The radial distribution of core-collapse supernovae in spiral host galaxies
A. A. Hakobyan, G. A. Mamon, A. R. Petrosian +2
With the goal of providing constraints on the nature of the progenitors of core-collapse supernovae, we compare their radial distribution within their spiral host galaxies with the…
The nature of compact groups of galaxies from cosmological simulations
G. A. Mamon, E. Diaz-Gimenez
The nature of compact groups (CGs) of galaxies, apparently so dense that the galaxies often overlap, is still a subject of debate: Are CGs roughly as dense in 3D as they appear in…
The mass and anisotropy profiles of galaxy clusters from the projected phase space density: testing the method on simulated data
Radoslaw Wojtak, Ewa L. Lokas, Gary A. Mamon +1
We present a new method of constraining the mass and velocity anisotropy profiles of galaxy clusters from kinematic data. The method is based on a model of the phase space density…
Kinematic deprojection and mass inversion of spherical systems of known velocity anisotropy
Gary A. Mamon, Gwenael Boué
Traditionally, the mass / velocity anisotropy degeneracy (MAD) inherent in the spherical, stationary, non-streaming Jeans equation has been handled by assuming a mass profile and f…
Five supernova survey galaxies in the southern hemisphere. I. Optical and near-infrared database
A. A. Hakobyan, A. R. Petrosian, G. A. Mamon +8
The determination of the supernova (SN) rate is based not only on the number of detected events, but also on the properties of the parent galaxy population. This is the first paper…
