First detections of CO absorption in the Magellanic Clouds and direct measurement of the CO-to-H ratio
Sergei Balashev, Daria Kosenko, Pasquier Noterdaeme
Molecular hydrogen (H) is by far the most abundant molecule in the Universe. However, due to the low emissivity of H, carbon monoxide (CO) is widely used instead to trace m…
Neutral carbon in diffuse interstellar medium: abundance matching with H2 for DLAs at high redshifts
Sergei Balashev, Daria Kosenko
We present the study of CI/H relative abundance in the diffuse cold neutral medium. Using the chemical and thermal balance model we calculated the dependence of CI/H on the…
Cold diffuse interstellar medium of Magellanic Clouds: I. HD molecule and cosmic-ray ionization rate
D. N. Kosenko, S. A. Balashev
HD molecule is one the most abundant molecule in the Universe and due to its sensibility to the conditions in the medium, it can be used to constrain physical parameters in the med…
Cold diffuse interstellar medium of Magellanic Clouds: II. Physical conditions from excitation of CI and H
D. N. Kosenko, S. A. Balashev, V. V. Klimenko
We present a comprehensive study of the excitation of CI fine-structure levels along 57 sight lines in the Large and Small Magellanic Clouds. The sight lines were selected by the d…
HD molecules at high redshift: cosmic-ray ionization rate in the diffuse interstellar medium
D. N. Kosenko, S. A. Balashev, P. Noterdaeme +3
We present a systematic study of deuterated molecular hydrogen (HD) at high redshift, detected in absorption in the spectra of quasars. We present four new identifications of HD li…
OH in the diffuse interstellar medium: physical modelling and prospects with upcoming SKA precursor/pathfinder surveys
Sergei Balashev, Neeraj Gupta, Daria Kosenko
Hydroxyl () is known to form efficiently in cold gas (K) along with the molecule and can be used as an efficient tracer of the diffuse molecular gas in…
HD/H ratio in the diffuse interstellar medium
S. A. Balashev, D. N. Kosenko
We present a semi-analytical description of the relative HD/H2 abundance in the diffuse interstellar medium. We found three asymptotics of the relative HD/H abundance for diffe…
