The Impact of Bulges on the Radial Distribution of Supernovae in Disc Galaxies
A. A. Hakobyan, A. G. Karapetyan, L. V. Barkhudaryan +6
We present the results of the analysis of the impact of bulges on the radial distributions of the different types of supernovae (SNe) in the stellar discs of host galaxies with var…
Faint Dwarf Galaxies in Hickson Compact Group 90
Yasna Ordenes-Briceño, Matthew A. Taylor, Thomas H. Puzia +11
We report the discovery of a very diverse set of five low-surface brightness (LSB) dwarf galaxy candidates in Hickson Compact Group 90 (HCG 90) detected in deep U- and I-band image…
The impact of bars on the radial distribution of supernovae in disc galaxies
A. A. Hakobyan, A. G. Karapetyan, L. V. Barkhudaryan +6
We present an analysis of the impact of bars on the radial distributions of the different types of supernovae (SNe) in the stellar discs of host galaxies with various morphologies.…
Outflows Driven by Quasars in High-Redshift Galaxies with Radiation Hydrodynamics
Rebekka Bieri, Yohan Dubois, Joakim Rosdahl +3
The quasar mode of Active Galactic Nuclei (AGN) in the high-redshift Universe is routinely observed in gas-rich galaxies together with large-scale AGN-driven winds. It is crucial t…
Prospects for annihilating Dark Matter towards Milky Way's dwarf galaxies by the Cherenkov Telescope Array
Valentin Lefranc, Paolo Panci, Gary A. Mamon
We derive the Cherenkov Telescope Array (CTA) sensitivity to dark matter (DM) annihilation in several primary channels, over a broad range of DM masses. These sensitivities are est…
Do the stellar populations of the brightest two group galaxies depend on the magnitude gap?
M. Trevisan, G. A. Mamon, H. G. Khosroshahi
We investigate how the stellar populations of the inner regions of the first and the second brightest group galaxies (respectively BGGs and SBGGs) vary as a function of magnitude g…
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…
