The Nearby Supernova Factory
W. M. Wood-Vasey, G. Aldering, B. C. Lee +19
The Nearby Supernova Factory (SNfactory) is an ambitious project to find and study in detail approximately 300 nearby Type Ia supernovae (SNe~Ia) at redshifts 0.03<z<0.08. This pro…
From quantum Bayesian inference to quantum tomography
R. Derka, V. Buzek, G. Adam +1
We derive an expression for a density operator estimated via Bayesian quantum inference in the limit of an infinite number of measurements. This expression is derived under the ass…
MIFS: A Mega Integral Field Spectrograph for the VLT
R. Bacon, G. Adam, S. Cabrit +14
We describe MIFS, a second generation integral-field spectrograph for the VLT, operating in the visible wavelength range. It combines a 1'x1' field of view with the improved spatia…
Computationally efficient analytic representation of relativistic transition matrix elements in the Lamb shift calculations for hydrogenic atoms
J. Seke, A. V. Soldatov, M. Polak +1
By using the plane-wave expansion for the electromagnetic-field vector potential, transition matrix elements between the relativistic bound and unbound states of hydrogenic atoms w…
Correlation between the gamma-ray and the radio emissions
J. H. Fan, G. Adam, G. Z. Xie +3
In this paper, the correlation between the gamma-ray and the radio bands is investigated. The results show that there is a closer correlation between the gamma-ray emission and the…
Reconstruction of quantum states of spin systems via the Jaynes principle of maximum entropy
V. Buzek, G. Drobny, G. Adam +2
We apply the Jaynes principle of maximum entropy for the partial reconstruction of correlated spin states. We determine the minimum set of observables which are necessary for the c…
Long-term Variation of AGNs
J. H. Fan, G. Z. Xie, G. Adam +5
In this paper, we will discuss the long-term variations in the optical and the infrared bands of some AGNs. It is interesting to note that the reported periods of AGNs are of the s…
Quantum State Reconstruction From Incomplete Data
V. Buzek, G. Drobny, R. Derka +2
Knowing and guessing, these are two essential epistemological pillars in the theory of quantum-mechanical measurement. As formulated quantum mechanics is a statistical theory. In g…
The infrared and optical variability of OJ 287
J. H. Fan, G. Adam, G. Z. Xie +7
In this paper, the long-term historical optical (UBVRI) and near-infrared (JHK) data are presented with some new observations in the optical (February 1994-January 1995) and near-i…
