The Western Jet of SS 433/W50: Hard X-ray Emission, Spectral Evolution, and Comparison to the Eastern Jet
Brydyn Mac Intyre, Samar Safi-Harb, Dmitry Khangulyan +5
The W50 nebula powered by the microquasar SS 433 is a unique laboratory for exploring several fundamental astrophysical phenomena. This study presents observations from NuSTAR and…
Full-polarization millimeter wavelength variability of Sagittarius A* during the 2018 EHT campaign
Ezequiel Albentosa-Ruiz, Jasmin E. Washington, Nicola Marchili +272
Sagittarius A* (Srg A*), the supermassive black hole at the center of the Milky Way, provides a unique laboratory to study accretion dynamics and plasma processes near the event ho…
Duality-Invariant Higher-Derivative Corrections to Charged Stringy Black Holes
Upamanyu Moitra
We study duality-invariant higher-derivative corrections to the charged black hole geometry in two-dimensional heterotic string theory. We illustrate how the conventional perturbat…
A Reverse Black Hole Information Problem
Jan de Boer, Jildou Hollander, Andrew Rolph
We study the formation, detection and coarse-graining of black holes in AdS/CFT, with an emphasis on the tension between boundary unitarity and the production of mixed state Hawkin…
Locating the missing large-scale emission in the jet of M87* with short EHT baselines
Boris Georgiev, Paul Tiede, Sebastiano D. von Fellenberg +280
In Very-Long Baseline Interferometric arrays, nearly co-located stations probe the largest scales and typically cannot resolve the observed source. In the absence of large-scale st…
A universal sum over topologies in 3d gravity
Alexandre Belin, Scott Collier, Lorenz Eberhardt +2
We explore the sum over topologies in AdS quantum gravity and its relationship with the statistical interpretation of the boundary theory. We formulate a statistical version of…
