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…
