Disk Galaxy Models Driven by Stochastic Self-Propagating Star Formation

Open Astronomy, 2010
We present a model of chemical and spectrophotometric evolution of disk galaxies based on a stochastic self-propagating star formation scenario. The model incorporates galaxy formation through the process of accretion, chemical and photometric evolution ...

Galaxy Evolution with Manifold Learning [PDF]

Entropy
Matter in the early Universe was nearly uniform, and galaxies emerged through the gravitational growth of small primordial density fluctuations. Astrophysics has been trying to unveil the complex physical phenomena that have caused the formation and ...

Galaxy formation theory [PDF]

Physics Reports, 2010
We review the current theory of how galaxies form within the cosmological framework provided by the cold dark matter paradigm for structure formation. Beginning with the pre-galactic evolution of baryonic material we describe the analytical and numerical

Models of Late-type Disk Galaxies: 1-D Versus 2-D

Open Astronomy, 2014
We investigate the effects of stochasticity on the observed galaxy parameters by comparing our stochastic star formation two-dimensional (2-D) galaxy evolution models with the commonly used one-dimensional (1-D) models with smooth star formation. The 2-D

Morphologies of Galaxies at z ≳ 9 Uncovered by JWST/NIRCam Imaging: Cosmic Size Evolution and an Identification of an Extremely Compact Bright Galaxy at z ∼ 12

The Astrophysical Journal, 2023
We present morphologies of galaxies at z ≳ 9 resolved by JWST/NIRCam 2–5 μ m imaging. Our sample consists of 22 galaxy candidates identified by stringent dropout and photo- z criteria in GLASS, CEERS, SMACS J0723, and Stephan’s Quintet flanking fields ...

LIMFAST. I. A Seminumerical Tool for Line Intensity Mapping

The Astrophysical Journal, 2023
We present LIMFAST, a seminumerical code for simulating high-redshift galaxy formation and cosmic reionization as revealed by multitracer line intensity mapping (LIM) signals.

LIMFAST. II. Line Intensity Mapping as a Probe of High-redshift Galaxy Formation

The Astrophysical Journal, 2023
The epoch of reionization (EoR) offers a unique window into the dawn of galaxy formation, through which high-redshift galaxies can be studied by observations of both themselves and their impact on the intergalactic medium.

Chemical Evolution of Galaxies [PDF]

, 2000
Chemical evolution of galaxies brings together ideas on stellar evolution and nucleosynthesis with theories of galaxy formation, star formation and galaxy evolution, with all their associated uncertainties.

Monolithic View of Galaxy Formation and Evolution

Galaxies, 2014
We review and critically discuss the current understanding of galaxy formation and evolution limited to Early Type Galaxies (ETGs) as inferred from the observational data and briefly contrast the hierarchical and quasi-monolithic paradigms of formation ...

Parallelization, Special Hardware and Post-Newtonian Dynamics in Direct N - Body Simulations [PDF]

, 2008
The formation and evolution of supermassive black hole (SMBH) binaries during and after galaxy mergers is an important ingredient for our understanding of galaxy formation and evolution in a cosmological context, e.g.
