Stellar Halo Memory: A New Observable for Galactic Archaeology
Biswajit Pandey, Amit Mondal
The Galactic stellar halo preserves a fossil record of the Milky Way's assembly history, yet there is currently no unified framework for quantifying how much of this information su…
Entropic backreaction from cosmic structure formation: a thermodynamic approach to the late-time cosmological tensions
Biswajit Pandey
High-precision cosmological observations have revealed persistent tensions within the standard CDM paradigm, most notably the discrepancy in the Hubble constant and the lower th…
A Multi-parameter Fuzzy Set Framework for Classifying Red, Blue, and Green Valley Galaxies
Amit Mondal, Biswajit Pandey
We present a data-driven fuzzy set framework for classifying galaxies into the red sequence, blue cloud, and green-valley populations using multiple observables from the Sloan Digi…
An information-theoretic bound on cosmic coherence in finite-volume simulations
Biswajit Pandey, Anindita Nandi
We quantify the physical memory of the cosmic density field using mutual information between -body snapshots at different redshifts, removing a random baseline to isolate gravit…
