Markarian 501
Mrk 501 has a redshift z = 0.034 (∼ 456 Mly ∼ 140 Mpc) and
R. A. = 16h 53m 52.2s, Dec.= +39° 45’ 37”. It has been monitored in radio (Richards et al. 2011), optical (Smith et al.
2009), X-ray (Abdo et al. 2011a), and γ-ray (Dorner et al.
2017). This object has several periodicities reported (Bhatta
2019). Recently Magallanes-Guijón & S. Mendoza (2022) have reported a periodicity ∼ 224 days.
