The Distribution of Supernovae Relative to Spiral Arms of Host Disc Galaxies
L. S. Aramyan, A. A. Hakobyan, A. R. Petrosian +7
Using a sample of 215 supernovae (SNe), we analyse their positions relative to the spiral arms of their host galaxies, distinguishing grand-design (GD) spirals from non-GD (NGD) ga…
Supernovae and their host galaxies - IV. The distribution of supernovae relative to spiral arms
L. S. Aramyan, A. A. Hakobyan, A. R. Petrosian +7
Using a sample of 215 supernovae (SNe), we analyze their positions relative to the spiral arms of their host galaxies, distinguishing grand-design (GD) spirals from non-GD (NGD) ga…
On the Interaction in a Quartet of Galaxies
A. A. Yeghiazaryan, A. A. Hakobyan, T. A. Nazaryan
We performed the Fabry-Perot scanning interferometry of the quartet of galaxies NGC 7769, 7770, 7771 and 7771A in Ha line and studied their velocity fields. We found that the rotat…
Ha Velocity Fields and Galaxy Interaction in the Quartet of Galaxies NGC 7769, 7770, 7771 and 7771A
A. A. Yeghiazaryan, T. A. Nazaryan, A. A. Hakobyan
The quartet of galaxies NGC 7769, 7770, 7771 and 7771A is a system of interacting galaxies. Close interaction between galaxies caused characteristic morphological features: tidal a…
Supernovae and their host galaxies - II. The relative frequencies of supernovae types in spirals
A. A. Hakobyan, T. A. Nazaryan, V. Zh. Adibekyan +8
We present an analysis of the relative frequencies of different supernova (SN) types in spirals with various morphologies and in barred or unbarred galaxies. We use a well-defined…
Relative frequencies of supernovae versus properties of spiral hosts
A. A. Hakobyan, T. A. Nazaryan, V. Zh. Adibekyan +8
In this work, we present an analysis of SNe number ratios in spiral galaxies with different morphological subtypes, luminosities, sSFR, and metallicities, to provide important info…
Close pairs of galaxies with different activity levels
T. A. Nazaryan, A. R. Petrosian, A. A. Hakobyan +2
We selected and studied 180 pairs with dV < 800 km/s and Dp < 60 kpc containing Markarian (MRK) galaxies to investigate the dependence of galaxies' integral parameters, star-format…
