Abstract: BL Lac objects are low-power active nuclei exhibiting a variety of peculiar properties caused by the presence of a relativistic jet and orientation effects. Since the jet is closely aligned with the line of sight, it is very difficult to observe unless the angular resolution is high. At millimeter wavelength in particular, until the advent of ALMA, information on the jet emission was lacking from the previous facilities. Here we report our preliminary results on the millimeter emission of PKS 0521-365, one of the most interesting BL Lac objects of the southern sky, using ALMA multifrequency archival data.
