Separating halo and disk stars in galaxies with Fuzzy Set Theory
Amit Mondal, Biswajit Pandey
Disk and halo stars are generally classified using several conventional methods, such as the Toomre diagram, sharp cuts in metallicity ([Fe/H]), vertical distance (…
From metallicity distributions to mutual information: A new perspective on stellar halo assembly
Amit Mondal, Biswajit Pandey
The metallicity structure of stellar halos encodes the fossil record of galaxy assembly, tracing the chemical evolution and dynamical imprint of past mergers. Using five Milky Way-…
Probing cosmic isotropy with Gamma-ray bursts: A dipole and quadrupole analysis of BATSE and Fermi GBM data
Debosi Mondal, Biswajit Pandey, Amit Mondal
The cosmological principle, asserting large-scale homogeneity and isotropy, underpins the standard model of cosmology. Testing its validity using independent astronomical probes re…
Tracing correlations between galaxy properties across the Cosmic Web: An IllustrisTNG-based study
Anindita Nandi, Biswajit Pandey, Prakash Sarkar
We explore the impact of cosmic web environments on galaxy properties such as colour, stellar mass, star formation rate, and stellar metallicity, using a stellar mass-matc…
Revealing a transitional epoch of large-scale cosmic anisotropy in the quasar distribution
Amit Mondal, Biswajit Pandey, Krishna Ghosh
The Cosmological Principle posits that the Universe is isotropic on the largest scales. While widely supported, this foundational assumption remains testable. We analyse the angula…
Galaxy quenching across the Cosmic Web: disentangling mass and environment with SDSS DR18
Anindita Nandi, Biswajit Pandey
We investigate the influence of large-scale cosmic web environments on galaxy quenching using a volume-limited, stellar mass-matched galaxy sample from SDSS DR18. Galaxies are clas…
Triggering and quenching in the shadow of AGN: How does AGN proximity affect star formation in the EAGLE simulation?
Apashanka Das, Biswajit Pandey
Active galactic nuclei (AGN) inject vast amounts of energy into their surroundings and are widely recognised as key drivers of galaxy evolution through feedback processes. Although…
Spatial and velocity anisotropies of stellar halos across cosmic web environments: Insights from IllustrisTNG simulation
Amit Mondal, Biswajit Pandey, Anindita Nandi
The role of large-scale environment in shaping the structural and kinematic properties of stellar halos remains an open question. We investigate whether the cosmic web environments…
The long road to the Green Valley: Tracing the evolution of the Green Valley galaxies in the EAGLE simulation
Apashanka Das, Biswajit Pandey
We study the evolution of the progenitors of the present-day Green Valley (GV) galaxies across redshift using data from the EAGLE simulations. We identify the present-day…
