Notes. Periodicity candidates with a local significance ≥ 2σ, sorted from largest to smallest. We use the 4FGL-DR2 catalog for the coordinate and redshift. The redshift of PG 1553+113 was taken from Johnson et al. (2019) and Dorigo Jones et al. (2022). The ‘*’ denotes blazars without previous evidence of periodicity in γ-rays.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
