Using Cepheids to determine the galactic abundance gradient I. The solar neighbourhood
S. M. Andrievsky, V. V. Kovtyukh, R. E. Luck +7
A number of studies of abundance gradients in the galactic disk have been performed in recent years. The results obtained are rather disparate: from no detectable gradient to a rat…
What is the manifestation of a "quasar" at z > 10^{10} ?
V. K. Dubrovich
The process of forming an image of a cosmological point source (CPS) in condition of high optical depth is considered accounting for all types of interactions. It is shown that the…
Observations of Stellar Objects at a Shell Boundary in the Star-Forming Complex in the Galaxy IC1613
T. A. Lozinskaya, V. P. Arkhipova, A. V. Moiseev +1
The single region of ongoing star formation in the galaxy IC 1613 has been observed in order to reveal the nature of compact emission-line objects at the edges of two shells in the…
The KPNO International Spectroscopic Survey. III. [O III]-selected Survey List
John J. Salzer, Caryl Gronwall, Vicki L. Sarajedini +8
The KPNO International Spectroscopic Survey (KISS) is an objective-prism survey for extragalactic emission-line objects. It combines many of the features of previous slitless spect…
Photometric study of radio galaxies in RATAN--600 "Cold" survey
O. V. Verkhodanov, Yu. N. Parijskij, N. S. Soboleva +4
About 100 steep spectrum radio sources from the RATAN--600 RC catalog were mapped by the VLA and identified with optical objects down to 24--25 in the R band using the 6 m…
Decametric AGNs: FIRST and NVSS maps and radio spectra
Oleg V. Verkhodanov, Natalia V. Verkhodanova, Heinz Andernach
Radio sources from the decametric UTR--2 catalog were cross-identified with other radio catalogs at higher frequencies. We used the CATS database to extract all sources within the…
