Limitations to the "basic'' HOD model and beyond
Boryana Hadzhiyska, Sownak Bose, Daniel Eisenstein +2
We make use of the IllustrisTNG cosmological, hydrodynamical simulations to test fundamental assumptions of the mass-based Halo Occupation Distribution (HOD) approach to modelling…
Improving Small-Scale CMB Lensing Reconstruction
Boryana Hadzhiyska, Blake D. Sherwin, Mathew Madhavacheril +1
Over the past decade, the gravitational lensing of the Cosmic Microwave Background (CMB) has become a powerful tool for probing the matter distribution in the Universe. The standar…
CDM or self-interacting neutrinos? - how CMB data can tell the two models apart
Minsu Park, Christina D. Kreisch, Jo Dunkley +2
Of the many proposed extensions to the CDM paradigm, a model in which neutrinos self-interact until close to the epoch of matter-radiation equality has been shown to provide a g…
