Globular Cluster Formation from Colliding Substructure
Piero Madau, Alessandro Lupi, Juerg Diemand +2
We investigate a scenario where the formation of Globular Clusters (GCs) is triggered by high-speed collisions between infalling atomic-cooling subhalos during the assembly of the…
Quantifying tidal stream disruption in a simulated Milky Way
Emily Sandford, Andreas H. W. Kuepper, Kathryn V. Johnston +1
Simulations of tidal streams show that close encounters with dark matter subhalos induce density gaps and distortions in on-sky path along the streams. Accordingly, observing disru…
Milky Way Mass and Potential Recovery Using Tidal Streams in a Realistic Halo
Ana Bonaca, Marla Geha, Andreas H. W. Kuepper +3
We present a new method for determining the Galactic gravitational potential based on forward modeling of tidal stellar streams. We use this method to test the performance of smoot…
Warm dark matter does not do better than cold dark matter in solving small-scale inconsistencies
Aurel Schneider, Donnino Anderhalden, Andrea Maccio +1
Over the last decade, warm dark matter (WDM) has been repeatedly proposed as an alternative scenario to the standard cold dark matter (CDM) one, potentially resolving several disag…
Density Profiles of CDM Microhalos and their Implications for Annihilation Boost Factors
Donnino Anderhalden, Juerg Diemand
In a standard cold dark matter (CDM) cosmology, microhalos at the CDM cutoff scale are the first and smallest objects expected to form in the universe. Here we present results of h…
Structure Finding in Cosmological Simulations: The State of Affairs
Alexander Knebe, Frazer R. Pearce, Hanni Lux +32
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade…
