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…
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…
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…
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…
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 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…
