A sea of tides: star formation and the central-satellite dichotomy in a continuum of tidal environments
TL;DR: In this paper, the authors revisited this framework in the context of the most extreme local tidal anisotropy experienced by each galaxy over cosmic time, which is an excellent proxy for environmental influence and support an alternate viewpoint in which a galaxy can be identified by the value of $\alpha_{\rm peak}$; rather than being placed on the central-satellite dichotomy, a galaxy is better classified by its location in a continuum of tidal environments.

Modelling the 21-cm Signal from the Epoch of Reionization and Cosmic Dawn
T. Roy Choudhury,Kanan K. Datta,Suman Majumdar,Raghunath Ghara,Aseem Paranjape,Rajesh Mondal,Somnath Bharadwaj,Saumyadip Samui +7 more
TL;DR: In this article, the authors focus on the theoretical models of reionization that have been worked out by various groups working in India with the upcoming SKA in mind These models include purely analytical and semi-numerical calculations as well as fully numerical radiative transfer simulations The predictions of the 21-cm signal from these models would be useful in constraining the properties of the early galaxies using the SKA data
Journal ArticleDOI
Global analysis of luminosity- and colour-dependent galaxy clustering in the Sloan Digital Sky Survey
TL;DR: In this paper, the authors presented a Halo Occupation Distribution (HOD) analysis of the luminosity and colour-dependent galaxy clustering in the Sloan Digital Sky Survey (SDSS) using a combination of clustering measurements in luminosity bins to perform a global likelihood analysis.
Journal ArticleDOI
Halo abundances and counts-in-cells: The excursion set approach with correlated steps
TL;DR: In this paper, Peacock and Heavens presented a simple approximation for the first crossing distribution of a single barrier of constant height by walks with correlated steps, which can be thought of as a correction to the distribution associated with what are smooth completely correlated walks.
Journal ArticleDOI
Halo bias in the excursion set approach with correlated steps
Aseem Paranjape,Ravi K. Sheth +1 more
TL;DR: In this article, the authors show that although different k-modes in the initial Gaussian field are uncorrelated, this is not true in real space: the values of the density field at a given spatial position, when smoothed on different real-space scales, are correlated in a nontrivial way.
