On Black Hole Area Quantization and Echoes
Andrew Coates, Sebastian H. Völkel, Kostas D. Kokkotas
In this work we argue that black hole area quantization of Bekenstein and Mukhanov should not give rise to measurable effects in terms of so-called gravitational wave echoes during…
Instability of vectorized stars
Ekrem S. Demirboğa, Andrew Coates, Fethi M. Ramazanoğlu
In recent papers it has been shown that a large class of vectorization mechanisms in gravity, which involve the vector fields becoming apparently tachyonic in some regime, are actu…
The ghost of vector fields in compact stars
Hector O. Silva, Andrew Coates, Fethi M. Ramazanoğlu +1
Spontaneous scalarization is a mechanism that allows a scalar field to go undetected in weak gravity environments and yet develop a nontrivial configuration in strongly gravitating…
Jupiter's X-ray aurora during UV dawn storms and injections as observed by XMM-Newton, Hubble, and Hisaki
A. D. Wibisono, G. Branduardi-Raymont, W. R. Dunn +9
We present results from a multiwavelength observation of Jupiter's northern aurorae, carried out simultaneously by XMM-Newton, the Hubble Space Telescope (HST), and the Hisaki sate…
Titan: Earth-like on the Outside, Ocean World on the Inside
Shannon M. MacKenzie, Samuel P. D. Birch, Sarah Horst +30
Thanks to the Cassini-Huygens mission, Titan, the pale orange dot of Pioneer and Voyager encounters has been revealed to be a dynamic, hydrologically-shaped, organic-rich ocean wor…
The gravitational Higgs mechanism and resulting smoking gun effects
Verena Krall, Andrew Coates, Kostas D. Kokkotas
Recently, a toy model was introduced to demonstrate that screening mechanisms in alternative theories of gravitation can hide additional effects. In this model a scalar field is ch…
