    • The Imprint of Clump Formation at High Redshift. II. The Chemistry of the Bulge 

      Debattista, Victor P.; Liddicott, David J.; Gonzalez, Oscar A.; Beraldo e Silva, Leandro; Amarante, João A. S.; Lazar, Ilin; Zoccali, Manuela; Valenti, Elena; Fisher, Deanne B.; Khachaturyants, Tigran; Nidever, David L.; Quinn, Thomas R.; Du, Min; Kassin, Susan (2023-04-07)
      In Paper I, we showed that clumps in high-redshift galaxies, having a high star formation rate density (ΣSFR), produce disks with two tracks in the [Fe/H]–[α/Fe] chemical space, similar to that of the Milky Way’s (MW’s) ...

    • The morphological mix of dwarf galaxies in the nearby Universe 

      Lazar, Ilin; Kaviraj, Sugata; Watkins, Aaron E.; Martin, Garreth; Bichang'a, Brian; Jackson, Ryan A. (2024-03-01)
      We use a complete, unbiased sample of 257 dwarf (10 8 M < M < 10 9.5 M) galaxies at z < 0.08, in the COSMOS field, to study the morphological mix of the dwarf population in low-density environments. Visual inspection of ...

    • Relaxed blue ellipticals: accretion-driven stellar growth is a key evolutionary channel for low mass elliptical galaxies 

      Lazar, Ilin; Kaviraj, Sugata; Martin, Garreth; Laigle, Clotilde; Watkins, Aaron; Jackson, Ryan (2023-04-30)
      How elliptical galaxies form is a key question in observational cosmology. While the formation of massive ellipticals is strongly linked to mergers, the low mass (M⋆/M⊙ < 10^9.5 regime remains less well explored. In ...
