Dynamical analysis of the dark matter and central black hole mass in the dwarf spheroidal Leo I
Maria Jose Bustamante-Rosell, Eva Noyola, Karl Gebhardt +4
We measure the central kinematics for the dwarf spheroidal galaxy Leo I using integrated-light measurements and previously published data. We find a steady rise in the velocity dis…
The MAVERIC Survey: Still No Evidence for Accreting Intermediate-mass Black Holes in Globular Clusters
Evangelia Tremou, Jay Strader, Laura Chomiuk +8
We present the results of an ultra-deep, comprehensive radio continuum survey for the accretion signatures of intermediate-mass black holes in globular clusters. The sample, imaged…
Deep radio imaging of 47 Tuc identifies the peculiar X-ray source X9 as a new black hole candidate
J. C. A. Miller-Jones, J. Strader, C. O. Heinke +8
We report the detection of steady radio emission from the known X-ray source X9 in the globular cluster 47 Tuc. With a double-peaked C IV emission line in its ultraviolet spectrum…
A re-evaluation of the central velocity-dispersion profile in NGC 6388
Nora Lützgendorf, Karl Gebhardt, Holger Baumgardt +4
Recently, two independent groups found very different results when measuring the central velocity dispersion of the galactic globular cluster NGC 6388 with different methods. While…
Intermediate-mass black holes in globular clusters: observations and simulations
Nora Lützgendorf, Markus Kissler-Patig, Karl Gebhardt +9
The study of intermediate-mass black holes (IMBHs) is a young and promising field of research. Formed by runaway collisions of massive stars in young and dense stellar clusters, in…
Central rotations of Milky Way Globular Clusters
Maximilian H. Fabricius, Eva Noyola, Surangkhana Rukdee +6
Most Milky Way globular clusters (GCs) exhibit measurable flattening, even if on a very low level. Both cluster rotation and tidal fields are thought to cause this flattening. Neve…
