  • Bar rejuvenation in S0 galaxies? 
    Barway, Sudhanshu; Saha, Kanak (Oxford University Press on behalf of the Royal Astronomical Society, 2020-07)
    Based on the colour measurements from a multiband, multicomponent 2D decompositions of S0 and spiral galaxies using SDSS images, we found that bars are bluer in S0 galaxies compared to the spiral galaxies. Most of the S0s ...
  • The central region of the enigmatic Malin 1 
    Saha, Kanak; Dhiwar, Suraj; Barway, Sudhanshu; Narayan, Chaitra; Tandon, Shyam (Indian Academy of Sciences, 2021-10)
    Malin 1, being a class of giant low surface galaxies, continues to surprise us even today. The HST/F814W observation has shown that the central region of Malin 1 is more like a normal SB0/a galaxy, while the rest of the ...
  • Unveiling an Old Disk around a Massive Young Leaking Blueberry in SDSS-IV MaNGA 
    Paswan, Abhishek; Saha, Kanak; Borgohain, Anshuman; Leitherer, Claus; Dhiwar, Suraj (American Astronomical Society, 2022-04-10)
    Extreme emission-line galaxies, such as blue compact dwarfs (BCDs), Green Peas (GPs), and blueberries in the local universe are potential candidates for understanding the nature of galaxies that reionized the early universe. ...
  • Witnessing the star formation quenching in L* ellipticals 
    Dhiwar, Suraj; Saha, Kanak; Dekel, Avishai; Paswan, Abhishek; Pandey, Divya; Cortesi, Arianna; Pandge, Mahadev (Oxford University Press on behalf of Royal Astronomical Society, 2023-02)
    We study the evolution of L∗ elliptical galaxies in the colour–magnitude diagram in terms of their star formation history and environment, in an attempt to learn about their quenching process. We have visually extracted ...
