A Distorted Charged Dilaton Black Ring
Shohreh Abdolrahimi, Christos C. Tzounis
We present the distorted five dimensional static black rings in Einstein-Maxwell-dilaton (EMd) gravity by using the sigma model structure of the dimensionally reduced field equatio…
Voyager 3: A Concept Mission to Interstellar Medium
Shohreh Abdolrahimi, Burton Yale, Christos C. Tzounis +5
Voyager 3 is a concept mission that sends a space telescope to the interstellar medium in a reasonable amount of time. Voyager 3 would take a direct image of an exoplanet using the…
A Distorted Black Ring
Shohreh Abdolrahimi, Robert B. Mann, Christos Tzounis
We investigate how a static and neutral distribution of external matter distorts a 5-dimensional static black ring. We obtain a general expression for the distorted metric in terms…
Ingoing Eddington-Finkelstein Metric of an Evaporating Black Hole
Shohreh Abdolrahimi, Don N. Page, Christos Tzounis
We present an approximate time-dependent metric in ingoing Eddington-Finkelstein coordinates for an evaporating nonrotating black hole as a first-order perturbation of the Schwarzs…
Double Images from a Single Black Hole
Shohreh Abdolrahimi, Robert B. Mann, Christos Tzounis
In the simulations of the multi-black holes and merging black holes a larger primary image and a secondary smaller image which looks like an eyebrow and the deformation of the shad…
Properties of the distorted Kerr black hole
Shohreh Abdolrahimi, Jutta Kunz, Petya Nedkova +1
We investigate the properties of the ergoregion and the location of the curvature singularities for the Kerr black hole distorted by the gravitational field of external sources. Th…
Distorted Local Shadows
Shohreh Abdolrahimi, Robert B. Mann, Christos Tzounis
We introduce the notion of a local shadow for a black hole and determine its shape for the particular case of a distorted Schwarzschild black hole. Considering the lowest-order eve…
Production of black holes and string balls in a two-dimensional split-fermion model
Shohreh Abdolrahimi, Christos Tzounis
We present cross-sections for the black hole and string ball production in proton-proton collisions in a TeV-scale gravity model with split fermions in two dimensions. The cross-se…
Radiation from an emitter revolving around a magnetized non-rotating black hole
Valeri P. Frolov, Andrey A. Shoom, Christos Tzounis
One of the methods of study of black holes in astrophysics is based on broadening of the spectrum of radiation of ionized Iron atoms. The line K associated with Iron emission at…
