The dark matter halo mass function in the cosmology at all times and over all scales -- from planetary to galaxy cluster masses
Haonan Zheng, Sownak Bose, Carlos S. Frenk +7
The dark matter halo mass function is one of the most fundamental predictions of structure formation theory and cosmological simulations. We present the full halo mass function in…
Illuminating the Physics of Cosmic Origin and Evolution: A UK Space Frontiers 2035 White Paper
Florian Beutler, Eva-Maria Mueller, Seshadri Nadathur +61
Understanding the Universe's origins and evolution remains one of the most fundamental challenges in modern cosmology. This white paper explores three key science priorities in thi…
Buried but not destroyed: the evolution from prompt cusps to NFW haloes
Yuchan Wang, Sownak Bose, Carlos Frenk +1
The internal structure of dark matter haloes encodes their assembly history and offers critical insight into the nature of dark matter and structure formation. Analytical studies a…
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…
The MillenniumTNG Project: Impact of massive neutrinos on the cosmic large-scale structure and the distribution of galaxies
César Hernández-Aguayo, Volker Springel, Sownak Bose +10
We discuss the cold dark matter plus massive neutrinos simulations of the MillenniumTNG (MTNG) project, which aim to improve understanding of how well ongoing and future large-scal…
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…
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…
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 impact and response of minihalos and the inter-halo medium on cosmic reionization
Tsang Keung Chan, Alejandro Benitez-Llambay, Tom Theuns +2
An ionization front (I-front) that propagates through an inhomogeneous medium is slowed down by self-shielding and recombinations. We perform cosmological radiation hydrodynamics s…
The MillenniumTNG Project: Intrinsic alignments of galaxies and halos
Ana Maria Delgado, Boryana Hadzhiyska, Sownak Bose +9
The intrinsic alignment (IA) of observed galaxy shapes with the underlying cosmic web is a source of contamination in weak lensing surveys. Sensitive methods to identify the IA sig…
