Is Quantum Suicide Painless? On an Apparent Violation of The Principal Principle
Milan M. Cirkovic
The experimental setup of the self-referential quantum measurement, jovially known as the "quantum suicide" or the "quantum Russian roulette" is analyzed from the point of view of…
Massive star-formation rates of gamma-ray burst host galaxies: an unobscured view in X-rays
D. Watson, J. Hjorth, P. Jakobsson +3
The hard X-ray (2-10keV) luminosity of a star-forming galaxy tracks its population of high mass X-ray binaries and is essentially unobscured. It is therefore a practically unbiased…
The Lyman-alpha glow of gas falling into the dark matter halo of a z=3 galaxy
Michael Weidinger, Palle Moller, Johan P. U. Fynbo
Quasars are the visible signatures of super-massive black holes in the centres of distant galaxies. It has been suggested that quasars are formed during ``major merger events'' whe…
The line-of-sight towards GRB 030429 at z = 2.66: Probing the matter at stellar, galactic and intergalactic scales
P. Jakobsson, J. Hjorth, J. P. U. Fynbo +21
We report the discovery of the optical afterglow (OA) of the long-duration gamma-ray burst GRB 030429, and present a comprehensive optical/near-infrared dataset used to probe the m…
Three's a Crowd: On Causes, Entropy, and Physical Eschatology
Milan M. Cirkovic, Vesna Milosevic-Zdjelar
Recent discussions of the origins of the thermodynamical asymmetry ("the arrow of time") by Huw Price and others are critically assessed. This serves as a motivation for considerat…
Searches of stellar mass dark matter from an analysis of variabilities of high red-shifted QSOs
A. F. Zakharov, L. C. Popovic, P. Jovanovic
We consider a contribution of microlensing to the X-ray variability of high-redshifted QSOs. Such an effect could be caused by stellar mass objects (SMO) located in a bulge or/and…
