The Astrophysical Journal, 2023 We present kinematics of six local extremely metal-poor galaxies (EMPGs) with low metallicities (0.016–0.098 Z _⊙ ) and low stellar masses (10 ^4.7 –10 ^7.6 M _⊙ ).

MUFASA: Galaxy Formation Simulations With Meshless Hydrodynamics [PDF]
, 2016 We present the mufasa suite of cosmological hydrodynamic simulations, which employs the gizmo meshless finite mass (MFM) code including H_2-based star formation, nine-element chemical evolution, two-phase kinetic outflows following scalings from the ...

The Astrophysical Journal, 2023 We study the spatially resolved stellar populations of 444 galaxies at 0.3 < z < 6.0 in two clusters (WHL 0137–08 and MACS 0647+70) and a blank field, combining imaging data from the Hubble Space Telescope and JWST to perform spatially resolved spectral ...

Deep Learning for Galaxy Mergers in the Galaxy Main Sequence [PDF]
, 2019 Starburst galaxies are often found to be the result of galaxy mergers. As a result, galaxy mergers are often believed to lie above the galaxy main sequence: the tight correlation between stellar mass and star formation rate.

The Formation of Galaxies [PDF]
Symposium - International Astronomical Union, 1983 The presently fashionable ideas for galaxy formation are reviewed briefly, and it is concluded that the standard isothermal heirarchy fits the available data best. A simple infall picture is presented which explains many of the observed properties of disk galaxies.

The dark nemesis of galaxy formation : why hot haloes trigger black hole growth and bring star formation to an end [PDF]
, 2016 Galaxies fall into two clearly distinct types: `blue-sequence' galaxies that are rapidly forming young stars, and `red-sequence' galaxies in which star formation has almost completely ceased.

Gas-Rich Companions of Isolated Galaxies [PDF]
, 1999 We have used the VLA to search for gaseous remnants of the galaxy formation process around six extremely isolated galaxies. We found two distinct HI clouds around each of two galaxies in our sample (UGC 9762 & UGC 11124).

Breaking the hierarchy of galaxy formation [PDF]
, 2005 Recent observations of the distant Universe suggest that much of the stellar mass of bright galaxies was already in place at z > 1. This presents a challenge for models of galaxy formation because massive halos are assembled late in the hierarchical ...

Properties of Galaxy Groups in the SDSS: II.- AGN Feedback and Star Formation Truncation [PDF]
, 2006 Successfully reproducing the galaxy luminosity function and the bimodality in the galaxy distribution requires a mechanism that can truncate star formation in massive haloes.
