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.

Effervescence‐Inspired Self‐Healing Plastrons for Long‐Term Immersion Stability
Advanced Functional Materials, Volume 32, Issue 4, January 19, 2022., 2022 Underwater performance of superhydrophobic/superamphiphobic surfaces relies on the robustness and durability of the gas‐layer (plastron). A simple and scalable technique of effervescence‐inspired on‐demand plastron repair is presented. Surfaces do not suffer from any performance‐losses even after 2 months of continuous immersion.

Comparison of Rutherford's atomic model with the Standard Model of particle physics and other models
Journal of the Royal Society of New Zealand, Volume 51, Issue 3-4, Page 538-556, September ‐ December 2021., 2021 ABSTRACT Ernest Rutherford is known almost universally as the discoverer of the structure of the atom. He is less well known for his discovery of the proton. Even less well known is a set of hypotheses on the structure of matter that was proposed by Newton 300 years ago.

The Fundamental Connections between the Solar System and Exoplanetary Science
Journal of Geophysical Research: Planets, Volume 126, Issue 2, February 2021., 2021 Abstract Over the past several decades, thousands of planets have been discovered outside our Solar System. These planets exhibit enormous diversity, and their large numbers provide a statistical opportunity to place our Solar System within the broader context of planetary structure, atmospheres, architectures, formation, and evolution.

A Relativistic Compact Stellar Model of Anisotropic Quark Matter Mixed with Dark Energy
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The possibility of strange stars mixed with dark energy to be one of the candidates for dark energy stars is the main issue of the present study. Our investigation shows that quark matter atcs as dark energy after a certain yet unknown critical condition inside the quark stars.

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),

Gravitational Microlensing [PDF]
Naturwissenschaften, 1999 Gravitational lensing - i.e. light deflection by gravity - has become an important tool for exploring our Universe, in particular to determine its matter content. There are cases in which the deflection angles are tiny, of the order of milliarcseconds or smaller, such that the multiple images are not observable.
