Analysis of the broad-band emission from the baseline model revealed that it reasonably describes the spectral energy distribution (SED) of 6 galaxies. The best SEDs were obtained for the following galaxies: CGCG248-019 (χ2=1.6), CGCG179-005 (χ2=1.6), CGCG243-024 (χ2=2.6), IC0009 (χ2=2.8), MCG+09-25-022 (χ2=31), and UGC10244 (χ2=4.1). The contribution to radiation from the active nucleus was estimated for 15 galaxies, revealing that it does not exceed 10%. This finding is consistent with the previous assumption that the activity of the cores of the most isolated galaxies is weak. However, this assumption does not hold for several objects, including UGC01597, NGC7479, NC5231, and NGC4395, as they exhibit hard X-ray emission according to data from the Swift/BAT catalog, with luminosities ranging from 10^42 to 10^44 erg/s.Panoramic spectral observations (Integral Field Units, IFU) of the dwarf irregular galaxy NGC 1569 were conducted as part of the Metal-THINGS project. Observations took place at the McDonald Observatory (Texas) using the 2.7-meter Harlan Schmidt telescope equipped with the George Mitchell spectrograph (VIRUS-P). Optical observations were supplemented by observations of this galaxy in other spectral ranges obtained from the THINGS, CARMA, and DustPedia surveys, enabling the mapping of various characteristics such as oxygen content, surface density of dust, gas and stars, and rate of star formation.The study of selected celestial objects within the Galaxy was conducted using observation complexes and networks of the MAO of the National Academy of Sciences of Ukraine."  Product Description popup.authors Andreev Maksym V.
