Two Low-Mass-Ratio Microlensing Planets from High-Magnification Events: KMT-2021-BLG-0247 and MOA-2023-BLG-169
Kansuke Nunota, Andrew Gould, Takahiro Sumi +56
We present an analysis of two planetary microlensing events, KMT-2021-BLG-0247 and MOA-2023-BLG-169, both of which exhibit high magnifications and low planet--host mass ratios, but…
Caustics in gravitational lensing by mixed binary systems
Valerio Bozza, Silvia Pietroni, Chiara Melchiorre
We investigate binary lenses with potentials in the asymmetric case with two lenses with different indexes and . These kinds of potentials have been widely used in s…
A solution to the anisotropy problem in bouncing cosmologies
V. Bozza, M. Bruni
Bouncing cosmologies are often proposed as alternatives to standard inflation for the explanation of the homogeneity and flatness of the universe. In such scenarios, the present co…
A comparison of approximate gravitational lens equations and a proposal for an improved new one
V. Bozza
Keeping the exact general relativistic treatment of light bending as a reference, we compare the accuracy of commonly used approximate lens equations. We conclude that the best app…
Trajectories of the images in binary microlensing
V. Bozza
We study in detail the trajectories followed by single images during binary microlensing events. Starting from perturbative resolutions of the lens equation, we explore the full pa…
Signs of the cusps in binary lenses
Valerio Bozza
The cusps of the caustics of any gravitational lens model can be classified into positive and negative ones. This distinction lies on the parity of the images involved in the creat…
