A remarkable long-term light curve, and deep, low-state spectroscopy: Swift & XMM-Newton monitoring of the NLS1 galaxy Mkn 335
remarkable long-term light curve low-state spectroscopy Swift XMM-Newton monitoring the NLS1 galaxy
2012/2/23
The Narrow-line Seyfert 1 galaxy (NLS1) Mkn 335 is remarkable because it has repeatedly shown deep, long X-ray low-states which show pronounced spectral structure. It has become one of the prototype A...
Spectro-timing analysis of Cygnus X-1 during a fast state transition
X-rays: binaries, X-rays: individual: CygX-1
2011/10/19
We present the analysis of two long, quasi-uninterrupted RXTE observations of Cygnus X-1 that span several days within a 10 d interval. The spectral characteristics during this observation cover the r...
RXTE Observations of the Low-Mass X-Ray Binary 4U 1608-522 in Upper-Banana State
RXTE Observations Low-Mass X-Ray Binary 4U 1608-522 Upper-Banana State
2011/10/11
To investigate the physics of mass accretion onto weakly-magnetized neutron stars, 95 archival RXTE datasets of an atoll source 4U 1608-522, acquired over 1996-2004 in so-called upper-banana state, we...
Spectral and Timing Studies of Cyg X-1 in the Low/Hard State with Suzaku
black hole physics — accretion — stars: individual (Cygnus X-1)—X- ray:binaries
2011/10/11
From 2005 to 2009, 25 observations of Cyg X-1 were performed with Suzaku, achieving a total exposure of 446 ks. In all observations, the source was found in the low/hard state, while the 1.5--12.0 keV...
X-ray spectral state is not correlated with luminosity in Holmberg II X-1
accretion accretion disks – black hole physics – X-rays binaries– X-rays
2010/11/12
The ultraluminous X-ray source (ULX) Holmberg II X-1 has been observed over 4 months in 2009/2010 by the Swift observatory. The source luminosity varied by a factor of up to 14, reaching a maximum 0.3...
Phase transition to the state with nonzero average helicity in dense neutron matter
Phase transition nonzero average dense neutron matter
2010/11/16
The possibility of the appearance of the states with a nonzero average helicity in neutron matter is studied in the model with the Skyrme effective interaction. By providing the analysis of the selfco...
Equation of state for the MCFL phase and its implications for compact star models
High Energy Astrophysical Phenomena (astro-ph.HE)
2011/1/5
Using the solutions of the gap equations of the magnetic-color-flavor-locked (MCFL) phase of paired quark matter in a magnetic field, and taking into consideration the separation between the longitudi...
Generalized equation of state for cold superfluid neutron stars
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/24
Mature neutron stars are expected to contain various kinds of superfluids in their interiors. Modeling such stars requires the knowledge of the mutual entrainment couplings between the different conde...
Resistivity-driven State Changes in Vertically Stratified Accretion Disks
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/22
We investigate the effect of shear viscosity and Ohmic resistivity on the magnetorotational instability (MRI) in vertically stratified accretion disks through a series of local simulations computed wi...
