Orbital dynamics and histories of satellite galaxies around Milky Way-mass galaxies in the FIRE simulations
Isaiah B. Santistevan, Andrew Wetzel, Erik Tollerud +2
The orbits of satellite galaxies encode rich information about their histories. We investigate the orbital dynamics and histories of satellite galaxies around Milky Way (MW)-mass h…
On the stability of tidal streams in action space
Arpit Arora, Robyn E. Sanderson, Nondh Panithanpaisal +3
In the Gaia era it is increasingly apparent that traditional static, parameterized models are insufficient to describe the mass distribution of our complex, dynamically evolving Mi…
Modeling the gravitational potential of a cosmological dark matter halo with stellar streams
Robyn E. Sanderson, Johanna Hartke, Amina Helmi
Stellar streams result from the tidal disruption of satellites and star clusters as they orbit a host galaxy, and can be very sensitive probes of the gravitational potential of the…
Stream-subhalo interactions in the Aquarius simulations
Robyn E. Sanderson, Carlos Vera-Ciro, Amina Helmi +1
We perform the first self-consistent measurement of the rate of interactions between stellar tidal streams created by disrupting satellites and dark subhalos in a cosmological simu…
Action-space clustering of tidal streams to infer the Galactic potential
Robyn E. Sanderson, Amina Helmi, David W. Hogg
We present a new method for constraining the Milky Way halo gravitational potential by simultaneously fitting multiple tidal streams. This method requires full three-dimensional po…
