Event Horizon Telescope observations of the jet launching and collimation in Centaurus A
Michael Janssen, Heino Falcke, Matthias Kadler +236
Very-long-baseline interferometry (VLBI) observations of active galactic nuclei at millimeter wavelengths have the power to reveal the launching and initial collimation region of e…
The Variability of the Black-Hole Image in M87 at the Dynamical Time Scale
Kaushik Satapathy, Dimitrios Psaltis, Feryal Ozel +235
The black-hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center o…
Observational search for primordial chirality violations using galaxy angular momenta
Pavel Motloch, Ue-Li Pen, Hao-Ran Yu
We search for evidence of primordial chirality violation in the galaxy data from the Sloan Digital Sky Survey by comparing how strongly directions of galaxy angular momenta correla…
Correlating galaxy shapes and initial conditions: an observational study
Pavel Motloch, Ue-Li Pen, Hao-Ran Yu
Using data from the Sloan Digital Sky Survey we study correlations between directions of galaxy angular momenta determined from images of spiral galaxies and various observables de…
Measuring lens dimensionality in extreme scattering events through wave optics
Dylan L. Jow, Ue-Li Pen
Compact radio sources have been observed to undergo large, frequency dependent changes in intensity due to lensing by structures in the interstellar medium, in so-called "extreme s…
Cosmic Tidal Reconstruction with Halo Fields
Hong-Ming Zhu, Tian-Xiang Mao, Ue-Li Pen
The gravitational coupling between large-scale perturbations and small-scale perturbations leads to anisotropic distortions of the small-scale matter distribution. The measured loc…
