    • The BPT Diagram in Cosmological Galaxy Formation Simulations: Understanding the Physics Driving Offsets at High Redshift 

      Garg, Prerak; Narayanan, Desika; Byler, Nell; Sanders, Ryan L.; Shapley, Alice E.; Strom, Allison L.; Davé, Romeel; Hirschmann, Michaela; Lovell, Christopher C.; Otter, Justin; Popping, Gergö; Privon, George C. (2022-02-15)
      The Baldwin, Philips, & Terlevich diagram of [O iii]/Hβ versus [N ii]/Hα (hereafter N2-BPT) has long been used as a tool for classifying galaxies based on the dominant source of ionizing radiation. Recent observations have ...

    • Investigating the Dominant Environmental Quenching Process in UVCANDELS/COSMOS Groups 

      Kuschel, Maxwell; Scarlata, Claudia; Mehta, Vihang; Teplitz, Harry I.; Rafelski, Marc; Wang, Xin; Sunnquist, Ben; Prichard, Laura; Grogin, Norman; Koekemoer, Anton; Windhorst, Rogier; Rutkowski, Michael; Alavi, Anahita; Chartab, Nima; Conselice, Christopher J.; Dai, Y. Sophia; Gawiser, Eric; Giavalisco, Mauro; Haro, Pablo Arrabal; Hathi, Nimish; Jansen, Rolf A.; Ji, Zhiyuan; Lucas, Ray A.; Mantha, Kameswara; Mobasher, Bahram; O’Connell, Robert W.; Robertson, Brant; Sattari, Zahra; Yung, L. Y. Aaron; Davé, Romeel; DeMello, Duilia; Dickinson, Mark; Ferguson, Henry; Finkelstein, Steven L.; Hayes, Matt; Howell, Justin; Kaviraj, Sugata; Mackenty, John W.; Siana, Brian (2023-04-12)
      We explore how the fraction of quenched galaxies changes in groups of galaxies with respect to the distance to the center of the group, redshift, and stellar mass to determine the dominant process of environmental quenching ...

    • Reproducing sub-millimetre galaxy number counts with cosmological hydrodynamic simulations 

      Lovell, Christopher C.; Geach, James E.; Davé, Romeel; Narayanan, Desika; Li, Qi (2021-01-04)
      Matching the number counts of high-$z$ sub-millimetre-selected galaxies (SMGs) has been a long standing problem for galaxy formation models. In this paper, we use 3D dust radiative transfer to model the sub-mm emission ...

    • Simba-c : An updated chemical enrichment model for galactic chemical evolution in the SIMBA simulation 

      Hough, Renier T.; Rennehan, Douglas; Kobayashi, Chiaki; Loubser, S. Ilani; Davé, Romeel; Babul, Arif; Cui, Weiguang (2023-10-30)
      We introduce a new chemical enrichment and stellar feedback model into GIZMO, using the SIMBA sub-grid models as a base. Based on the state-of-the-art chemical evolution model of Kobayashi et al., SIMBA-C tracks 34 elements ...
