First Resolution of Microlensed Images of a Binary-Lens Event

Kavli Affiliate: Jinyi Shangguan | First 5 Authors: Zexuan Wu, Subo Dong, A. Mérand, Christopher S. Kochanek, Przemek Mróz | Summary: We resolve the multiple images of the binary-lens microlensing event ASASSN-22av using the GRAVITY instrument of the Very Large Telescope Interferometer (VLTI). The light curves show weak binary perturbations, complicating the analysis, but the […]

BASS. XLIII: Optical, UV, and X-ray emission properties of unobscured Swift/BAT active galactic nuclei

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 […]
