BOOST -- A Satellite Mission to Test Lorentz Invariance Using High-Performance Optical Frequency References
Norman Gürlebeck, Lisa Wörner, Thilo Schuldt +15
BOOST (BOOst Symmetry Test) is a proposed satellite mission to search for violations of Lorentz invariance by comparing two optical frequency references. One is based on a long-ter…
Photon Regions and Shadows of Accelerated Black Holes
Arne Grenzebach, Volker Perlick, Claus Lämmerzahl
In an earlier paper we have analytically determined the photon regions and the shadows of black holes of the Plebański class of metrics which are also known as the Kerr--Newman--NU…
Aberrational Effects for Shadows of Black Holes
Arne Grenzebach
In this paper, we discuss how the shadow of a Kerr black hole depends on the motion of the observer. In particular, we derive an analytical formula for the boundary curve of the sh…
Photon Regions and Shadows of Kerr-Newman-NUT Black Holes with a Cosmological Constant
Arne Grenzebach, Volker Perlick, Claus Lämmerzahl
We consider the Plebański class of electrovacuum solutions to the Einstein equations with a cosmological constant. These space-times, which are also known as the Kerr-Newman-NUT-(a…
