density
of several tens of mJy, perpendicularly to the jet axis. The 86-GHz image shows the jet feature
located 0.75 mas southeast of the radio core, which is consistent with previous result. The location
of Gaussian model for 0.75 mas feature does not coincide with those for the jets in the 43-GHz
image, however, a distribution of emission is found. We also discuss the spectral indices of the
core, the northeast feature, and the jet feature between 43 GHz and 86 GHz, which show flat-to-
steep, steep, and flat-to-invert, respectively.
