Exoplanet Searches by Future Deep Space Missions

EPJ Web of Conferences, 2011
The search for exoplanets could benefit from gravitational lensing if we could get to 550 AU from the Sun and beyond. This is because the gravitational lens of the Sun would highly intensify there any weak electromagnetic wave reaching the solar system ...

Galaxy mergers and gravitational lens statistics [PDF]

The Astrophysical Journal, 1994
We investigate the impact of hierarchical galaxy merging on the statistics of gravitational lensing of distant sources. Since no definite theoretical predictions for the merging history of luminous galaxies exist, we adopt a parametrized prescription, which allows us to adjust the expected number of pieces comprising a typical present galaxy at z=0.65.

Liquid Metals as Initiators of Free‐Radical Polymerization of Hydrogels: A Perspective

Advanced Functional Materials, EarlyView.
Gallium‐based liquid metals initiate free radical polymerization to form hydrogels without the use of toxic molecular initiators. In addition to initiating polymerization, they can act as crosslinkers, yielding softer, more extensible, and tougher hydrogels than those formed with conventional initiators.

Gravitational Lens Time Delays Using Polarization Monitoring

Galaxies, 2017
Gravitational lens time delays provide a means of measuring the expansion of the Universe at high redshift (and therefore in the ‘Hubble flow’) that is independent of local calibrations.

IMAGES DISTRIBUTION OF BINARY SYMMETRICAL GRAVITATIONAL LENS

Odessa Astronomical Publications, 2019
In this paper, we study the distribu- tion of images from a point source in N - point gravi- tational lenses. It is well known that in a Schwarzschild lens (N = 1) from a point source, there are always two images.

A Systematic Review of Strong Gravitational Lens Modeling Software

, 2013
Despite expanding research activity in gravitational lens modeling, there is no particular software which is considered a standard. Much of the gravitational lens modeling software is written by individual investigators for their own use.

Inverted PAINT for Material‐Specific Super‐Resolution Fluorescence Imaging of Semiconductors

Advanced Materials, EarlyView.
This study presents Inverted PAINT, a label‐free super‐resolution fluorescence imaging method optimized for thick and non‐transparent semiconductor materials. By employing electrostatic dye–surface interactions in an inverted geometry, the technique enables material‐specific, multicolor, and 3D nanoscale imaging, with applications in semiconductor ...

QUASI-ANALYTICAL METHOD FOR IMAGES CONSTRUCTION FROM GRAVITATIONAL LENSES

Odessa Astronomical Publications, 2016
One of the main problems in the study of system of equations of the gravitational lens, is the computation of coordinates from the known position of the source. In the process of computing finds the solution of equations with two unknowns. The problem is

First Observation of Parallax in a Gravitational Microlensing Event [PDF]

, 1995
We present the first detection of parallax effects in a gravitational microlensing event. Parallax in a gravitational microlensing event observed only from the Earth appears as a distortion of the lightcurve due to the motion of the Earth around the Sun.
