TOPz: Photometric redshifts using template fitting applied to the GAMA survey
E. Tempel, J. Laur, Z. R. Jones +7
Context. Accurate photometric redshift estimation is crucial for cosmological and galaxy evolution studies, especially with the advent of large-scale photometric surveys. Aims. We…
TOPz: Photometric redshifts for J-PAS
J. Laur, E. Tempel, A. Tamm +30
The importance of photometric galaxy redshift estimation is rapidly increasing with the development of specialised powerful observational facilities. We develop a new photometric r…
The Corona Borealis supercluster: connectivity, collapse, and evolution
Maret Einasto, Rain Kipper, Peeter Tenjes +7
We present a study of the Corona Borealis (CB) supercluster. We determined the high-density cores of the CB and the richest galaxy clusters in them, and studied their dynamical sta…
Orientation of cosmic web filaments with respect to the underlying velocity field
E. Tempel, N. I. Libeskind, Y. Hoffman +2
The large-scale structure of the Universe is characterised by a web-like structure made of voids, sheets, filaments, and knots. The structure of this so-called cosmic web is dictat…
Multimodality in galaxy clusters from SDSS DR8: substructure and velocity distribution
M. Einasto, J. Vennik, P. Nurmi +8
We search for the presence of substructure, a non-Gaussian, asymmetrical velocity distribution of galaxies, and large peculiar velocities of the main galaxies in galaxy clusters wi…
Groups and clusters of galaxies in the SDSS DR8. Value-added catalogues
E. Tempel, E. Tago, L. J. Liivamägi
Aims. We intend to compile a new galaxy group and cluster sample of the latest available SDSS data, adding several parameter for the purpose of studying the supercluster network, g…
SDSS DR7 superclusters. Morphology
M. Einasto, L. J. Liivamagi, E. Tago +5
We study the morphology of a set of superclusters drawn from the SDSS DR7. We calculate the luminosity density field to determine superclusters from a flux- limited sample of galax…
SDSS DR7 superclusters. The catalogues
L. J. Liivamägi, E. Tempel, E. Saar
We have constructed a set of supercluster catalogues for the galaxies from the SDSS survey main and luminous red galaxy (LRG) flux-limited samples. To delineate superclusters, we c…
Galaxy morphology, luminosity and, environment in the SDSS DR7
E. Tempel, E. Saar, L. J. Liivamägi +4
We study the influence of the environment on the evolution of galaxies by investigating the luminosity function (LF) of galaxies of different morphological types and colours at dif…
Estimation of time delays from unresolved photometry
A. Hirv, T. Eenmäe, T. Liimets +2
Longtime monitoring of gravitational lens systems is often done using telescopes and recording equipment with modest resolution. Still, it would be interesting to get as much infor…
