Irreversibility of time in general relativity [PDF]
Известия Саратовского университета. Новая серия: Физика, 2022 Background and Objectives: The equations of classical dynamics of particles and waves admit solutions with the reverse flow of time. Therefore, it is generally assumed that classical dynamics does not reflect the irreversibility of time.

The total mass of the early-type galaxy NGC 4649 (M60) [PDF]
Serbian Astronomical Journal, 2008 In this paper the problem of the total mass and the total mass-to-light ratio of the early-type galaxy NGC 4649 (M60) is analyzed. Use is made of two independent techniques: the X-ray methodology which is based on the temperature of the X-ray halo of NGC

Gravitation waves from QCD and electroweak phase transitions [PDF]
Journal of High Energy Physics, 2017 We investigate the gravitation waves produced from QCD and electroweak phase transitions in the early universe by using a 5-dimension holographic QCD model and a holographic technicolor model.

Parcours, pratique théorique et documents scientifiques « privés » du physicien Jacques Solomon
Comptes Rendus. Physique, 2022 Jacques Solomon (1908-1942) is an important figure in the theoretical physics of the 1930s in France. His published works and the personal documents that have been entrusted to me, reveal specific writing processes and theoretical elaborations, which his

Symposium - International Astronomical Union, 1993 In approximately half the systems currently recognized as strongly gravitationally lensed, the background object is an extragalactic radio source. Radio observations have played an important role in the identification of lensed systems, and the properties of radio sources allow some of the astrophysical applications of lensing to be realized.

On the invisibility and impact of Robert Hooke’s theory of gravitation
Open Philosophy, 2020 Robert Hooke’s theory of gravitation is a promising case study for probing the fruitfulness of Menachem Fisch’s insistence on the centrality of trading zone mediators for rational change in the history of science and mathematics.
