The road toward imaging a black hole: A personal perspective
Natural Sciences, Volume 2, Issue 4, October 2022., 2022 The article describes the authors personal journey towards developig the Event Horizon Telescope and the first image of a black hole. Left: predcition made by the author and collaborators proposing the black hole imaging in 2000. Right: the two images observed and published by the Event Horizon Telescope in 2019 and 2022.

Identifying interesting planetary systems for future X‐ray observations
Astronomische Nachrichten, Volume 343, Issue 4, May 2022., 2022 Abstract X‐ray observations of star–planet systems are important to grow our understanding of exoplanets; these observations allow for studies of photoevaporation of the exoplanetary atmosphere, and in some cases even estimations of the size of the outer planetary atmosphere.

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.

Strong Gravitational Lensing and Microlensing of Supernovae. [PDF]
Space Sci RevAbstractStrong 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

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),
