Gravitational Lensing of stars in the central arcsecond of our Galaxy
V. Bozza, L. Mancini
In the neighborhood of Sgr A*, several stars (S2, S12, S14, S1, S8, S13) enjoy an accurate determination of their orbital parameters. General Relativity predicts that the central b…
Microlensing by gas filaments
V. Bozza, L. Mancini
Gas in the interstellar matter is generally organized in filamentary structures, which may be also relevant for a complementary explanation of the dark matter in the Galactic halo.…
Gravitational Lensing by Black Holes: a comprehensive treatment and the case of the star S2
V. Bozza, L. Mancini
Light rays passing very close to a black hole may experience very strong deviations. Two geometries were separately considered in the recent literature: a source behind the black h…
Microlensing towards the Large Magellanic Cloud
Ph. Jetzer, L. Mancini, G. Scarpetta
The nature and the location of the lenses discovered in the microlensing surveys done so far towards the LMC remain unclear. Motivated by these questions we compute the optical dep…
Microlensing by Compact Objects associated to Gas Clouds
V. Bozza, Ph. Jetzer, L. Mancini +1
We investigate gravitational microlensing of point-like lenses surrounded by diffuse gas clouds. Besides gravitational bending, one must also consider refraction and absorption phe…
