The following is an example of a generic acknowledgment that includes a reference to a national project, a reference to the funding of the research center and a reference to the funding of competitive groups of the Xunta de Galicia, which can be adapted according to the situation:

This work has received financial support from the Agencia Estatal de Investigación (Spain) (REFERENCIA DEL PROYECTO / AEI / CÓDIGO AXUDA), the Xunta de Galicia - Consellería de Cultura, Educación, Formación Profesional e Universidades (Centro de investigación de Galicia accreditation 2019-2022 ED431G-2019/04 and Reference Competitive Group accreditation 2021-2024, CÓDIGO AXUDA) and the European Union (European Regional Development Fund - ERDF)

Advertising regulations may change depending on the funding call, so the corresponding funding call should be checked in order to comply with the advertising requirements correctly. In all CiTIUS staff publications, the ERDF support must be expressly mentioned, as this is required by the granting of support to the Centre.
