Radial stability of a family of anisotropic Hernquist models with and without a supermassive black hole
P. Buyle, E. Van Hese, S. De Rijcke +1
We present a method to investigate the radial stability of a spherical anisotropic system that hosts a central supermassive black hole (SBH). Such systems have never been tested be…
Completely analytical families of anisotropic gamma-models
Pieter Buyle, Chris Hunter, Herwig Dejonghe
We present new analytical distribution functions for anisotropic spherical galaxies. They have the density profiles of the gamma-models, which allow a wide range of central density…
The CO content of the Local Group dwarf irregular galaxies IC5152, UGCA438, and the Phoenix dwarf
Pieter Buyle, Dolf Michielsen, Sven De Rijcke +2
We present a search for CO(1->0) emission in three Local Group dwarf irregular galaxies: IC5152, the Phoenix dwarf, and UGCA438, using the ATNF Mopra radio telescope. Our scans lar…
The v_c-sigma_c relation in low mass and low surface brightness galaxies
Pieter Buyle, Laura Ferrarese, Gianfranco Gentile +3
We present an updated investigation of the relation between large scale disk circular velocity, v_c, and bulge velocity dispersion, sigma_c. New bulge velocity dispersions are meas…
The HI content of E+A galaxies
P. Buyle, D. Michielsen, S. De Rijcke +3
We present deep single-dish HI observations of a sample of six nearby E+A galaxies (0.05<z<0.1). A non-negligible fraction of a local sample of E+As are detected in HI. In four gal…
Upper limits on the central black hole masses of 47Tuc and NGC6397
S. De Rijcke, P. Buyle, H. Dejonghe
We present upper-limits on the masses of the putative central intermediate-mass black holes in two nearby Galactic globular clusters: 47Tuc (NGC104), the second brightest Galactic…
