Joint spectral-timing modelling of the hard lags in GX 339-4: constraints on reflection models
Joint spectral-timing modelling the hard lags GX 339-4 constraints reflection models
2012/2/23
The X-ray variations of hard state black hole X-ray binaries above 2 keV show 'hard lags', in that the variations at harder energies follow variations at softer energies, with a time-lag \tau dependin...
Significance of tension for gravitating masses in Kaluza-Klein models
Significance tension gravitating masses Kaluza-Klein models
2012/2/23
In this report, we consider the six-dimensional Kaluza-Klein models with spherical compactification of the internal space. Here, we investigate the case of bare gravitating compact objects with the du...
Spectral-Temporal Simulations of Internal Dissipation Models of Gamma-Ray Bursts
Spectral-Temporal Simulations Internal Dissipation Models Gamma-Ray Bursts
2011/10/19
We present calculations of the time evolution of the prompt spectra of gamma-ray burst models involving generic internal dissipation regions, including internal shocks, either by itself or in the pres...
Unification models with reheating via Primordial Black Holes
Unification models reheating via Primordial Black Holes
2011/10/20
We study the possibility of reheating the universe through the evaporation of Primordial Black Holes created at the end of inflation. This is shown to allow for the unification of inflation and dark m...
Characters of current type Ia supernovae data based on evolving dark energy models
dark energy theory supernova type Ia - standard candles cosmological param-eters from CMBR
2010/11/11
We study characters of recent type Ia supernova (SNIa) data using evolving dark energy models with changing equation of state parameter w. We consider sudden-jump approximation of w for some chosen re...
p, He, and C to Fe cosmic-ray primary fluxes in diffusion models: Source and transport signatures on fluxes and ratios
Methods statistical – ISM cosmic rays
2010/11/10
Context. The source spectrum of cosmic rays is not well determined by diffusive shock acceleration models. The prop-agated fluxes of proton, helium, and heavier primary cosmic-ray species (up to Fe) a...
Hadronic jet models today

2010/11/10
The matter content of relativistic jets in AGNs is dominated by a mixture of protons,
electrons, and positrons. During dissipative events these particles tap a significant portion of the internal and...
Evidence for Low Black Hole Spin and Physically Motivated Accretion Models from Millimeter VLBI Observations of Sagittarius A*
black hole physics—Galaxy center—techniques interferometric—submillimeter—accretion accretion
2010/11/15
Millimeter very-long baseline interferometry (mm-VLBI) provides the novel capacity to probe the emission region of a handful of supermassive black holes on sub-horizon scales. For Sagittarius A* (Sgr ...
Type Ia Supernova Delay Times and Rates for Sub-Chandrasekhar Mass Models
binaries close – stars evolution supernovae white dwarfs
2010/11/11
We present theoretical delay time distributions and rates of Type Ia SNe from the formation channels that are thought to lead to Type Ia supernovae, including the sub-Chandrasekhar mass model, using t...
Abundance Patterns in S-type AGB stars : Setting Constraints on Nucleosynthesis and Stellar Evolution Models
Abundance Patterns Setting Constraints Stellar Evolution Models
2010/11/12
During the evolution on the AGB, S-type stars are the first objects to experience s-process nucleosynthesis and third dredge-ups, and therefore to exhibit sprocess signatures in their atmospheres.
The baroclinic instability in the context of layered accretion. Self-sustained vortices and their magnetic stability in local compressible unstratified models of protoplanetary disks
baroclinic instability magnetic stability protoplanetary disks
2010/11/10
Context. Turbulence and angular momentum transport in accretion disks remain a topic of debate. With the realization that dead zones are robust features of protoplanetary disks, the search for hydrody...

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...

2010/12/27
The WILLI detector, built in IFIN-HH Bucharest, in collaboration with KIT Karlsruhe, is a rotatable modular detector for measuring charge ratio for cosmic muons with energy $<$ 1 GeV. It is under cons...
