Polarimetry and Astrometry of NIR Flares as Event Horizon Scale, Dynamical Probes for the Mass of Sgr A*

The GRAVITY Collaboration, R. Abuter, N. Aimar +66

We present new astrometric and polarimetric observations of flares from Sgr A* obtained with GRAVITY, the near-infrared interferometer at ESO's Very Large Telescope Interferometer…

Black Holes as Fermion Factories

Yifan Chen, Xiao Xue, Vitor Cardoso

Ultralight bosons near rotating black holes can undergo significant growth through superradiant energy extraction, potentially reaching field values close to the Planck scale and t…

On energy extraction from Q-balls and other fundamental solitons

Vitor Cardoso, Rodrigo Vicente, Zhen Zhong

Energy exchange mechanisms have important applications in particle physics, gravity, fluid mechanics, and practically every field in physics. In this letter we show, both in freque…

Piercing of a solitonic boson star by a black hole

Zhen Zhong, Vitor Cardoso, Taishi Ikeda +1

Recently, the piercing of a mini boson star by a black hole was studied, with tidal capture and the discovery of a "gravitational atom" being reported ( arXiv:2206.00021 [gr-qc] ).…

Spinning Black Holes with Axion Hair

Clare Burrage, Pedro G. S. Fernandes, Richard Brito +1

In this work we construct and analyse non-perturbative stationary and axially-symmetric black hole solutions in General Relativity coupled to an electromagnetic and an axion field.…

Using the motion of S2 to constrain scalar clouds around SgrA*

GRAVITY Collaboration, A. Foschi, R. Abuter +67

The motion of S2, one of the stars closest to the Galactic Centre, has been measured accurately and used to study the compact object at the centre of the Milky Way. It is commonly…
