Mock halo catalogs: assigning unresolved halo properties using correlations with local halo environment
Sujatha Ramakrishnan, Aseem Paranjape, Ravi K. Sheth
Large-scale sky surveys require companion large volume simulated mock catalogs. To ensure precision cosmology studies are unbiased, the correlations in these mocks between galaxy p…
A sea of tides: star formation and the central-satellite dichotomy in a continuum of tidal environments
Jolanta Zjupa, Aseem Paranjape, Oliver Hahn +1
The environment-dependent bimodality of the distribution of stellar mass () and specific star formation rate (sSFR) of galaxies, and its explanation in terms of the central…
Separate Universe calibration of the dependence of halo bias on cosmic web anisotropy
Sujatha Ramakrishnan, Aseem Paranjape
We use the Separate Universe technique to calibrate the dependence of linear and quadratic halo bias and on the local cosmic web environment of dark matter haloes. We d…
Analytical halo models of cosmic tidal fields
Aseem Paranjape
The non-linear cosmic web environment of dark matter haloes plays a major role in shaping their growth and evolution, and potentially also affects the galaxies that reside in them.…
Three- and two-point spatial correlations of IGM at : Cloud based analysis using simulations
Soumak Maitra, Raghunathan Srianand, Prakash Gaikwad +3
Ly forest absorption spectra decomposed into multiple Voigt profile components (clouds) allow us to study clustering of intergalactic medium (IGM) as a function of HI column den…
Studying the Lyman- optical depth fluctuations at using fast semi-numerical methods
T. Roy Choudhury, Aseem Paranjape, Sarah E. I. Bosman
We present a computationally efficient and fast semi-numerical technique for simulating the Lyman- (Ly) absorption optical depth in presence of neutral hydrogen "islands" lef…
