Structure of Kerr black hole spacetimes in Weyl conformal gravity

Miguel Yulo Asuncion, Keith Horne, Reinosuke Kusano +1

We analyze the stationary, uncharged, rotating, vacuum solution to Weyl conformal gravity. We elucidate the causal and ergoregion structure of the spacetimes found in the parameter…

Digging deeper into the dense Galactic globular cluster Terzan 5 with Electron-Multiplying CCDs. Variable star detection and new discoveries

R. Figuera Jaimes, M. Catelan, K. Horne +20

Context. High frame-rate imaging was employed to mitigate the effects of atmospheric turbulence (seeing) in observations of globular cluster Terzan 5. Aims. High-precision time-ser…

AGN STORM 2. VI. Mapping Temperature Fluctuations in the Accretion Disk of Mrk 817

Jack M. M. Neustadt, Christopher S. Kochanek, John Montano +49

We fit the UV/optical lightcurves of the Seyfert 1 galaxy Mrk 817 to produce maps of the accretion disk temperature fluctuations resolved in time and radius. The maps are…

TESS Spots a Super-Puff: The Remarkably Low Density of TOI-1420b

Stephanie Yoshida, Shreyas Vissapragada, David W. Latham +51

We present the discovery of TOI-1420b, an exceptionally low-density ( g cm) transiting planet in a day orbit around a late G dwarf star. Using tra…

OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf

Shota Miyazaki, Takahiro Sumi, David P. Bennett +92

We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…

OGLE-2015-BLG-1649Lb: A gas giant planet around a low-mass dwarf

Masayuki Nagakane, Chien-Hsiu Lee, Naoki Koshimoto +66

We report the discovery of an exoplanet in microlensing event OGLE-2015-BLG-1649. The planet/host-star mass ratio is and the projected separation normalized…
