Fundamental physics with ESPRESSO: Constraints on Bekenstein and dark energy models from astrophysical and local probes
C. J. A. P. Martins, S. Cristiani, G. Cupani +21
Dynamical scalar fields in an effective four-dimensional field theory are naturally expected to couple to the rest of the theory's degrees of freedom, unless some new symmetry is p…
Fundamental Physics with ESPRESSO, Constraining a simple parametrisation for varying
Vitor da Fonseca, Tiago Barreiro, Nelson J. Nunes +24
The spectrograph ESPRESSO recently obtained a limit on the variation of the fine-structure constant, , through measurements along the line of sight of a bright quasar with a pre…
Fundamental physics with ESPRESSO: Precise limit on variations in the fine-structure constant towards the bright quasar HE 05154414
Michael T. Murphy, Paolo Molaro, Ana C. O. Leite +40
The strong intervening absorption system at redshift 1.15 towards the very bright quasar HE 05154414 is the most studied absorber for measuring possible cosmological variations…
Supernovae in paired host galaxies
T. A. Nazaryan, A. R. Petrosian, A. A. Hakobyan +5
We investigate the influence of close neighbor galaxies on the properties of supernovae (SNe) and their host galaxies using 56 SNe located in pairs of galaxies with different level…

Paired galaxies with different activity levels and their supernovae
T. A. Nazaryan, A. R. Petrosian, A. A. Hakobyan +5
We investigate the influence of close neighbor galaxies on the properties of supernovae (SNe) and their host galaxies using 56 SNe located in pairs of galaxies with different level…
On the Nature of Unconfirmed Supernovae
L. S. Aramyan, A. R. Petrosian, A. A. Hakobyan +5
We study the nature of 39 unconfirmed supernovae (SNe) from the sky area covered by the Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8), using available photometric and imagin…
Supernovae and their host galaxies. I. The SDSS DR8 database and statistics
A. A. Hakobyan, V. Zh. Adibekyan, L. S. Aramyan +5
(Abridged) In this first paper of a series, we report the creation of large and well-defined database that combines extensive new measurements and a literature search of 3876 super…
The Second Byurakan Survey Galaxies. I. The Optical Database
M. Gyulzadyan, B. Mclean, V. Zh. Adibekyan +4
A database for the entire catalog of the Second Byurakan Survey (SBS) galaxies is presented. It contains new measurements of their optical parameters and additional information tak…
A catalog of Kazarian galaxies
M. A. Kazarian, V. Zh. Adibekyan, B. McLean +2
The entire Kazarian galaxies (KG) catalog is presented which combines extensive new measurements of their optical parameters with a literature and database search. The measurements…
The spectral investigation of seven HII regions in Kazarian galaxies
V. Zh. Adibekyan
According to SDSS DR5 spectra the spectrophotometric investigations of seven HII regions of six Kazarian galaxies are conducted. The abundances of heavy elements and helium and als…
