Optical Photometric Monitoring of the Blazar OT 355 and Local Standard Stars' Calibration
R. Bachev, Tushar Tripathi, Alok C. Gupta +11
OT 355 (4FGL J1734.3 + 3858) is a relatively rarely studied but highly variable, moderate-redshift (z = 0.975) flat-spectrum radio quasar (blazar). With this work, we aim to study…
