Methanol isotopologues as a probe for spatial and temporal variations of the electron-to-proton mass ratio
J. S. Vorotyntseva, M. G. Kozlov, S. A. Levshakov
We present results on numerical calculations of the sensitivity coefficients, Qmu, of microwave molecular transitions in (13C)H3OH and CH3(18O)H to the hypothetical variation in th…
Collisional Pumping of HO and CHOH Masers in C-Type Shock Waves
A. V. Nesterenok
The collisional pumping of HO and CHOH masers in magnetohydrodynamic nondissociative C-type shocks is considered. A grid of C-type shock models with speeds in the range $5-…
Probing the electron-to-proton mass ratio gradient in the Milky Way with class I methanol masers
S. A. Levshakov, I. I. Agafonova, C. Henkel +4
We estimate limits on non-universal coupling of hypothetical hidden fields to standard matter by evaluating the fractional changes in the electron-to-proton mass ratio, mu = m_e/m_…
Kinetic temperature of massive star-forming molecular clumps measured with formaldehyde IV. The ALMA view of N113 and N159W in the LMC
X. D. Tang, C. Henkel, K. M. Menten +25
We mapped the kinetic temperature structure of two massive star-forming regions, N113 and N159W, in the Large Magellanic Cloud (LMC). We have used 1\hbox{$\,.\!\!^{\prime\pri…
Influence of radiative pumping on the HD rotational level populations in diffuse molecular clouds of the interstellar medium
V. V. Klimenko, A. V. Ivanchik
We present a theoretical calculation of the influence of ultraviolet radiative pumping on the excitation of the rotational levels of the ground vibrational state for HD molecules u…
Nature of the DLA towards Q0528-250: High pressure and strong UV field revealed by excitation of CI, H2 and SiII
S. A. Balashev, C. Ledoux, P. Noterdaeme +3
We present the detection of excited fine-structure energy levels of singly-ionized silicon and neutral carbon associated with the proximate damped Lyman- system at $z_{\rm abs}=…
