A Reflection Model with a Radial Disk Density Profile
نویسندگان
چکیده
In this paper we present RELXILLDGRAD_NK, a relativistic reflection model in which the electron density of accretion disk is allowed to have radial power-law profile. The ionization parameter has also non-constant profile and calculated self-consistently from emissivity. We show impact implementation gradient our by analyzing NuSTAR spectrum Galactic black hole EXO 1846-031 during its last outburst 2019 putative future observation same source with Athena eXTP. For spectrum, find that new provides better fit, but there no significant difference estimation parameters. Athena+eXTP simulation, without unsuitable test spacetime metric around compact object, sense modeling uncertainties can incorrectly lead finding non-vanishing deformation Kerr solution.

a comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
15 صفحه اولA Non-radial rough DEA model
For efficiency evaluation of some of the Decision Making Units that have uncertain information, Rough Data Envelopment Analysis technique is used, which is derived from rough set theorem and Data Envelopment Analysis (DEA). In some situations rough data alter nonradially. To this end, this paper proposes additive rough–DEA model and illustrates the proposed model by a numerical example.
متن کاملA NON-RADIAL ROUGH DEA MODEL
There are situations that Decision Making Units (DMU’s) have uncertain information and their inputs and outputs cannot alter redially. To this end, this paper combines the rough set theorem (RST) and Data Envelopment Analysis (DEA) and proposes a non-redial Rough-DEA (RDEA) model so called additive rough-DEA model and illustrates the proposed model by a numerical example.
متن کاملRadial Disk Heating by More than One Spiral Density Wave
We consider a differentially rotating, 2D stellar disk perturbed by two steady state spiral density waves moving at different patterns speeds. Our investigation is based on direct numerical integration of initially circular test-particle orbits. We examine a range of spiral strengths and spiral speeds and show that stars in this time dependent gravitational field can be heated (their random mot...
متن کاملA novel radial super-efficiency DEA model handling negative data
Super-efficiency model in the presence of negative data is a relatively neglected issue in the DEA field. The existing super-efficiency models have some shortcomings in practice. In this paper, a novel VRS radial super-efficiency DEA model based on Directional Distance Function (DDF) is proposed to provide a complete ranking order of units (including efficient and inefficient ones). The propose...
