Cosmic Ray Driven Outflows from the Large Magellanic Cloud: Contributions to the LMC Filament
Chad Bustard, Ellen G. Zweibel, Elena D'Onghia +2
In this paper, we build from previous work (Bustard et al. 2018) and present simulations of recent (within the past Gyr), magnetized, cosmic ray driven outflows from the Large Mage…
Fossil group origins X. Velocity segregation in fossil systems
S. Zarattini, J. A. L. Aguerri, A. Biviano +3
We want to study how the velocity segregation and the radial profile of the velocity dispersion depend on the prominence of the brightest cluster galaxies (BCGs). We divide a sampl…
Trojans in the Solar Neighborhood
Elena D'Onghia, J. Alfonso L. Aguerri
About 20% of stars in the solar vicinity are in the Hercules stream, a bundle of stars that move together with a velocity distinct from the Sun. Its origin is still uncertain. Here…
Discovery of new stellar groups in the Orion complex
Boquan Chen, Elena D'Onghia, João Alves +1
We test the ability of two unsupervised machine learning algorithms, \textit{EnLink} and Shared Nearest Neighbour (SNN), to identify stellar groupings in the Orion star-forming com…
Satellites of Satellites: The Case for Carina and Fornax
Stephen A. Pardy, Elena D'Onghia, Julio Navarro +6
We use the Auriga cosmological simulations of Milky Way (MW)-mass galaxies and their surroundings to study the satellite populations of dwarf galaxies in CDM. As expected from p…
The Magellanic Stream as a Probe of Astrophysics
Andrew J. Fox, Kathleen A. Barger, Joss Bland-Hawthorn +9
Extending for over 200 degrees across the sky, the Magellanic Stream together with its Leading Arm is the most spectacular example of a gaseous stream in the local Universe. The St…
Implications of a time-varying Galactic potential for determinations of the dynamical surface density
Tim Haines, Elena D'Onghia, Benoit Famaey +2
Recent studies have shown that the passage of a massive satellite through the disk of a spiral galaxy can induce vertical wobbles in the disk and produce features such as in-plane…
