cds-question@unistra.fractive-galactic-nucleiphotometryvisible-astronomyredshiftedWe present a variability, color and morphology based classifier, designed to identify multiple classes of transients, persistently variable, and non-variable sources, from the Zwicky Transient Facility (ZTF) Data Release 11 (DR11) light curves of extended and point sources. The main motivation to develop this model was to identify active galactic nuclei (AGN) at different redshift ranges to be observed by the 4MOST Chilean AGN/Galaxy Evolution Survey (ChANGES). Still, it serves as a more general time-domain astronomy study. The model uses nine colors computed from CatWISE and PanSTARRS1 (PS1), a morphology score from PS1, and 61 single-band variability features computed from the ZTF DR11 g and r light curves. We trained two versions of the model, one for each ZTF band, since ZTF DR11 treats independently the light curves observed in a particular combination of field, filter, and CCD-quadrant. We used a hierarchical local classifier per parent node approach, where each node was composed of a balanced random forest model. We adopted a 17-class taxonomy, including non-variable stars and galaxies, three transients (SNIa, SN-other, and CV/Nova), five classes of stochastic variables (lowz-AGN, midz-AGN, highz-AGN, Blazar, and YSO), and seven classes of periodic variables (LPV, EA, EB/EW, DSCT, RRL, CEP, and Periodic-other). The macro averaged precision, recall and F1-score are 0.61, 0.75, and 0.62 for the g-band model, and 0.60, 0.74, and 0.61, for the r-band model. When grouping the four AGN classes (lowz-AGN, midz-AGN, highz-AGN, and Blazar) into one single class, its precision, recall, and F1-score are 1.00, 0.95, and 0.97, respectively, for both the $g$ and r bands. This demonstrates the good performance of the model classifying AGN candidates. We applied the model to all the sources in the ZTF/4MOST overlapping sky (-28<=DE<=8.5), avoiding ZTF fields covering the Galactic bulge (|gal_b_|<=9 and gal_l_<=50). This area includes 86576577 light curves in the g-band and 140409824 in the r-band, with 20 or more observations, and with an average magnitude in the corresponding band lower than 20.5. Only 0.73% of the $g$-band light curves and 2.62% of the $r$-band light curves were classified as stochastic, periodic, or transient with high probability (P_init_>=0.9). Even though the metrics obtained for both models are similar, we found that, in general, more reliable results are obtained when using the g-band model. Using the latter, we identified 384242 AGN candidates (including low-, mid-, and high-redshift AGNs and Blazars), 287156 of which have
