Analytical solutions for timelike orbits around Damour-Solodukhin wormholes
Shao-Chen Ho, Yo-Chung Ko, Tien Hsieh +1
We investigate timelike geodesics around Damour-Solodukhin wormholes, which are Schwarzschild-like geometries characterized by a deformation parameter that determines the radiu…

A JWST View of the Overmassive Black Hole in NGC 4486B
Behzad Tahmasebzadeh, Matthew A. Taylor, Monica Valluri +19
We present a new stellar dynamical measurement of the supermassive black hole (SMBH) in the compact elliptical galaxy NGC 4486B, based on integral field spectroscopy with JWST/NIRS…

A Supermassive Black Hole in a Diminutive Ultra-compact Dwarf Galaxy Discovered with JWST/NIRSpec+IFU
Matthew A. Taylor, Behzad Tahmasebzadeh, Solveig Thompson +18
The integral-field unit mode of the Near-Infrared Spectrograph (NIRSpec+IFU) mounted on the James Webb Space Telescope has now enabled kinematic studies of smaller and less massive…
