Group Scaling Relations From a Cosmological Hydrodynamic Simulation: No Pre-heating Required?
pre-heating entropy fl oors
2014/12/26
We investigate the X-ray vs. optical scaling relations of poor groups
to small clusters ( 100−700 km/s) identified in a cosmological hydro-
dynamic simulation of a ΛCDM universe, with cooli...
X-ray scaling relations of galaxy groups in a hydrodynamic cosmological simulation
theory clusters
2014/12/26
We examine the scalings of X-ray luminosity, temperature, and dark matter or galaxy velocity dispersion for galaxy groups in a ΛCDM cosmological simulation, which incorporates gravity, gas dynamics, r...
Scaling Relations and Optimization of Excitonic Energy Transfer Rates between One-Dimensional Molecular Aggregates
Scaling Relations Optimization of Exciton Energy Transfer Rates One-Dimensional Molecular Aggregates
2013/12/19
We theoretically study the distance, chain length, and temperature dependence of the electronic couplings as well as the excitonic energy transfer rates between onedimensional (1D) chromophore aggrega...
The SAURON Project - XIX. Optical and near-infrared scaling relations of nearby elliptical, lenticular and Sa galaxies
galaxies: bulges – galaxies: elliptical and lenticular, cD – galaxies: photometry – galaxies: structure – galaxies: stellar content – galaxies: fundamental parameters
2011/7/4
[Abridged] We present ground-based MDM V-band and Spitzer/IRAC 3.6um-band photometric observations of the 72 representative galaxies of the SAURON Survey. In combination with the SAURON stellar veloci...
We study the morphology of watersheds in two and three dimensional systems subjected to different degrees of spatial correlations. The response of these objects to small, local perturbations is also i...
Disk Galaxy Scaling Relations in the SFI++: Intrinsic Scatter and Applications
galaxies spirals – galaxies fundamental parameters – galaxies
2010/11/15
We study the scaling relations between the luminosities, sizes, and rotation velocities of disk galaxies in the SFI++, with a focus on the size-luminosity (RL) and size-rotation velocity (RV ) relatio...
HIFLUGCS: Galaxy Cluster Scaling Relations between X-ray Luminosity, Gas Mass, Cluster Radius, and Velocity Dispersion
Cosmology observations — (Cosmology:) dark matter — Galaxies clusters: general — Methods
2010/11/1
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and between cluster radius and velocity dispersion (r500 − )...
Evidence of major dry mergers at M* > 2 x 10^11 Msun from curvature in early-type galaxy scaling relations?
galaxies formation
2010/11/1
For early-type galaxies, the correlations between stellar mass and size, velocity dis-
persion, surface brightness, color, axis ratio and color-gradient all indicate that two mass scales, M∗ = ...
HIFLUGCS: Galaxy cluster scaling relations between X-ray luminosity, gas mass, cluster radius, and velocity dispersion
Cosmology observations (Cosmology:) dark matter Galaxies clusters
2010/11/1
We present relations between X-ray luminosity and velocity dispersion (L − ), X-ray luminosity and gas mass (L − Mgas), and cluster radius and velocity dispersion (r500 − ) for 62 ...
Revisiting with Chandra the Scaling Relations of the X-ray Emission Components (Binaries, Nuclei and Hot Gas) of Early Type Galaxies
galaxies elliptical and lenticular – X-rays galaxies
2010/11/1
We have selected a sample of 30 normal (non-cD) early type galaxies, for all of which optical spectroscopy is available, and which have been observed with Chandra to a depth such to insure the detecti...
