How Many Worlds Could There Be? David Lewis and Advanced Modalizing

Analytic Philosophy, EarlyView.
ABSTRACT Advanced modalizing, namely, possibilities and necessities concerning modal space itself, is problematic for a Lewis‐style analysis of modality. A popular solution, proposed by Divers, postulates explicit semantic clauses for a collapse of advanced modalizing, to the conclusion that all such matters are, if true in the first place, both ...

Bar Formation during a Gaia-Sausage-Enceladus-like Merger Event

The Astrophysical Journal
Bars are among the most prominent galactic structures, yet their formation mechanisms remain incompletely understood. They can form either internally, via dynamical instabilities, or externally, triggered by interactions with other galaxies.

Are Prices Really Affected by Mergers? [PDF]

During the 80s, several empirical studies have shown a positive correlation between concentration, prices and profits. It is well known that these estimates all suffer from simultaneity bias: market structure and prices are affected by common factors ...

The star formation history of early-type galaxies in the fornax cluster [PDF]

, 1998
We have measured central line strengths and line-strength gradients for a complete sample of early-type galaxies in the Fornax cluster, comprising 11 elliptical and 11 lenticular galaxies, more luminous than M(_B) = -17.

The Problem of Psychonomic Harmony

Philosophy and Phenomenological Research, EarlyView.
ABSTRACT The problem of nomological harmony is the problem of explaining why the laws of nature match or apply to the states of the universe in a way that results in temporal evolution. The problem of psychophysical harmony is the problem of explaining why phenomenal states are paired with physical states and other phenomenal states in surprisingly ...

Galaxy Mergers from the Largest to the Smallest Scales: Introduction and Overview [PDF]

, 2012
Galaxy mergers encompass a wide range of astrophysical phenomena, including cosmological considerations, gas and stellar dynamics, AGN evolution, and mergers of the central SMBHs.

Galaxy interactions I. Major and minor mergers

, 2011
Aims. We study galaxy pair samples selected from the Sloan Digital Sky Survey (SDSS-DR7) and we perform an analysis of minor and major mergers with the aim of investigating the dependence of galaxy properties on interactions. Methods.

On Our Cosmic (In)significance

Ratio, EarlyView.
ABSTRACT This article discusses three interpretations of cosmic significance, all of which reveal something important about the notion of significance. Along the way, it proposes a unified view of significance by combining elements of each of the views.

Evolution of Nuclear Star Cluster in Dwarf Galaxy through Mergers and In Situ Star Formation

The Astrophysical Journal
Nuclear star clusters (NSCs) are dense stellar systems located at the centers of galaxies. Employing Enzo- Abyss , which integrates hydrodynamics with a direct N -body solver, we introduce a simulation capable of resolving the evolution of NSCs within a ...
