Radio and Optical Properties of the blazar PKS 1614+051 at z=3.21
Yu. V. Sotnikova, A. G. Mikhailov, A. E. Volvach +21
We present a study of the radio and optical properties of the high-frequency peaker (HFP) blazar PKS 1614+051 at based on the data covering the time period of 1997-2024. T…
Monitoring of DDO68 'Northern Ring' SF regions during years 2016-2023
S. A. Pustilnik, Y. A. Perepelitsyna, A. S. Vinokurov +6
DDO68 is a star-forming (SF) dwarf galaxy residing in a nearby void. Its gas metallicity is among the lowest known in the local Universe, with parameter 12+log(O/H) in the range of…
Long-term optical spectral monitoring of a changing-look AGN NGC 3516 I: Continuum and broad-line flux variability
A. I. Shapovalova, L. C. Popovic, V. L. Afanasiev +11
Here we present the long-term optical spectral monitoring of a changing-look active galactic nuclei (AGN) NGC 3516 that covers 22 years (from 1996 to 2018). We explore a variabilit…
Long-term optical spectral monitoring of NGC 7469
Alla I. Shapovalova, L. C. Popović, V. H. Chavushyan +11
We present the results of the long-term (20-year period, from 1996 to 2015) optical spectral monitoring of the Seyfert 1 galaxy NGC 7469. The variation in the light-curves of the b…
