Early Evolution of Disk Galaxies: Formation of Bulges in Clumpy Young Galactic Disks [PDF]
, 1999 A new idea is proposed for the origin of bulges in spiral galaxies. Numerical simulations of protogalactic collapse suggest strongly that galactic bulges have been assembled from massive clumps formed in galactic disks in their early evolutionary phase ...

A Comprehensive Study of Galaxies at z ∼ 9–16 Found in the Early JWST Data: Ultraviolet Luminosity Functions and Cosmic Star Formation History at the Pre-reionization Epoch [PDF]
Astrophysical Journal Supplement Series, 2022 We conduct a comprehensive study on dropout galaxy candidates at z ∼ 9–16 using the first 90 arcmin2 James Webb Space Telescope (JWST) Near Infrared Camera images taken by the early release observations (ERO) and early release science programs.

STAR FORMATION IN GALAXIES ALONG THE HUBBLE SEQUENCE [PDF]
, 1998 Observations of star formation rates (SFRs) in galaxies provide vital clues to the physical nature of the Hubble sequence and are key probes of the evolutionary histories of galaxies.

Starburst99: Synthesis Models for Galaxies with Active Star Formation [PDF]
, 1999 Starburst99 is a comprehensive set of model predictions for spectrophotometric and related properties of galaxies with active star formation. The models are an improved and extended version of the data set previously published by Leitherer & Heckman.

Inferring the star formation histories of massive quiescent galaxies with bagpipes: evidence for multiple quenching mechanisms [PDF]
Monthly notices of the Royal Astronomical Society, 2017 We present Bayesian Analysis of Galaxies for Physical Inference and Parameter EStimation, or BAGPIPES, a new Python tool which can be used to rapidly generate complex model galaxy spectra and to fit these to arbitrary combinations of spectroscopic and ...

EVOLUTION OF THE STARS AND GAS IN GALAXIES. [PDF]
, 2022 Essentially everything of astronomical interest is either part of a galaxy, or from a galaxy, or otherwise relevant to the origin or evolution of galaxies. Diverse examples are that the isotropic composition of meteorites provides clues to the history of

A parsec-resolution simulation of the Antennae galaxies: formation of star clusters during the merger [PDF]
, 2014 We present a hydrodynamical simulation of an Antennae-like galaxy merger at parsec resolution, including a multi-component model for stellar feedback and reaching numerical convergence in the global star formation rate for the first time.

Spectroscopic confirmation of four metal-poor galaxies at z = 10.3–13.2 [PDF]
Nature Astronomy, 2022 As part of the JWST Advanced Deep Extragalactic Survey (JADES), NIRSpec has spectroscopically confirmed four young and metal-poor galaxies at redshift 10.3–13.2, from an early epoch of galaxy formation.

THE AVERAGE STAR FORMATION HISTORIES OF GALAXIES IN DARK MATTER HALOS FROM z = 0–8 [PDF]
, 2012 We present a robust method to constrain average galaxy star formation rates (SFRs), star formation histories (SFHs), and the intracluster light (ICL) as a function of halo mass.
