Quantum statistical corrections on the enhancement factor in solar fusion reactions
The enhancement factor to the thermonuclear reaction rate in the center of the Sun is calculated using the Feynman-Kac path integral of the grand-canonical...
Quantum well intermixing in AlInGaAs QW structures through the interdiffusion of group III atoms
In this paper, the composition profiles within intermixed AlInGaAs-based multiple quantum wells structure are analyzed by secondary ion mass spectrometry and...
Quasar clustering at intermediate redshift - Analysis of systematics and of luminosity effects
We measure the clustering of over 55,000 quasars at redshifts 2.2 z 3.4 drawn from the final sample of the Baryonic Oscillation Spectroscopic Survey (BOSS)...
Quasar microlensing in galaxy clusters as a complementary approach to intracluster light
In the gravitational lens SDSS J1004+4112, a background quasar is lensed by a galaxy cluster, hence the light from the quasar images travels mainly through the...
Quasar microlensing: Revolutionizing our understanding of quasar structure and dynamics
Microlensing in strong-lens systems with quasars provides a unique detailed view of the internal structure of active black holes to the scale of nano-...
Most of the questions in this chapter deal with sources that do not show the "classical" broad emission-line spectrum that characterizes the majority of known...
Quasars Do Not Live in Merging Systems: No Enhanced Merger Rate at z≲0.8
We tackle the long-standing question “what is the relevance of major mergers and interactions as triggering mechanisms for AGN activity?” We study a sample of...
