Star Cluster Formation in Cosmological Simulations. II. Effects of Star Formation Efficiency and Stellar Feedback
Hui Li, Oleg Y. Gnedin, Nickolay Y. Gnedin
The implementation of star formation and stellar feedback in cosmological simulations plays a critical role in shaping galaxy properties. In the first paper of the series, we prese…
Disrupted Globular Clusters and the Gamma-Ray Excess in the Galactic Centre
Giacomo Fragione, Fabio Antonini, Oleg Y. Gnedin
The Fermi Large Area Telescope has provided the most detailed view toward the Galactic Centre (GC) in high-energy gamma rays. Besides the interstellar emission and point-source con…
Theia: Faint objects in motion or the new astrometry frontier
The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
AGN Activity in Nucleated Galaxies as Measured by Chandra
Adi Foord, Elena Gallo, Edmund Hodges-Kluck +4
Motivated by theoretical expectations that Nuclear Star Clusters (NSCs) in galactic centers may provide a favorable environment for super-massive black holes to form and/or efficie…
