Hidden Disruption in Milky Way-like Satellite Galaxy Populations
Gray Thoron, Nora Shipp, Alexander H. Riley +9
Determining whether a satellite galaxy is tidally disrupting from photometric observations alone remains a fundamental challenge in near-field cosmology. Cosmological simulations o…
No Stream Left Unscathed: The imprint of a host galaxy
Arpit Arora, Peter S. Ferguson, Jacob Nibauer +11
Stellar streams from disrupted globular clusters are excellent probes of dark matter (DM) subhalos. Observed Milky Way streams display a remarkable diversity of features: spurs, ga…
The DECam MAGIC Survey: Investigating the Jet Stellar Stream with Photometric Metallicities
H. Q. Do, A. Chiti, P. S. Ferguson +27
Stellar streams are dynamically fragile structures formed by the tidal disruption of dwarf galaxies and stellar clusters. These objects are valuable tracers of the gravitational po…
Probing Atomic Dark Matter with Stellar Streams in Milky Way-Mass Galaxies
Lucas S. Mandacarú Guerra, Stephanie O'Neil, Mariangela Lisanti +7
We present the first detailed analysis of the effects of dissipative dark matter on stellar streams. As a concrete example, we generate a cosmological hydrodynamic zoom-in simulati…
Auriga Streams III: the mass-metallicity relation does not rule out tidal mass loss in Local Group satellites
Alexander H. Riley, Rebekka Bieri, Alis J. Deason +6
The mass-metallicity relation is a fundamental galaxy scaling law that has been extended to the faintest systems in the Local Group. We show that the small scatter in this relation…
Crowded Field Photometry with Rubin: Exploring 47 Tucanae with Data Preview 1
Tobin M. Wainer, James R. A. Davenport, Eric C. Bellm +15
We analyze imaging from Data Preview 1 of the Vera C. Rubin Observatory to explore the performance of early LSST pipelines in the 47 Tucanae field. The coadd-\texttt{object} catalo…
Shaping the Milky Way: The interplay of mergers and cosmic filaments
Arpit Arora, Nicolás Garavito-Camargo, Robyn E. Sanderson +12
The large-scale morphology of Milky Way (MW)-mass dark matter (DM) halos is shaped by two key processes: filamentary accretion from the cosmic web and interactions with massive sat…
Auriga Streams II: orbital properties of tidally disrupting satellites of Milky Way-mass galaxies
Nora Shipp, Alexander H. Riley, Christine M. Simpson +7
Galaxies like the Milky Way are surrounded by complex populations of satellites at all stages of tidal disruption. In this paper, we present a dynamical study of the disrupting sat…
Auriga Streams I: disrupting satellites surrounding Milky Way-mass haloes at multiple resolutions
Alexander H. Riley, Nora Shipp, Christine M. Simpson +8
In a hierarchically formed Universe, galaxies accrete smaller systems that tidally disrupt as they evolve in the host's potential. We present a complete catalogue of disrupting gal…
StreamGen: Connecting Populations of Streams and Shells to Their Host Galaxies
Adriana Dropulic, Nora Shipp, Stacy Kim +3
In this work, we study how the abundance and dynamics of populations of disrupting satellite galaxies change systematically as a function of host galaxy properties. We apply a theo…
Efficient and accurate force replay in cosmological-baryonic simulations
Arpit Arora, Robyn Sanderson, Christopher Regan +8
We construct time-evolving gravitational potential models for a Milky Way-mass galaxy from the FIRE-2 suite of cosmological-baryonic simulations using basis function expansions. Th…
