The First Dynamical Mass Measurement in the HR 8799 System

G. Mirek Brandt, Timothy D. Brandt, Trent J. Dupuy +2

HR 8799 hosts four directly imaged giant planets, but none has a mass measured from first principles. We present the first dynamical mass measurement in this planetary system, find…

First M87 Event Horizon Telescope Results. VIII. Magnetic Field Structure near The Event Horizon

The Event Horizon Telescope Collaboration

Event Horizon Telescope (EHT) observations at 230 GHz have now imaged polarized emission around the supermassive black hole in M87 on event-horizon scales. This polarized synchrotr…

First M87 Event Horizon Telescope Results. VII. Polarization of the Ring

The Event Horizon Telescope Collaboration

In 2017 April, the Event Horizon Telescope (EHT) observed the near-horizon region around the supermassive black hole at the core of the M87 galaxy. These 1.3 mm wavelength observat…

orvara: An Efficient Code to Fit Orbits using Radial Velocity, Absolute, and/or Relative Astrometry

Timothy D. Brandt, Trent J. Dupuy, Yiting Li +5

We present an open-source Python package, Orbits from Radial Velocity, Absolute, and/or Relative Astrometry (orvara), to fit Keplerian orbits to any combination of radial velocity,…

Constraints on CDM Extensions from the SPT-3G 2018 and Power Spectra

L. Balkenhol, D. Dutcher, P. A. R. Ade +117

We present constraints on extensions to the CDM cosmological model from measurements of the -mode polarization auto-power spectrum and the temperature--mode cross-power sp…

Detection of Galactic and Extragalactic Millimeter-Wavelength Transient Sources with SPT-3G

S. Guns, A. Foster, C. Daley +119

High-angular-resolution cosmic microwave background experiments provide a unique opportunity to conduct a survey of time-variable sources at millimeter wavelengths, a population wh…
