Journal Article
Kurmus, A., Bose, S., Lovell, M., Cyr-Racine, F.-Y., Vogelsberger, M., Pfrommer, C., & Zavala, J. (2022). The feasibility of constraining DM interactions with high-redshift observations by JWST. Monthly Notices of the Royal Astronomical Society, 516(1), 1524-1538. https://doi.org/10.1093/mnras/stac2195

Observations of the high redshift universe provide a promising avenue for constraining the nature of the dark matter (DM). This will be even more true with the advent of the James Webb Space Telescope (JWST). We run cosmological simulations of galaxy...

Modelling the galaxy–halo connection with machine learning (2022)
Journal Article
Delgado, A. M., Wadekar, D., Hadzhiyska, B., Bose, S., Hernquist, L., & Ho, S. (2022). Modelling the galaxy–halo connection with machine learning. Monthly Notices of the Royal Astronomical Society, 515(2), 2733-2746. https://doi.org/10.1093/mnras/stac1951

To extract information from the clustering of galaxies on non-linear scales, we need to model the connection between galaxies and haloes accurately and in a flexible manner. Standard halo occupation distribution (HOD) models make the assumption that... Read More about Modelling the galaxy–halo connection with machine learning.

Illustrating galaxy–halo connection in the DESI era with illustrisTNG (2022)
Journal Article
Yuan, S., Hadzhiyska, B., Bose, S., & Eisenstein, D. J. (2022). Illustrating galaxy–halo connection in the DESI era with illustrisTNG. Monthly Notices of the Royal Astronomical Society, 512(4), 5793-5811. https://doi.org/10.1093/mnras/stac830

We employ the hydrodynamical simulation ILLUSTRISTNG to inform the galaxy–halo connection of the Luminous Red Galaxy (LRG) and Emission Line Galaxy (ELG) samples of the Dark Energy Spectroscopic Instrument (DESI) survey at redshift z ∼ 0.8. Specifica... Read More about Illustrating galaxy–halo connection in the DESI era with illustrisTNG.

Constructing high-fidelity halo merger trees in abacussummit (2022)
Journal Article
Bose, S., Eisenstein, D. J., Hadzhiyska, B., Garrison, L. H., & Yuan, S. (2022). Constructing high-fidelity halo merger trees in abacussummit. Monthly Notices of the Royal Astronomical Society, 512(1), 837-854. https://doi.org/10.1093/mnras/stac555

Tracking the formation and evolution of dark matter haloes is a critical aspect of any analysis of cosmological N-body simulations. In particular, the mass assembly of a halo and its progenitors, encapsulated in the form of its merger tree, serves as...

Dynamics of intermediate-mass black holes wandering in the milky way galaxy using the illustris TNG50 simulation (2022)
Journal Article
Weller, E. J., Pacucci, F., Hernquist, L., & Bose, S. (2022). Dynamics of intermediate-mass black holes wandering in the milky way galaxy using the illustris TNG50 simulation. Monthly Notices of the Royal Astronomical Society, 511(2), 2229-2238. https://doi.org/10.1093/mnras/stac179

The detection of Intermediate-Mass Black Holes (IMBHs) in dwarf galaxies is crucial to closing the gap in the wide mass distribution of black holes (⁠∼3M⊙ to ∼5×1010M⊙⁠). IMBHs originally located at the centre of dwarfs that later collide with the Mi...
