We and Universe - before and after 2020

The Nobel Prize in Physics 2020 has been shared by Roger Penrose, Reinhard Genzel, and Andrea Ghez. Roger Penrose received it “for the discovery that black hole formation is a robust prediction of the general theory of relativity”. Roger Penrose pioneered a new way of studying General Relativity, which clarified the fact that Black Holes are not just solutions of the theory but the consequence of gravitational collapse. Therefore they must be ubiquitous objects in our Universe.

On the other hand, Reinhard Genzel and Andrea Ghez received The Nobel Prize in Physics 2020 “for the discovery of a supermassive compact object at the center of our galaxy”. The recent observations by the LIGO gravitational wave detector convinced the existence of Black Holes (Rainer Weiss, Barry C. Barish, and Kip S. Thorne – The Nobel Prize in Physics 2017). However, the monitoring stars orbiting the region of Sagittarius A* already led to the conclusion that there must be a supermassive black hole pulling those stars into such orbits. In other words, the observations of the Galactic Center made since the early 1990s by their research groups are the first and the most convincing observational evidence of the existence of Black Holes.

The work in both directions certainly improved our understanding of the Universe. However, alternative possibilities still have been left unexplored or not well explored. Definitely, work in this direction will be a new Nobel Prize in Physics.

Martiros Khurshudyan

Martiros Khurshudyan, male, was born in Yerevan, Armenia on 21 April 1985. He obtained a bachelor’s and master’s degrees in theoretical physics from Yerevan State University, Armenia. In 2017 he obtained his PhD in theoretical physics from Tomsk State University, Tomsk, Russia.
Since 2008 September Dr. Martiros Khurshudyan was working as a researcher on cosmology and astrophysics at different institutions in Italy, Germany, France, Poland, Russia, and Armenia. He is the author of more than 50 papers in cosmology addressing different problems of the field, being in a collaboration with different groups in Italy, Spain, China, Japan, Norway, and Russia.
Thanks to the „Chinese Academy of Sciences Presidents International Fellowship Initiative Grant” he joined to the University of Science and Technology of China in April 2018 for the second postdoc term. The first postdoc he had immediately after the PhD defence at TUSUR, Tomsk, Russia. In April 2019 he joined to the Institute of Space Sciences, CSIC, in Barcelona for another postdoc term.
He continues his research in cosmology and astrophysics at the Cosmology and Fundamental Physics department at the Institute of Space Sciences.

Prof. Martiros Khurshudyan wygrał konkurs na stanowisko profesora w Instytucie Fizyki Uniwersytetu Śląskiego. Zatrudnienie planowane jest od lutego 2021 roku.
