Precision luminosity measurements at LHCb [PDF]

Journal of Instrumentation, 2014
Measuring cross-sections at the LHC requires the luminosity to be determined accurately at each centre-of-mass energy √s. In this paper results are reported from the luminosity calibrations carried out at the LHC interaction point 8 with the LHCb ...

Gamma-ray Burst Luminosity Relations: Two-dimensional versus Three-dimensional Correlations [PDF]

Astrophys.J.705:L15-L19, 2009, 2009
The large scatters of luminosity relations of gamma-ray bursts (GRBs) have been one of the most important reasons that prevent the extensive applications of GRBs in cosmology. In this paper, we extend the two-dimensional (2D) luminosity relations with $\tau_{\mathrm{lag}}$, $V$, $E_{\mathrm{peak}}$, and $\tau_{\mathrm{RT}}$ as the luminosity indicators

The Empirical Mass-Luminosity Relation for Low Mass Stars [PDF]

Astrophys.SpaceSci.314:51-58,2008, 2007
This work is devoted to improving empirical mass-luminosity relations and mass-metallicity-luminosity relation for low mass stars. For these stars, observational data in the mass-luminosity plane or the mass-metallicity-luminosity space subject to non-negligible errors in all coordinates with different dimensions.

Supermassive Black Holes in the Hierarchical Universe: A General Framework and Observational Tests [PDF]

Astrophys.J.704:89-108,2009, 2009
(Abridged) We present a simple framework for the growth and evolution of supermassive black holes (SMBHs) in the hierarchical structure formation paradigm. In our model, black hole accretion is triggered during major mergers (mass ratio>~0.3) between host dark matter halos. The successive evolution of quasar luminosities follows a universal light curve

The Galaxy Luminosity Function and Luminosity Density at Redshift z=0.1 [PDF]

, 2002
Using a catalog of 147,986 galaxy redshifts and fluxes from the Sloan Digital Sky Survey (SDSS), we measure the galaxy luminosity density at z = 0.1 in five optical bandpasses corresponding to the SDSS bandpasses shifted to match their rest-frame shape ...

Characterizing the luminosity components of luminous infrared galaxies in multi-wavelength from the X-ray to the far-infrared [PDF]

Scientific Reports
We characterize luminosity components of Ultra/Luminous Infrared Galaxies (U/LIRGs) in multi-wavelength from the X-ray to far-infrared. A set of 63 AGN U/LIRGs was selected where these galaxies are powered by a central active galactic nucleus (AGN ...
