Parts-per-million-accurate determination of the K photoionization resonance of Be-like oxygen with resolution of its O-O isotopic shift
Jonas Danisch, Marc Botz, Chintan Shah +15
We determine with high accuracy the energy of the inner-shell transition at…
Possible types of dark matter condensation in embedding gravity
S. A. Paston, A. J. Ziyatdinov
We investigate the possibility of explaining the observed effects usually attributed to the existence of dark matter through a transition from GR to a modified theory of gravity -…
A Bayesian Approach for Strong Field QED Tests with He-like Ions
César Godinho, Jorge Machado, Nancy Paul +3
Detailed comparisons between theory and experiment for quantum electrodynamics (QED) effects in He-like ions have been performed in the literature to search for hints of new physic…
Galaxies decomposition with spiral arms -- II: A multiwavelength case study of M 51
Alexander A. Marchuk, Ilia V. Chugunov, George A. Gontcharov +7
Spiral structure can contribute significantly to a galaxy's luminosity. However, only rarely are proper photometric models of spiral arms used in decompositions. As we show in the…
Isochrone fitting of Galactic globular clusters -- V. NGC6397 and NGC6809 (M55)
George A. Gontcharov, Charles J. Bonatto, Olga S. Ryutina +8
We fit various colour-magnitude diagrams (CMDs) of the Galactic globular clusters NGC\,6397 and NGC\,6809 (M55) by isochrones from the Dartmouth Stellar Evolution Database (DSED) a…
New Interstellar Extinction Maps Based on Gaia and Other Sky Surveys
G. A. Gontcharov, A. A. Marchuk, M. Yu. Khovrichev +5
We present new three-dimensional (3D) interstellar extinction maps in the and Gaia filters within 2 kpc of the Sun, a 3D differential extinction (dust spatial distribution…
The problem of dust attenuation in photometric decomposition of edge-on galaxies and possible solutions
Sergey Savchenko, Denis Poliakov, Aleksandr Mosenkov +6
The presence of dust in spiral galaxies affects the ability of photometric decompositions to retrieve the parameters of their main structural components. For galaxies in an edge-on…
A Three-Dimensional Analytical Model of the Interstellar Extinction within the Nearest Kiloparsec
G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6
We present a new version of our analytical model of the spatial interstellar extinction variations within the nearest kiloparsec. This model treats the 3D dust distribution as a su…
Prospects for future studies using deep imaging: Analysis of individual Galactic cirrus filaments
Anton A. Smirnov, Sergey S. Savchenko, Denis M. Poliakov +6
The presence of Galactic cirrus is an obstacle for studying both faint objects in our Galaxy and low surface brightness extragalactic structures. With the aim of studying individua…
Interstellar Extinction in Galactic Cirri in SDSS Stripe 82
G. A. Gontcharov, A. V. Mosenkov, S. S. Savchenko +6
We have applied the method of star counts with Wolf diagrams to determine the interstellar extinction in five Galactic cirri in Sloan Digital Sky Survey (SDSS) Stripe 82. For this…
The vector form of Kundu-Eckhaus equation and its simplest solutions
Aleksandr O. Smirnov, Aleksandra A. Caplieva
In our work a hierarchy of integrable vector nonlinear differential equations depending on the functional parameter is constructed using a monodromy matrix. The first equation…
Isochrone fitting of Galactic globular clusters -- IV. NGC6362 and NGC6723
George A. Gontcharov, Maxim Yu. Khovritchev, Aleksandr V. Mosenkov +10
We present new isochrone fits to the colour-magnitude diagrams of the Galactic globular clusters NGC\,6362 and NGC\,6723. We utilize 22 and 26 photometric filters for NGC\,6362 and…
The distribution of dust in edge-on galaxies: I. The global structure
Aleksandr V. Mosenkov, Pavel A. Usachev, Zacory Shakespear +9
In this first paper in a series we present a study of the global dust emission distribution in nearby edge-on spiral galaxies. Our sample consists of 16 angularly large and 13 less…
Fundamental Analytic Solutions for the Kulish-Sklyanin Model with Constant Boundary Conditions
Vladimir S. Gerdjikov, Aleksandr O. Smirnov
In the present paper we analyze the construction of fundamental analytic solutions (FAS) for the generalized Kulish-Sklyanin models (KSM) for vanishing (VBC) and constant boundary…
Evolution of dust grain size distribution and grain porosity in galaxies
Hiroyuki Hirashita, Vladimir B. Il'in
The radiative properties of interstellar dust are affected not only by the grain size distribution but also by the grain porosity. We develop a model for the evolution of size-depe…
Fractal dimension of optical cirrus in Stripe82
Alexander A. Marchuk, Anton A. Smirnov, Aleksandr V. Mosenkov +4
The geometric characteristics of dust clouds provide important information on the physical processes that structure such clouds. One of such characteristics is the fractal dim…
Isochrone fitting of Galactic globular clusters -- III. NGC\,288, NGC\,362, and NGC\,6218 (M12)
George A. Gontcharov, Maxim Yu. Khovritchev, Aleksandr V. Mosenkov +6
We present new isochrone fits to colour-magnitude diagrams of the Galactic globular clusters NGC\,288, NGC\,362, and NGC\,6218 (M12). We utilize a lot of photometric bands from the…
