Optical Spectra of Candidate International Celestial Reference Frame (ICRF) Flat-Spectrum Radio Sources. III
O. Titov, T. Pursimo, H. M. Johnston +4
In extending our spectroscopic program, which targets sources drawn from the International Celestial Reference Frame (ICRF) Catalog, we have obtained spectra for about 160 compact…
Optical Spectra of Flat-Spectrum ICRF Radio Sources
Oleg Titov, Laura M. Stanford, Helen M. Johnston +5
Continuing our program of spectroscopic observations of ICRF sources, we present redshifts for 120 quasars and radio galaxies. Data were obtained with five telescopes: the 3.58m ES…
Determination of Redshifts for Selected IVS Sources. I
Kirill Maslennikov, Alexandra Boldycheva, Zinovy Malkin +1
From observations with the 6-m BTA telescope at SAO RAS, we have determined spectroscopic redshifts of seven optical objects whose coordinates coincide with those of radio sources…
