A universal model for the accretion rates and formation times of dark matter halos
Ankita Bera, Benedikt Diemer
The formation histories of halos set the baseline rate at which galaxies accrete gas over cosmic time. While a number of models describe these histories and their derivative, the m…

Towards Reconciling Reionization with JWST: The Role of Bright Galaxies and Strong Feedback
Ankita Bera, Sultan Hassan, Robert Feldmann +2
The elevated UV luminosity functions (UVLF) from recent James Webb Space Telescope (JWST) have challenged the viability of existing theoretical models. To address this, we use a se…
