Comparing the Accretion Disk Evolution of Black Hole and Neutron Star X-ray Binaries from Low to Super-Eddington Luminosity
Accretion Disk Evolution Neutron Star X-ray Binaries Super-Eddington Luminosity
2011/10/21
Low-mass X-ray binaries (LMXBs) are systems in which a low-mass companion transfers mass via Roche-lobe overflow onto a black hole (BH) or a weakly magnetized neutron star (NS). It is believed that bo...
Interpreting the Evolution of the Size - Luminosity Relation for Disk Galaxies from Redshift 1 to the Present
galaxies evolution — galaxies formation — methods N-Body simulations
2010/11/9
A sample of very high resolution cosmological disk galaxy simulations is used to investigate the evolution of galaxy disk sizes back to redshift 1 within the CDM cosmology. Artificial images in the r...
The mass-L_x relation for moderate luminosity X-ray clusters
mass-L_x relation moderate luminosity X-ray clusters
2010/11/10
We present measurements of the masses of a sample of 25 moderate X-ray luminosity clusters of galaxies from the 160 square degree ROSAT survey. The masses were obtained from a weak lensing analysis of...
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
2010/11/15
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 − )...
X-ray spectral state is not correlated with luminosity in Holmberg II X-1
accretion accretion disks – black hole physics – X-rays binaries– X-rays
2010/11/12
The ultraluminous X-ray source (ULX) Holmberg II X-1 has been observed over 4 months in 2009/2010 by the Swift observatory. The source luminosity varied by a factor of up to 14, reaching a maximum 0.3...
Reexamination of a Bound on the Dirac Neutrino Magnetic Moment from the Supernova Neutrino Luminosity
Reexamination of a Bound Neutrino Magnetic Moment Supernova Neutrino Luminosity
2010/11/12
We investigate the neutrino helicity-flip process under supernova core conditions, where the left-handed neutrinos being produced can be converted into right-handed neutrinos sterile with respect to t...
On the Origin of Ultraviolet Emission and the Accretion Model of Low-luminosity AGNs
accretion accretion disks — black hole physics — galaxies active — quasars general — Ultraviolet general
2010/11/12
Low-luminosity active galactic nuclei (LLAGNs) are generally believed to be powered by an inner radiatively inefficient, advection-dominated accretion flow (ADAF), an outer truncated thin disk, and a ...
Common Powering Mechanism of Intermediate Luminosity Optical Transients and Luminous Blue Variables
winds outflows— stars mass loss— stars vari-ables other — supernovae general
2010/11/11
We study recent Intermediate Luminosity Optical Transients (ILOTs) and major eruptions of Luminous Blue Variables (LBVs), and strengthen claims for a similar powering mechanism. We study new ILOTs and...
