The Milky Way stellar halo is twisted and doubly broken: insights from DESI DR2 Milky Way Survey observation
Songting Li, Wenting Wang, Sergey E. Koposov +45
Using K giants from the second data release (DR2) of the Dark Energy Spectroscopic Instrument (DESI) Milky Way (MW) Survey, we measure the shape, orientation, radial profile, and d…
Modelling the evolution and influence of dust in cosmological simulations that include the cold phase of the interstellar medium
James W. Trayford, Joop Schaye, Camila Correa +7
While marginal in mass terms, dust grains play an outsized role in both the physics and observation of the interstellar medium (ISM). However, explicit modelling of this ISM consti…
Luminosity and stellar mass functions of faint photometric satellites around spectroscopic central galaxies from DESI Year-1 Bright Galaxy Survey
Wenting Wang, Xiaohu Yang, Yipeng Jing +47
We measure the luminosity functions (LFs) and stellar mass functions (SMFs) of photometric satellite galaxies around spectroscopically identified isolated central galaxies (ICGs).…
The unabridged satellite luminosity function of Milky Way-like galaxies in CDM: the contribution of "orphan" satellites
Isabel Santos-Santos, Carlos Frenk, Julio Navarro +2
We study the abundance, radial distribution, and orbits of luminous satellites in simulations of MW-mass dark halos in the LCDM cosmology. We follow the evolution of a halo from th…
AuriDESI: Mock Catalogues for the DESI Milky Way Survey
Namitha Kizhuprakkat, Andrew P. Cooper, Alexander H. Riley +31
The Dark Energy Spectroscopic Instrument Milky Way Survey (DESI MWS) will explore the assembly history of the Milky Way by characterising remnants of ancient dwarf galaxy accretion…
Unraveling the Complexity of Dwarf Galaxy Dynamics: A study of Binary Orbital Motions
Wenting Wang, Ling Zhu, Yipeng Jing +8
We investigate the impact of binary orbital motions on the dynamical modeling of dwarf galaxies with intrinsic line-of-sight velocity dispersions () of 1 to 9 km/s. Using…
The MillenniumTNG Project: Inferring cosmology from galaxy clustering with accelerated N-body scaling and subhalo abundance matching
Sergio Contreras, Raul E. Angulo, Volker Springel +11
We introduce a novel technique for constraining cosmological parameters and galaxy assembly bias using non-linear redshift-space clustering of galaxies. We scale cosmological N-bod…
The MillenniumTNG Project: The galaxy population at
Rahul Kannan, Volker Springel, Lars Hernquist +11
The early release science results from have yielded an unexpected abundance of high-redshift luminous galaxies that seems to be in tension with current theories of…
Galactic satellite systems in CDM, WDM and SIDM
Victor J. Forouhar Moreno, Alejandro Benitez-Llambay, Shaun Cole +1
We investigate the population of bright satellites () of haloes of mass comparable to that of the Milky Way in cosmological simulations in whi…
On the Edge: the relation between stellar and dark matter haloes of Milky Way-mass galaxies
Anna Genina, Alis Deason, Carlos Frenk
We investigate the build-up of the accreted stellar and dark matter haloes of Milky Way-like galaxies in APOSTLE suite of cosmological hydrodynamics simulations. We show that the s…
Is the core-cusp problem a matter of perspective: Jeans Anisotropic Modeling against numerical simulations
Wenting Wang, Ling Zhu, Zhaozhou Li +14
Mock member stars for 28 dwarf galaxies are constructed from the cosmological Auriga simulation, which reflect the dynamical status of realistic stellar tracers. The axis-symmetric…
Baryon-driven decontraction in Milky Way mass haloes
Victor J. Forouhar Moreno, Alejandro Benítez-Llambay, Shaun Cole +1
We select a sample of Milky Way (MW) mass haloes from a high-resolution version of the EAGLE simulation to study their inner dark matter (DM) content and how baryons alter it. As i…
Observing the stellar halo of Andromeda in cosmological simulations: the Auriga2PAndAS pipeline
Guillaume F. Thomas, Nicolas F. Martin, Azadeh Fattahi +10
We present a direct comparison of the Pan-Andromeda Archaeological Survey (PAndAS) observations of the stellar halo of M31 with the stellar halos of 6 galaxies from the Auriga simu…
The Milky Way system in LCDM cosmological simulations
Qi Guo, Andrew Cooper, Carlos Frenk +2
We apply a semi-analytic galaxy formation model to two high resolution cosmological N-body simulations to investigate analogues of the Milky Way system. We select these according t…
Creating mock catalogues of stellar haloes from cosmological simulations
Ben Lowing, Wenting Wang, Andrew Cooper +4
We present a new technique for creating mock catalogues of the individual stars that make up the accreted component of stellar haloes in cosmological simulations and show how the c…
The formation of shell galaxies similar to NGC 7600 in the cold dark matter cosmogony
Andrew P. Cooper, David Martinez-Delgado, John Helly +6
We present new deep observations of 'shell' structures in the halo of the nearby elliptical galaxy NGC 7600, alongside a movie of galaxy formation in a cold dark matter universe (a…
