The mass accretion history of dark matter haloes down to Earth mass (2023)
Journal Article
Liu, Y., Gao, L., Bose, S., Frenk, C. S., Jenkins, A., Springel, V., Wang, J., White, S. D. M., & Zheng, H. (2023). The mass accretion history of dark matter haloes down to Earth mass. Monthly Notices of the Royal Astronomical Society, 527(4), 11740-11750. https://doi.org/10.1093/mnras/stae003

We take advantage of the unprecedented dynamical range provided by the ‘Cosmic-Zoom’ project to study the mass accretion history (MAH) of present-day dark matter haloes o v er the entire mass range present in the Lambda cold dark matter paradigm when...

Ghostly Galaxies: Accretion-dominated Stellar Systems in Low-mass Dark Matter Halos (2023)
Journal Article
Wang, C.-W., Cooper, A. P., Bose, S., Frenk, C. S., & Hellwing, W. A. (2023). Ghostly Galaxies: Accretion-dominated Stellar Systems in Low-mass Dark Matter Halos. Astrophysical Journal, 958(2), Article 166. https://doi.org/10.3847/1538-4357/ad011d

Wide-area deep imaging surveys have discovered large numbers of extremely low surface brightness (LSB) dwarf galaxies, which challenge galaxy formation theory and, potentially, offer new constraints on the nature of dark matter. Here we discuss one a... Read More about Ghostly Galaxies: Accretion-dominated Stellar Systems in Low-mass Dark Matter Halos.

Gravitational-wave event rates as a new probe for dark matter microphysics (2023)
Journal Article
Mosbech, M. R., Jenkins, A. C., Bose, S., Boehm, C., Sakellariadou, M., & Wong, Y. Y. (2023). Gravitational-wave event rates as a new probe for dark matter microphysics. Physical Review D, 108(4), Article 043512. https://doi.org/10.1103/physrevd.108.043512

We show that gravitational waves have the potential to unravel the microphysical properties of dark matter due to the dependence of the binary black hole merger rate on cosmic structure formation, which is itself highly dependent on the dark matter s...

The MillenniumTNG Project: the impact of baryons and massive neutrinos on high-resolution weak gravitational lensing convergence maps (2023)
Journal Article
Ferlito, F., Springel, V., Davies, C. T., Hernández-Aguayo, C., Pakmor, R., Barrera, M., White, S. D. M., Delgado, A. M., Hadzhiyska, B., Hernquist, L., Kannan, R., Bose, S., & Frenk, C. (2023). The MillenniumTNG Project: the impact of baryons and massive neutrinos on high-resolution weak gravitational lensing convergence maps. Monthly Notices of the Royal Astronomical Society, 524(4), 5591-5606. https://doi.org/10.1093/mnras/stad2205

We study weak gravitational lensing convergence maps produced from the MILLENNIUM TNG simulations by direct projection of the mass distribution on the past backwards lightcone of a fiducial observer. We explore the lensing maps over a large dynamic r...

The MillenniumTNG Project: refining the one-halo model of red and blue galaxies at different redshifts (2023)
Journal Article
Hadzhiyska, B., Hernquist, L., Eisenstein, D., Delgado, A. M., Bose, S., Kannan, R., …Frenk, C. (2023). The MillenniumTNG Project: refining the one-halo model of red and blue galaxies at different redshifts. Monthly Notices of the Royal Astronomical Society, 524(2), 2524–2538. https://doi.org/10.1093/mnras/stad279

Luminous red galaxies (LRGs) and blue star-forming emission-line galaxies (ELGs) are key tracers of large-scale structure used by cosmological surveys. Theoretical predictions for such data are often done via simplistic models for the galaxy–halo con...

The early release science results from JWST have yielded an unexpected abundance of high-redshift luminous galaxies that seems to be in tension with current theories of galaxy formation. However, it is currently difficult to draw definitive conclusio... Read More about The MillenniumTNG project: the galaxy population at z ≥ 8.
