Search for glitches of gamma-ray pulsars with deep learning

The pulsar glitches are generally assumed to be an apparent manifestation of the superfluid interior of the neutron stars. Most of them were discovered and extensively studied by continuous monitoring in the radio wavelengths. The Fermi-LAT space telescope has made a revolution uncovering a large population of gamma-ray pulsars. In this paper we suggest to employ these observations for the searches of new glitches. We develop the method capable of detecting step-like frequency change associated with glitches in a sparse gamma-ray data. It is based on the calculations of the weighted H-test statistics and glitch identification by a convolutional neural network. The method demonstrates high accuracy on the Monte Carlo set and will be applied for searches of the pulsar glitches in the real gamma-ray data in the future works.Comment: 4 pages, 5 figure

MANTLE-CRUST INTERACTION AT THE LATE STAGE OF EVOLUTION OF HERCYNIAN ALTAI COLLISION SYSTEM, WESTERN PART OF CAOB

Altai collision system of Hercynides was formed in Late Paleozoic as a result of oblique collision of Siberian continent and Kazakhstan composed terrane [Vladimirov et al., 2003; 2008; Xiao et al., 2010]. At the late stages of its evolution (time interval from 310–300 to 280–270 Ma) the huge different mafic and felsic magmatism occurred at the territory (Fig. 1) [Vladimirov et al., 2008; Khromykh et al., 2011, 2013, 2014, 2016; Kotler et al., 2015; Sokolova et al., 2016]. It is evident about increased thermal gradient in lithosphere and about significant role of mantle and active manifestation of mantle-crust interactions. Some magmatic complexes may be considered as indicators of mantle-crust interaction processes.Altai collision system of Hercynides was formed in Late Paleozoic as a result of oblique collision of Siberian continent and Kazakhstan composed terrane [Vladimirov et al., 2003; 2008; Xiao et al., 2010].

Rural Settlement Network in Territory of Contemporary Omsk Region from Last Quarter of 19th Century to Early 20th Century

The article examines the characteristics of the formation of the rural settlement network in the territory of modern Omsk region during the last quarter of the 19th century through the early 20th century. The relevance of this study is driven by societal and governmental interest in rural history, as well as by the expansion of the source base, which is related to the popularization of museum collections and personal archives. Throughout the research, the author analyzes a wide range of sources and identifies features of the territory’s settlement, lifestyle, and everyday life of peasants, as well as the nature of relationships between settlers and natives. The author concludes that natural and geographical conditions played a significant role in shaping the network of rural settlements, organizing economic life, and the daily routines of peasants. Particular attention is paid to the study of the economic life of peasants, as it was one of the defining factors in the formation of the rural settlement network of the territory. The investigation reveals that agriculture was the main occupation for peasants in the Omsk Irtysh region, despite the limited amount of arable land available. Livestock breeding was confined to its economic significance. Additional income for peasants depended on their settlement location and was determined by the natural resources of the territory. Natural and geographical conditions also dictated the external appearance of settlements

Konus-Wind and Helicon-Coronas-F Observations of Solar Flares

Results of solar flare observations obtained in the Konus-Wind experiment from November, 1994 to December, 2013 and in the Helicon Coronas-F experiment during its operation from 2001 to 2005, are presented. For the periods indicated Konus-Wind detected in the trigger mode 834 solar flares, and Helicon-Coronas-F detected more than 300 solar flares. A description of the instruments and data processing techniques are given. As an example, the analysis of the spectral evolution of the flares SOL2012-11-08T02:19 (M 1.7) and SOL2002-03-10T01:34 (C5.1) is made with the Konus-Wind data and the flare SOL2003-10-26T06:11 (X1.2) is analyzed in the 2.223 MeV deuterium line with the Helicon-Coronas-F data.Comment: Published version. A list of the Konus-Wind solar flare triggers and figures of their time profiles are available at http://www.ioffe.ru/LEA/Solar
