An optical/NIR survey of globular clusters in early-type galaxies II. Ages of GC systems and the relation to galaxy morphology
globular clusters early-type galaxies II
2011/1/10
Context: Some photometric studies of extragalactic globular cluster (GC) systems using the optical and near-infrared colour combination have suggested the presence of a large fraction of intermediate-...
The Mass-Radius(-Rotation?) Relation for Low-Mass Stars
Mass-Radius Relation Low-Mass Stars
2010/11/15
The fundamental properties of low-mass stars are not as well understood as those of their more
massive counterparts. The best method for constraining these properties, especially masses and radii,is ...
Consistency relation for the Lorentz invariant single-field inflation
shape bispectrum Lorentz invariant single-field inflation
2010/3/19
In this paper we compute the sizes of equilateral and orthogonal shape bispectrum for the general Lorentz invariant single-field inflation. The stability of field theory implies a non-negative square ...
On the final definition of the causal boundary and its relation with the conformal boundary
causal structure Kronheimer and Penrose construction chronological sets and completions causal boundary conformal boundary globally hyperbolic spacetimes naked singularities Penrose-Carter diagrams
2010/3/19
The notion of causal boundary $\partial M$ for a strongly causal spacetime $M$ has been a controversial topic along last decades: on one hand, some attempted definitions were not fully consistent, on ...
A MODIFIED THEORETICAL Sigma-D RELATION FOR SUPERNOVA REMNANTS：I. THE CASE OF CONSTANT TEMPERATURE WITHIN THE SUPERNOVA REMNANT
ISM supernova remnants-radiation mechanisms thermal-radio continuum ISM
2009/3/13
We present a modification of the theoretical Σ − D relation for
supernova remnants (SNRs) in the adiabatic expansion phase. This modification
is based on the convolution of the relation first ...
