MaNGA galaxies with off-centered spots of enhanced gas velocity dispersion
L. S. Pilyugin, B. Cedres, I. A. Zinchenko +8
Off-centered spots of the enhanced gas velocity dispersion, s, are revealed in some galaxies from the MaNGA survey. Aiming to clarify the origin of the spots of enhanced s, we exam…
Two types of distribution of the gas velocity dispersion of MaNGA galaxies
L. S. Pilyugin, I. A. Zinchenko, M. A. Lara-Lopez +2
The distribution of the gas velocity dispersion sigma across the images of 1146 MaNGA galaxies is analyzed. We find that there are two types of distribution of the gas velocity dis…
Circumnuclear regions of different BPT types in star-forming MaNGA galaxies: AGN detectability
L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko +3
We consider the circumnuclear regions of MaNGA galaxies. The spectra are classified as AGN-like, HII-region-like (or SF-like), and intermediate (INT) spectra according to their pos…
Peculiar motions of the gas at the centre of the barred galaxy UGC 4056
I. A. Zinchenko, L. S. Pilyugin, F. Sakhibov +6
We derive the circular velocity curves of the gaseous and stellar discs of UGC 4056, a giant barred galaxy with an active galactic nucleus (AGN). We analyse UGC 4056 using the 2D s…
Breaks in surface brightness profiles and radial abundance gradients in the discs of spiral galaxies
L. S. Pilyugin, E. K Grebel, I. A. Zinchenko +2
We examine the relation between breaks in the surface brightness profiles and radial abundance gradients within the optical radius in the discs of 134 spiral galaxies from the CALI…
