Strong Gravitational Lensing and Microlensing of Supernovae. [PDF]

Space Sci Rev
AbstractStrong gravitational lensing and microlensing of supernovae (SNe) are emerging as a new probe of cosmology and astrophysics in recent years. We provide an overview of this nascent research field, starting with a summary of the first discoveries of strongly lensed SNe. We describe the use of the time delays between multiple SN images as a way to

MOA-2020-BLG-208Lb: Cool Sub-Saturn-mass Planet within Predicted Desert

The Astronomical Journal, 2023
We analyze the MOA-2020-BLG-208 gravitational microlensing event and present the discovery and characterization of a new planet, MOA-2020-BLG-208Lb, with an estimated sub-Saturn mass.

Gravitational Microlensing [PDF]

Proceedings of the International Astronomical Union, 2011
AbstractGravitational microlensing is a well established and unique field of time-domain astrophysics. For two decades microlensing surveys have been regularly observing millions of stars to detect elusive events that follow a characteristic Paczyński lightcurve.

Mass Production of 2021 KMTNet Microlensing Planets II

The Astronomical Journal, 2023
We continue our program of publishing all planets (and possible planets) found by eye in 2021 Korea Microlensing Telescope Network (KMTNet) online data. We present four planets (KMT-2021-BLG-0712Lb, KMT-2021-BLG-0909Lb, KMT-2021-BLG-2478Lb, and KMT-2021 ...

Gravitational microlensing in NUT space [PDF]

Monthly Notices of the Royal Astronomical Society, 2003
We study the theoretical signature of magnetic masses on the light curve of gravitational microlensing effect in NUT space. The light curves for microlensing events in NUT space are presented and contrasted with those due to lensing produced by normal matter. In the next step, associating magnetic mass to massive astrophysical compact objects (MACHOs),
