The twin paradox in the vicinity of rotating black holes
Shuiquan Bai, Geraint F. Lewis
The twin paradox is a foundational thought experiment in the special theory of relativity where a returning twin ages less than the one who remains stationary. However, the intrica…
A Bayesian Exploration of the Mass of Ursa Major III: Kinematics, Rotation and their influence on the Mass to Light Ratio
T. R. Adams, B. J. Brewer, G. F. Lewis
We investigate the kinematics of the potential ultra-faint dwarf galaxy (UFD) UMa III/U1 using Bayesian inference to search for the signal of any potential intrinsic rotation. The…
Rotation of the Globular Cluster Population of the Dark Matter Deficient Galaxy NGC 1052-DF4: Implication for the Total Mass
Yuan Li, Brendon J. Brewer, Geraint F. Lewis
We explore the globular cluster population of NGC 1052-DF4, a dark matter deficient galaxy, using Bayesian inference to search for the presence of rotation. The existence of such a…
Cosmography with the Double Source Plane Strong Gravitational Lens AGEL150745+052256
Nandini Sahu, Anowar J. Shajib, Kim-Vy Tran +14
Strong gravitational lenses with two background sources at widely separated redshifts are a powerful and independent probe of cosmological parameters. We can use these systems, kno…
The AGEL Survey Data Release 2: A Gravitational Lens Sample for Galaxy Evolution and Cosmology
Tania M. Barone, Keerthi Vasan G. C., Kim-Vy Tran +31
The ASTRO 3D Galaxy Evolution with Lenses (AGEL) Survey is an ongoing effort to spectroscopically confirm a diverse sample of gravitational lenses with high spatial resolution imag…
