Globular cluster formation in the context of galaxy formation and evolution [PDF]
, 2014 The formation of globular clusters (GCs) remains one of the main unsolved problems in star and galaxy formation. The past decades have seen important progress in constraining the physics of GC formation from a variety of directions.

Analysis of the Functions of Cosmology Dust in Galaxy Formation
Theoretical and Natural Science, 2023 The physical laws related to star formation in galaxies are the key to understanding the formation and evolution of galaxies. The dust in the interstellar medium has a significant effect on both the star formation and the observational properties of the ...

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 ...

Formation and Evolution of Disk Galaxies [PDF]
Proceedings of the International Astronomical Union, 2003 AbstractGlobal 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. Primary observational constraints on disk galaxy formation and evolution include the Schmidt-Kennicutt law, 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 ...

Scaling Properties of Galaxy Groups
Universe, 2021 Galaxy groups and poor clusters are more common than rich clusters, and host the largest fraction of matter content in the Universe. Hence, their studies are key to understand the gravitational and thermal evolution of the bulk of the cosmic matter ...

Chemie Ingenieur Technik, EarlyView., 2023 Let us consider an alternative perspective on climate change: The sum of solar radiation and heat generated by human activity result in a net energy input of 1.96 times that of the Sun on the Earth's surface. The expanding global population is expected to exacerbate this issue. Potential solutions are proposed, including replacement and heat recycling.

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.

Astraeus I: the interplay between galaxy formation and reionization [PDF]
, 2020 We introduce a new self-consistent model of galaxy evolution and reionization, ASTRAEUS (semi-numerical rAdiative tranSfer coupling of galaxy formaTion and Reionization in N-body dArk mattEr simUlationS), which couples a state-of-the-art N-body ...

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.
