OGLE-2014-BLG-1186: gravitational microlensing providing evidence for a planet orbiting the foreground star or for a close binary source?
M. Dominik, E. Bachelet, V. Bozza +40
(abridged) Using the particularly long gravitational microlensing event OGLE-2014-BLG-1186 with a time-scale ~ 300 d, we present a methodology for identifying the na…
Propagation of Electromagnetic Waves in MOG: Gravitational Lensing
S. Rahvar, J. W. Moffat
We investigate the solution of Maxwell's equations in curved spacetime within the framework of Modified Gravity (MOG). We show that besides the null-geodesic treatment of photons i…
Microlensing Parallax for OGLE-2017-BLG-0896 Reveals a Counter-Rotating Low-Mass Brown Dwarf
Yossi Shvartzvald, Jennifer C. Yee, Jan Skowron +63
The kinematics of isolated brown dwarfs in the Galaxy, beyond the solar neighborhood, is virtually unknown. Microlensing has the potential to probe this hidden population, as it ca…
OGLE-2017-BLG-0329L: A Microlensing Binary Characterized with Dramatically Enhanced Precision Using Data from Space-based Observations
C. Han, S. Calchi Novati, A. Udalski +54
Mass measurements of gravitational microlenses require one to determine the microlens parallax $\pie$, but precise $\pie$ measurement, in many cases, is hampered due to the subtlet…
The Excursion set approach: Stratonovich approximation and Cholesky decomposition
Farnik Nikakhtar, Mohammadreza Ayromlou, Shant Baghram +3
The excursion set approach is a framework for estimating how the number density of nonlinear structures in the cosmic web depends on the expansion history of the universe and the n…
