Interferometric and VLBI (Very Long Baseline Interferometry) observations have shown that water masers are predominantly associated with the innermost portions of the jets/outflows emerging from (proto-)stellar objects. On the other hand, the astrophysical environment traced by the 6.7 GHz (and the associated 12.2 GHz) CH_{3}OH masers is still to be more precisely determined. So far, most high-resolution studies have focused either on CH_{3}OH or on H_{2}O masers and little is known on their connection, wehereas it would be important to study both types of maser emission in the same object. The goal of our long-term project is to perform interferometric and VLBI observations of H_{2}O and CH_3OH masers towards a selected sample of high-mass YSOs where both maser types have been detected. This work presents preliminary results obtained for a few objects of our sample, and discusses possible implications.ELETTRONICOenConference paper10.1017/S17439213050045392-s2.0-63549101352https://www.cambridge.org/core/journals/proceedings-of-the-international-astronomical-union/article/ch3oh-and-h2o-maser-associations-at-very-high-angular-resolution/632FEBDD76D3E6C194DBA21CEAF21C71https://api.elsevier.com/content/abstract/scopus_id/635491013522005IAUS..227..190MFIS/05 - ASTRONOMIA E ASTROFISICA
