cds-question@unistra.frgalaxiesvariable-starsinfrared-photometryvisible-astronomyphotometryWe present the discovery of 1847 Mira candidates in the Local Group galaxy M33 using a novel semi-parametric periodogram technique coupled with a random forest classifier. The algorithms were applied to ~2.4*10^5^ I-band light curves previously obtained by the M33 Synoptic Stellar Survey. We derive preliminary period-luminosity relations at optical, near-infrared, and mid-infrared wavelengths and compare them to the corresponding relations in the Large Magellanic Cloud.2017AJ....153..170Yhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/153/170CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/152/164 : I-band light curves of OGLE LMC Miras (He+, 2016)J/AJ/149/117 : LMC infrared survey.
