Luminosity by Attrition [PDF]

open access: yesNature, 1920
WITH reference to Sir Ray Lankester's suggestion in NATURE of November 4 that chemists should endeavour to ascertain the cause of the “empyreumatic” odour which accompanies the flashes of light produced by rubbing two quartz pebbles together, may I suggest also that the inquiry might be extended to include other substances which possess this property ...

The Luminosity Determination [PDF]

open access: yesHighlights of Astronomy, 1995
The Hertzprung-Russel (HR) diagram luminosity calibration relies basically on three kinds of data: trigonometric parallaxes, kinematical data (proper motions and radial velocities) and cluster distances obtained by the zero-age main sequence fitting procedure.

Luminosity and photometry [PDF]

open access: yesProceedings of the Royal Society of London, 1897
The luminosity of the spectrum was determined by what may be term ed the method of the “minimal effective stimulus.” Through the partition separating two dark rooms from each other a hole was drilled 1 mm. across; this was covered with a piece of ground glass.

Luminosity function of GRBs [PDF]

open access: yesAstronomy & Astrophysics, 2001
We attempt to constrain the luminosity function of Gamma Ray Bursts (GRBs) from the observed number count--flux relation and the afterglow redshift data. We assume three classes of luminosity functions for our analysis: (a) Log-normal distribution, (b) Schechter distribution, and (c) Scale-free distribution. We assume several models of the evolution of

The Properties and Luminosity Function of Extremely Low Luminosity Galaxies [PDF]

open access: yesThe Astrophysical Journal, 2005
We examine a sample of low redshift (10 < d < 150 Mpc) galaxies including galaxies with r-band absolute magnitudes as faint as -12.5 (for h=1), selected from the Sloan Digital Sky Survey Data Release 2 (SDSS). The sample is unique in containing galaxies of extremely low luminosities in a wide range of environments, selected with uniform and well ...

Luminosity measurement at ILC [PDF]

open access: yesJournal of Instrumentation, 2013
In this paper we describe a method of luminosity measurement at the future linear collider ILC that estimates and corrects for the impact of the dominant sources of systematic uncertainty originating from the beam-induced effects and the background from physics processes. Based on the relativistic kinematics of the collision frame of the Bhabha process,
