Formation and evolution of disk galaxies [PDF]
Proceedings of the International Astronomical Union, 2008 Global star formation is the key to understanding galaxy disk formation. This in turn depends on gravitational instability of disks and continuing gas accretion as well as minor merging. A key component is feedback from supernovae.

Merger Induced Globular Cluster Formation and Galaxy Evolution [PDF]
The Astrophysical Journal, 2008 Based on the earlier work of Gunn and McCrea we model the formation of globular clusters in merging galaxies. Neutral hydrogen observations of dwarf irregular galaxies as well as more luminous systems are used to provide the key parameters of the model ...

What Regulates Galaxy Evolution? Open Questions in Our Understanding of Galaxy Formation and Evolution [PDF]
New Astronomy Reviews, 2014 In April 2013, a workshop entitled "What Regulates Galaxy Evolution" was held at the Lorentz Center. The aim of the workshop was to bring together the observational and theoretical community working on galaxy evolution, and to discuss in depth of the ...

Cosmological evolution and hierarchical galaxy formation [PDF]
Monthly Notices of the Royal Astronomical Society, 1999 We provide a new multi-waveband compilation of the data describing the cosmological evolution of quasars, and discuss a model that attributes the evolution to variation in the rate of merging between dark halos in a hierarchical universe. We present a new Press-Schechter calculation of the expected merger rate and show that this can reproduce the ...

Galaxy formation and evolution: low-surface-brightness galaxies [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We investigate in detail the hypothesis that low surface brightness galaxies (LSB) differ from ordinary galaxies simply because they form in halos with large spin parameters. We compute star formation rates using the Schmidt law, assuming the same gas infall dependence on surface density as used in models of the Milky Way.

The Astrophysical Journal, 2023 We present the first result in exploring the gaseous halo and galaxy correlation using the Dark Energy Spectroscopic Instrument survey validation data in the Cosmic Evolution Survey (COSMOS) and Hyper Suprime-Cam field.

Chemodynamical Modelling of Galaxy Formation and Evolution [PDF]
Astrophysics and Space Science, 2002 We present our recently developed 3-dimensional chemodynamical code for galaxy evolution. This code follows the evolution of different galactic components like stars, dark matter and different components of the interstellar medium (ISM), i.e. a diffuse gaseous phase and the molecular clouds.

Targeted decrease of portal hepatic pressure gradient improves ascites control after TIPS
Hepatology, EarlyView., 2022 The river diagram demonstrates that after transjugular intrahepatic portosystemic shunt insertion (TIPS) the majority of patients without ascites and 50% of the patients with ascites detectable at ultrasound, show the best response in the long term follow‐up.
