Creation of 2-5 keV and 5-10 keV sky maps using XMM-Newton data

Savchenko, D.O.; Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2014)

Sky maps are powerful visualisation tools for quicklook analysis of extended sources. The latest sky map in soft X-rays (0.1-2.4 keV) has been created in the 1990's using ROSAT data. By analysing publically available data ...
Identification of the ~3.55 keV emission line candidate objects across the sky

Savchenko, D.O.; Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2015)

An emission line at the energy ∼3.55 keV detected in different galaxies and galaxy clusters has caused numerous discussions in high-energy astrophysics and particle physics communities. To reveal the origin of the line, ...
New emission line at ~3.5 keV - observational status, connection with radiatively decaying dark matter and directions for future studies

Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2014)

Recent works of Bulbul et al. (2014) and Boyarsky et al. (2014), claiming the detection of the extra emission line with energy ∼3.5 keV in X-ray spectra of certain clusters of galaxies and nearby Andromeda galaxy, have ...
Observation of the new emission line at ~3.5 keV in X-ray spectra of galaxies and galaxy clusters

Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2016)

The detection of an unidentified emission line in the X-ray spectra of cosmic objects would be a `smoking gun'signature for the particle physics beyond the Standard Model. More than a decade of its extensive searches results ...
Search for cyclotron absorptions from magnetars in the quiescence with XMM-Newton

Malygin, M.G.; Iakubovskyi, D.A. (Advances in Astronomy and Space Physics, 2011)

In this work, we perform the detailed analysis of absorption features in spectra of magnetar candidates observed by XMM-Newton satellite. No significant line-like feature has been found. This negative result may indicate ...
