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…
Five Supernova Survey Galaxies in the Southern Hemisphere: Supernova Ia Rates
A. A. Hakobyan, A. R. Petrosian, G. A. Mamon +9
Based on the database of 56 supernovae (SNe) events discovered in 3838 galaxies of the southern hemisphere, we compute the rate of SNe of different types along the Hubble sequence…
