Discerning Parallax Amplitude in Astrometric Microlensing
Sedighe Sajadian, Arya Mahmoudzadeh, Setareh Moein
Gravitational microlensing is a powerful method for discovering Isolated Stellar-Mass Black Holes(ISMBHs). These objects make long-duration microlensing events. To characterize the…
Detecting isolated stellar-mass black holes by the Roman telescope
Sedighe Sajadian, Kailash C. Sahu
Isolated Stellar-Mass BlackHoles (ISMBHs) are potentially discernible through microlensing observations. In this work, we study detecting and characterizing ISMBHs with the Roman o…
A Statistical Relation between Mass, Age and Velocity Dispersion in the Solar Neighborhood
Hossein Fatheddin, Sedighe Sajadian
The stellar kinematics of the Galactic disk are main factors for constraining disk formation and evolution processes in the Milky Way (MW) Galaxy. In this paper we investigate a st…
Understanding EROS2 observations toward the spiral arms within a classical Galactic model framework
Marc Moniez, Sedighe Sajadian, Mansour Karami +2
EROS has searched for microlensing toward four directions in the Galactic plane away from the Galactic center. The interpretation of the catalog optical depth is complicated by the…
Simulation of a strategy for the pixel lensing of M87 using the Hubble Space Telescope
Sedighe Sajadian, Sohrab Rahvar
In this work, we propose a new strategy for the pixel-lensing observation of M87 in the Virgo cluster using the {\it Hubble Space Telescope} (HST). In contrast to the previous obse…
