Magneto-rotational and thermal evolution of magnetars with crustal magnetic fields
U. Geppert, D. Page, M. Colpi +1
Soft Gamma-ray Repeaters (SGRs) and Anomalous X-ray Pulsars (AXPs) are interpreted as young highly magnetized neutron stars (NSs). Their X-ray luminosity in quiescence, exceeding 1…

IBM: parameter symmetry, hidden symmetries and transformations of boson operators
A. M. Shirokov, N. A. Smirnova, Yu. F. Smirnov +2
A symmetry of the parameter space of interacting boson models IBM-1 and IBM-2 is studied. The symmetry is associated with linear canonical transformations of boson operators, or, e…

Search for optical microvariability in a large sample of Seyfert I galaxies
P. O. Petrucci, A. Chelli, G. Henri +3
We present results of an optical (I band) monitoring of a sample of 22 Seyfert I galaxies. We aimed to detect microvariability with time resolution from ~ 6 minutes down to 30 seco…
