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…
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…
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…
The roles of environment and interactions on the evolution of red and blue galaxies in the EAGLE simulation
Apashanka Das, Biswajit Pandey
We study the evolution of the red and blue galaxies from to using the EAGLE simulation. The galaxies in the blue cloud and the red sequence are separated at each redshi…
Galaxy interactions in filaments and sheets: insights from EAGLE simulations
Apashanka Das, Biswajit Pandey, Suman Sarkar
We study the colour and star formation rates of paired galaxies in filaments and sheets using the EAGLE simulations. We find that the major pairs with pair separation kpc are…
Galaxy interactions in filaments and sheets: effects of the large-scale structures versus the local density
Apashanka Das, Biswajit Pandey, Suman Sarkar
The major interactions are known to trigger star formation in galaxies and alter their colour. We study the major interactions in filaments and sheets using the SDSS data to unders…
Do minor interactions trigger star formation in galaxy pairs?
Apashanka Das, Biswajit Pandey, Suman Sarkar
We analyze the galaxy pairs in a set of volume limited samples from the SDSS to study the effects of minor interactions on the star formation rate (SFR) and colour of galaxies. We…
On the origin of red spirals: Does assembly bias play a role?
Suman Sarkar, Biswajit Pandey, Apashanka Das
The formation of the red spirals is a puzzling issue in the standard picture of galaxy formation and evolution. Most studies attribute the colour of the red spirals to different en…
Galaxy interactions in different environments: An analysis of galaxy pairs from the SDSS
Apashanka Das, Biswajit Pandey, Suman Sarkar +1
We analyze the galaxy pairs in a volume limited sample () from the SDSS to study the effects of galaxy interactions on the star formation rate and colour of galaxies…
Green valley galaxies in the cosmic web: internal versus environmental quenching
Apashanka Das, Biswajit Pandey, Suman Sarkar
We analyze the SDSS data to classify the galaxies based on their colour using a fuzzy set-theoretic method and quantify their environments using the local dimension. We find that t…
