Kavli Affiliate: Jinyi Shangguan | First 5 Authors: The GRAVITY Collaboration, Karim Abd El Dayem, Roberto Abuter, Nicolas Aimar, Pau Amaro Seoane | Summary: Studying the orbital motion of stars around Sagittarius A* in the Galactic Center provides a unique opportunity to probe the gravitational potential near the supermassive black hole at the heart of […]

Kavli Affiliate: Claudio Ricci | First 5 Authors: Kriti K. Gupta, Claudio Ricci, Matthew J. Temple, Alessia Tortosa, Michael J. Koss | Summary: We present one of the largest multiwavelength studies of simultaneous optical-to-X-ray spectral energy distributions (SEDs) of unobscured active galactic nuclei (AGN) in the local Universe. Using a representative sample of hard-X-ray-selected AGN […]

Kavli Affiliate: Feng Yuan | First 5 Authors: Sijia Peng, Ru-Sen Lu, Ciriaco Goddi, Thomas P. Krichbaum, Zhiyuan Li | Summary: Faraday rotation is an important probe of the magnetic fields and magnetized plasma around active galactic nuclei (AGN) jets. We present a Faraday rotation measure image of the M87 jet between 85.2 GHz and […]

Kavli Affiliate: Lijing Shao | First 5 Authors: Ziming Wang, Yong Gao, Dicong Liang, Junjie Zhao, Lijing Shao | Summary: The recent discovery of gravitational waves (GWs) has opened a new avenue for investigating the equation of state (EOS) of dense matter in compact stars, which is an outstanding problem in astronomy and nuclear physics. […]

Kavli Affiliate: Gregory J. Herczeg | First 5 Authors: Adolfo S. Carvalho, Gregory J. Herczeg, Kevin France, Lynne A. Hillenbrand, | Summary: The eruptive YSO FU Ori is the eponym of its variable class. FU Ori stars are known to undergo outbursts with amplitudes of $>4$ magnitudes in the $V$ band and durations of several […]
