Gravitational Test Beyond the First Post-Newtonian Order with the Shadow of the M87 Black Hole
Dimitrios Psaltis, Lia Medeiros, Pierre Christian +185
The 2017 Event Horizon Telescope (EHT) observations of the central source in M87 have led to the first measurement of the size of a black-hole shadow. This observation offers a new…
First M87 Event Horizon Telescope Results. I. The Shadow of the Supermassive Black Hole
The Event Horizon Telescope Collaboration
When surrounded by a transparent emission region, black holes are expected to reveal a dark shadow caused by gravitational light bending and photon capture at the event horizon. To…
Probing the high-x content of the nuclei in the fixed-target mode at the LHC
A. Kusina, C. Hadjidakis, D. Kikola +30
Using the LHCb and ALICE detectors in the fixed-target mode at the LHC offers unprecedented possibilities to study the quark, gluon and heavy-quark content of the proton and nuclei…
The Size, Shape, and Scattering of Sagittarius A* at 86 GHz: First VLBI with ALMA
S. Issaoun, M. D. Johnson, L. Blackburn +41
The Galactic Center supermassive black hole Sagittarius A* (Sgr A*) is one of the most promising targets to study the dynamics of black hole accretion and outflow via direct imagin…
The Megamaser Cosmology Project.IX. Black hole masses for three maser galaxies
F. Gao, J. A. Braatz, M. J. Reid +9
As part of the Megamaser Cosmology Project (MCP), we present VLBI maps of nuclear water masers toward five galaxies. The masers originate in sub-parsec circumnuclear disks. For thr…
Real time cosmology - A direct measure of the expansion rate of the Universe
H. -R. Klöckner, D. Obreschkow, C. Martins +6
In recent years cosmology has undergone a revolution, with precise measurements of the microwave background radiation, large galaxy redshift surveys, and the discovery of the recen…
