Eclipsing negative-parity image of gravitational microlensing by a giant-lens star
Gravitational Microlensing has been used as a powerful tool for astrophysical studies and exoplanet detections. In the gravitational microlensing, we have two images with negative and positive…
Measuring stellar atmosphere parameters using follow-up polarimetric microlensing observations
We present an analysis of the potential follow-up polarimetry microlensing observation to study the stellar atmospheres of the distant stars. First, we produce synthetic microlensing events using the…

In this work, we study detecting free-floating planets (FFPs) by microlensing observations towards the Magellanic Clouds (MCs). In comparison to similar events towards the Galactic bulge, an FFP in…
Microlensing Searches for Exoplanets
Gravitational microlensing finds planets through their gravitational influence on the light coming from a more distant background star. The presence of the planet is then inferred from the tell-tale…

Diffraction-limited 800 nm imaging with the 2.56 m Nordic Optical Telescope
A quantitative assessment is presented of diraction-limited stellar images with Strehl ratios of 0.25{0.30 obtained by selection of short-exposure CCD images of stars brighter than +6 m at 810 nm…
LENS-LIKE ACTION OF A STAR BY THE DEVIATION OF LIGHT IN THE GRAVITATIONAL FIELD.
Some time ago, R. W. Mandi paid me a visit and asked me to publish the results of a little calculation, which I had made at his request. This note complies with his wish.
Adaptive contouring – an efficient way to calculate microlensing light curves of extended sources
The availability of a robust and efficient routine for calculating light curves of a finite source magnified due to bending of its light by the gravitational field of an intervening binary lens is…
The two-colour EMCCD instrument for the Danish 1.54 m telescope and SONG
We report on the implemented design of a two-colour instrument based on electron-multiplying CCD (EMCCD) detectors. This instrument is currently installed at the Danish 1.54 m telescope at ESO’s La…
Lucky imaging: High angular resolution imaging in the visible from the ground
We use a Lucky Imaging system to obtain I -band images with much improved angular resolution on a 2.5 m telescope. We present results from a 10-night assessment campaign on the 2.56 m Nordic Optical…
Composite pictures of selected recentered short exposures to improve the angular resolution
The gain in resolution achieved by selecting frames in a sequence of many short exposures is calculated. The angular resolution as a function of the selection is given. Published values are in good…
MICROLENSING BINARIES DISCOVERED THROUGH HIGH-MAGNIFICATION CHANNEL
Microlensing can provide a useful tool to probe binary distributions down to low-mass limits of binary companions. In this paper, we analyze the light curves of eight binary-lensing events detected…

Flux variations of QSO 0957 + 561 A, B and image splitting by stars near the light path
If the double QSO 0957 + 561 A, B is the result of gravitational lens actions by a massive galaxy, stars in its outer parts and close to the light paths may cause significant flux changes in one…
Ground-based High-Resolution Imaging of Mercury
Images obtained during the 1974–1975 Mariner 10 flybys of Mercury revealed nearly 50% of the surface of the planet at very high spatial resolutions. Since then, Mercury's close proximity to the Sun…
