Signatures of black hole seeding in the local Universe: Predictions from the BRAHMA cosmological simulations
Aklant K Bhowmick, Laura Blecha, Paul Torrey +8
The first "seeds" of supermassive black holes (BHs) continue to be an outstanding puzzle, and it is currently unclear whether the imprints of early seed formation survive today. He…
The THESAN project: tracking the expansion and merger histories of ionized bubbles during the Epoch of Reionization
Nathan Jamieson, Aaron Smith, Meredith Neyer +7
The growth of ionized hydrogen bubbles in the intergalactic medium around early luminous objects is a fundamental process during the Epoch of Reionization (EoR). In this study, we…
A smooth filament origin for distant prolate galaxies seen by JWST and HST
Alvaro Pozo, Tom Broadhurst, Razieh Emami +7
The initial gravitational collapse of Dark Matter and gas forms a universal filamentary network where the first galaxies form, with shapes and sizes that depend on the choice of Da…
Large dark matter content and steep metallicity profile predicted for Ultra-Diffuse Galaxies formed in high-spin halos
José A. Benavides, Laura V. Sales, Mario. G. Abadi +3
We study the stellar properties of a sample of simulated ultra-diffuse galaxies (UDGs) with stellar mass , selected from the TNG50 simul…
Unravelling the role of merger histories in the population of In situ stars: linking IllustrisTNG cosmological simulation to H3 survey
Razieh Emami, Lars Hernquist, Randall Smith +16
We undertake a comprehensive investigation into the distribution of in~situ stars within Milky Way-like galaxies, leveraging TNG50 simulations and comparing their predictions with…
Growth of high redshift supermassive black holes from heavy seeds in the BRAHMA cosmological simulations: Implications of overmassive black holes
Aklant K Bhowmick, Laura Blecha, Paul Torrey +6
JWST has recently revealed a large population of accreting black holes (BHs) in the early Universe. Even after accounting for possible systematic biases, the high-z $M_*-M_{\rm \rm…
