Simulation of the loss-cone instability in spherical systems. II. Dominating Keplerian potential
E. V. Polyachenko, P. Berczik, A. Just +1
A new so-called `gravitational loss-cone instability' in stellar systems has recently been investigated theoretically in the framework of linear perturbation theory and proved to b…
Simulation of the loss-cone instability in spherical systems. I. Dominating harmonic potential
E. V. Polyachenko, P. Berczik, A. Just +1
A new so-called `gravitational loss-cone instability' in stellar systems has recently been investigated theoretically in the framework of linear perturbation theory and proved to b…
Properties of galaxies with an offset between the position angles of the major kinematic and photometric axes
L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko +4
We derive the photometric, kinematic, and abundance characteristics of 18 star-forming MaNGA galaxies with fairly regular velocity fields and surface brightness distributions and w…
Globular Cluster Systems and X-Ray Atmospheres in Galaxies
Gretchen L. H. Harris, Iurii V. Babyk, William E. Harris +1
We compare the empirical relationships between the mass of a galaxy's globular system M_GCS, the gas mass in the hot X-ray atmosphere M_X within a fiducial radius of 5 r_e, the tot…
'Scraggy' dark halos around bulge-less spiral galaxies
I. D. Karachentsev, V. E. Karachentseva
We use a sample of 220 face-on bulge-less galaxies situated in the low density environment to estimate their total mass via orbital motions of supposed rare satellites. Our inspect…
The star cluster survivability after gas expulsion is independent of the impact of the Galactic tidal field
B. Shukirgaliyev, G. Parmentier, P. Berczik +1
We study the impact of the tidal field on the survivability of star clusters following instantaneous gas expulsion. Our model clusters are formed with a centrally-peaked star-forma…
