During the OJ-94 campaign for the blazar OJ 287 the authors have obtained the best ever observed optical light curve for any extragalactic object. They have...
The publication by Lloyd (1984) of new and revised data for a sample of active nuclei brought the number of published observations of 3C 345 up to over 900...
The optical, infrared and radio light curve of OJ 287 during winter 1993 - 94.
The light curves of OJ 287 at UBVRIJHK, 22 and 37 GHz are presented for the 1993/94 observing campaign. Despite the considerable optical and infrared activity...
The Orbit and Companion of PSR J1622-0315: Variable Asymmetry and a Massive Neutron Star
The companion to PSR J1622-0315, one of the most compact known redback millisecond pulsars, shows extremely low irradiation despite its short orbital period. We...
