Galaxy evolution in the cosmic web: the relative impact of nodes and filaments in the EAGLE simulation
Suman Sarkar, Biswajit Pandey, Apashanka Das
Galaxies evolve within the intricate geometry of the cosmic web, yet the distinct roles of its primary components - nodes and filaments remain incompletely understood. Using the EA…
Negentropy as Diagnostic of Cosmic Density Fields and Dynamical Dark Energy Models
Suman Sarkar
We employ negentropy (), defined as the difference between the information content of a non-Gaussian probability distribution and a Gaussian with identical variance, as an infor…
Identifying lopsidedness in spiral galaxies using a Deep Convolutional Neural Network
Biju Saha, Suman Sarkar, Arunima Banerjee
About 30\% of disk galaxies show lopsidedness in their stellar disk. Although such a large-scale asymmetry in the disk can be primarily looked upon as a long-lived mode (), th…
Unveiling galaxy pair alignment in cosmic filaments: A 3D exploration using EAGLE simulation
Suman Sarkar, Biswajit Pandey
We investigate how galaxy pairs are oriented in three dimensions within cosmic filaments using data from the EAGLE simulation. We identify filament spines using DisPerSE and isolat…
