Improved analytical modeling of the non-linear power spectrum in modified gravity cosmologies
Suhani Gupta, Wojciech A. Hellwing, Maciej Bilicki
Reliable analytical modeling of the non-linear power spectrum (PS) of matter perturbations is among the chief pre-requisites for cosmological analyses from the largest sky surveys.…
Bending the web: exploring the impact of modified gravity on the density field and halo properties within the cosmic web
Suhani Gupta, Simon Pfeifer, Punyakoti Ganeshaiah Veena +1
This work investigates the impact of different Modified Gravity (MG) models on the large-scale structures (LSS) properties in relation to the cosmic web (CW), using N-body simulati…
Universality of the halo mass function in modified gravity cosmologies
Suhani Gupta, Wojciech A. Hellwing, Maciej Bilicki +1
We study the halo mass function (HMF) in modified gravity (MG) models using a set of large -body simulations -- the ELEPHANT suite. We consider two popular beyond-general relati…
Probing gravity with redshift-space distortions: effects of tracer bias and sample selection
Jorge Enrique GarcÃa-Farieta, Wojciech A. Hellwing, Suhani Gupta +1
We investigate clustering properties of dark matter halos and galaxies to search for optimal statistics and scales where possible departures from general relativity (GR) could be f…
Dynamics of pairwise motions in the fully non-linear regime in LCDM and Modified Gravity cosmologies
Mariana Jaber, Wojciech A. Hellwing, Jorge E. GarcÃa-Farieta +2
In contrast to our understanding of density field tracers, the modelling of direct statistics pertaining to the cosmic velocity field remains open to significant opportunities for…
Personalized Artificial General Intelligence (AGI) via Neuroscience-Inspired Continuous Learning Systems
Rajeev Gupta, Suhani Gupta, Ronak Parikh +3
Artificial Intelligence has made remarkable advancements in recent years, primarily driven by increasingly large deep learning models. However, achieving true Artificial General In…
