Low [O/Fe] Ratio in a Luminous Galaxy at the Early Cosmic Epoch (z > 10): Signature of Short Delay Time or Bright Hypernovae/Pair-instability Supernovae?

open access: yesThe Astrophysical Journal
We present an [O/Fe] ratio of a luminous galaxy GN-z11 at z = 10.60 derived with the deep public JWST/NIRSpec data. We fit the medium-resolution grating (G140M, G235M, and G395M) data with the model spectra consisting of BPASS-stellar and Cloudy -nebular

The Tully-Fisher Zero Point Problem

open access: yes, 2008
A long standing problem for hierarchical disk galaxy formation models has been the simultaneous matching of the zero point of the Tully-Fisher relation and the galaxy luminosity function (LF).

The evolving disk galaxy population

open access: yes, 2008
In this contribution, I present a simplified overview of the evolution of the disk galaxy population since z=1, and a brief discussion of a few open questions.

CEERS: Increasing Scatter along the Star-forming Main Sequence Indicates Early Galaxies Form in Bursts

open access: yesThe Astrophysical Journal
We present the star formation rate–stellar mass (SFR– M _* ) relation for galaxies in the Cosmic Evolution Early Release Science survey at 4.5 ≤ z ≤ 12.
