Development of galactic and extragalactic astronomy in Kharkov University [PDF]
Astronomical School’s Report, 2002 Development of investigations in field of galactic and extragalactic in Kharkov University since the moment of their beginnings (from 90th years of XX century) is analyzing. Three periods are distinguished: before the 30th, between 30th and 70th, and after the 70th years of the XX century.

Extragalactic and galactic sources: New evidence, new challenges, new opportunities
EPJ Web of Conferences, 2013 Recent data bring in sharper focus the issue of relative contributions of galactic and extragalactic sources of ultrahigh-energy cosmic rays. On the one hand, there is some new evidence, from gamma-ray observations of blazars, that cosmic rays are ...

The Kinematic Bimodality: Efficient Feedback and Cold Gas Deficiency in Slow-rotating Galaxies
The Astrophysical Journal Letters, 2023 The bimodality in the stellar spin of low-redshift (massive) galaxies, ubiquitously existing at all star formation levels and in diverse environments, suggests that galaxies grow and quench through two diverged evolutionary pathways.

The Supersonic Project: Star Formation in Early Star Clusters without Dark Matter
The Astrophysical Journal Letters, 2023 The formation mechanism of globular clusters (GCs) has long been debated by astronomers. It was recently proposed that supersonically induced gas objects (SIGOs)–which formed in the early Universe due to the supersonic relative motion of baryons and dark

The Low-redshift Lyman Continuum Survey. I. New, Diverse Local Lyman Continuum Emitters
The Astrophysical Journal Supplement Series, 2022 The origins of Lyman continuum (LyC) photons responsible for the reionization of the universe are as of yet unknown and highly contested. Detecting LyC photons from the Epoch of Reionization is not possible due to absorption by the intergalactic medium ...

TeV GAMMA RAYS: OBSERVATIONS VERSUS EXPECTATIONS & THEORY
Acta Polytechnica, 2013 The scope of this paper is to discuss two important questions relevant for TeV γ-ray astronomy; the pursuit to reveal the origin of cosmic rays in our galaxy, and the opacity of the universe in γ-rays.
