Horizon-scale variability of M87* from 2017--2021 EHT observations
The Event Horizon Telescope Collaboration
We report three epochs of polarized images of M87* at 230\,GHz using data from the Event Horizon Telescope (EHT) taken in 2017, 2018, and 2021. The baseline coverage of the 2021 ob…
First Sagittarius A* Event Horizon Telescope Results. II. EHT and Multi-wavelength Observations, Data Processing, and Calibration
The Event Horizon Telescope Collaboration
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during th…
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…
X-Ray Polarimetry with the Polarization Spectroscopic Telescope Array (PolSTAR)
Henric S. Krawczynski, Daniel Stern, Fiona A. Harrison +49
This paper describes the Polarization Spectroscopic Telescope Array (PolSTAR), a mission proposed to NASA's 2014 Small Explorer (SMEX) announcement of opportunity. PolSTAR measures…
The Large Observatory for X-ray Timing (LOFT)
M. Feroci, the LOFT Consortium
High-time-resolution X-ray observations of compact objects provide direct access to strong-field gravity, to the equation of state of ultra-dense matter and to black hole masses an…
Spectral Lines from Rotating Neutron Stars
Feryal Ozel, Dimitrios Psaltis
The line profiles from rotating neutron stars are affected by a number of relativistic processes such as Doppler boosts, strong self-lensing, frame-dragging, and the differential g…
