  • Chemical enrichment of stars due to accretion from the ISM during the Galaxy's assembly 
    Shen, Sijing; Kulkarni, Girish; Madau, Piero; Mayer, Lucio (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Using the Eris zoom-in cosmological simulation of assembly of a Milky Way analogue, we study the chemical enrichment of stars due to accretion of metal-enriched gas from the interstellar medium (ISM) during the Galaxy's ...
  • The Complementary Roles of Feedback and Mergers in Building the Gaseous Halo and the X-Ray Corona of Milky-Way-sized Galaxies 
    Sokołowska, A.; Babul, A.; Mayer, L.; Shen, Sijing; Madau, Piero (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We use high-resolution cosmological hydrodynamical simulations of Milky-Way-sized galaxies with varying supernova feedback strengths and merger histories to investigate the formation of their gaseous halos and especially ...
  • The baryon cycle of Seven Dwarfs with superbubble feedback 
    Mina, Mattia; Shen, Sijing; Keller, Benjamin Walter; Mayer, Lucio; Madau, Piero; Wadsley, James (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    We present results from a high-resolution, cosmological, ΛCDM simulation of a group of field dwarf galaxies with the “superbubble” model for clustered SN feedback, accounting for thermal conduction and cold gas evaporation. ...
  • The Dawn of Disk Formation in a Milky Way-sized Galaxy Halo: Thin Stellar Disks at z > 4 
    Tamfal, Tomas; Mayer, Lucio; Quinn, Thomas R.; Babul, Arif; Madau, Piero; Capelo, Pedro R.; Shen, Sijing; Staub, Marius (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    We present results from GigaEris, a cosmological, N-body hydrodynamical "zoom-in" simulation of the formation of a Milky Way-sized galaxy halo with unprecedented resolution, encompassing of order a billion particles within ...
  • The origin of cold gas in the circumgalactic medium 
    Decataldo, Davide; Shen, Sijing; Mayer, Lucio; Baumschlager, Bernhard; Madau, Piero (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)
    Context. The presence of cold gas (T ≲ 104 K) in the circumgalactic medium (CGM) of galaxies has been confirmed in observations and in high-resolution simulations, but its origin is still a puzzle. Possible mechanisms are ...
