Ruffled Feathers: Merger-driven galaxy size growth and structural transformation in EAGLE
Kai Wang, Carlton Baugh, Sownak Bose +9
Galaxy mergers drive both the size growth and the transformation from discs to spheroids, yet the prescriptions used to model these processes in semi-analytic frameworks have not b…
Inflow-driven galaxy evolution - I. Revealing the physics of the fundamental metallicity relation
Kai Wang, Carlton Baugh, N. F. Boardman +11
We present a unified physical framework for the fundamental metallicity relation (FMR), based on the mass-continuity equations. The FMR is not merely the anti-correlation between s…
EFT-Ramses: a code to simulate the effective field theory of dark energy
Nathaniel Ota Woodcock, Sownak Bose, Yunhao Gao +1
While the standard CDM paradigm is in excellent agreement with most current cosmological observations, theoretical challenges surrounding the cosmological constant () have st…
The VST ATLAS Survey IV: Galaxy, LRG and QSO bias and HODs via ACT CMB Lensing
Harshnoor Kaur, T. Shanks, S. Bose +1
The paper measures the clustering bias and halo occupation of VST ATLAS galaxies, luminous red galaxies, and quasars by cross‑correlating their distributions with the high‑resoluti…
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…
JWST spectroscopy of galaxies at : Damped Ly absorbers reveal efficient star formation and hidden redshift biases
Kasper E. Heintz, Clara L. Pollock, Joris Witstok +23
Recent observations with JWST have revealed a remarkable population of surprisingly luminous galaxies at redshifts . Their abundance exceed predictions from simulations and e…
