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…
MARTINI: Mock Array Radio Telescope Interferometry of the Neutral ISM
Kyle A. Oman
MARTINI is a modular Python package that takes smoothed-particle hydrodynamics (SPH) simulations of galaxies as input and creates synthetic spatially- and/or spectrally-resolved ob…
An overlooked source of uncertainty in the mass of the Milky Way
Kyle A. Oman, Alexander H. Riley
In the conventional approach to decomposing a rotation curve into a set of contributions from mass model components, the measurements of the rotation curve at different radii are t…
Hydrodynamical simulations of merging galaxy clusters: giant dark matter particle colliders, powered by gravity
Ellen L. Sirks, David Harvey, Richard Massey +7
Terrestrial particle accelerators collide charged particles, then watch the trajectory of outgoing debris - but they cannot manipulate dark matter. Fortunately, dark matter is the…
The onset of bar formation in a massive galaxy at
Aristeidis Amvrosiadis, Samuel Lange, James Nightingale +13
We examine the morphological and kinematical properties of SPT-2147, a strongly lensed, massive, dusty, star-forming galaxy at . Combining data from JWST, HST, and ALMA,…
ARTEMIS emulator: exploring the effect of cosmology and galaxy formation physics on Milky Way-mass haloes and their satellites
Shaun T. Brown, Azadeh Fattahi, Ian G. McCarthy +3
We present the new ARTEMIS Emulator suite of high resolution (baryon mass of M) zoom-in simulations of Milky Way mass systems. Here, three ha…
