HO Maser Pumping: The Effect of Quasi-Resonance Energy Transfer in Collisions between H and HO Molecules

A. V. Nesterenok, D. A. Varshalovich

The effect of quasi-resonance energy transfer in collisions between H and HO molecules in HO maser sources is investigated. New data on the state-to-state rate coeffici…

H_2^{16}O and H_2^{18}O Maser Emission from Gas-Dust Clouds

Aleksandr Nesterenok, Dmitry Varshalovich

The collisional pumping of H_2^{16}O and H_2^{18}O masers in hot dense gas-dust clouds has been simulated numerically. New data on the rate coefficients for collisional transitions…

GRIPS - Gamma-Ray Imaging, Polarimetry and Spectroscopy

J. Greiner, K. Mannheim, F. Aharonian +65

We propose to perform a continuously scanning all-sky survey from 200 keV to 80 MeV achieving a sensitivity which is better by a factor of 40 or more compared to the previous missi…

Advanced Three Level Approximation for Numerical Treatment of Cosmological Recombination

Evgeny E. Kholupenko, Alexandre V. Ivanchik, Sergey A. Balashev +1

New public numerical code for fast calculations of the cosmological recombination of primordial hydrogen-helium plasma is presented. The code is based on the three-level approximat…

Asymmetry in the Spectrum of High-Velocity H2O Maser Emission Features in Active Galactic Nuclei

A. V. Nesterenok, D. A. Varshalovich

We suggest a mechanism for the amplification of high-velocity water-vapor maser emission features from the central regions of active galactic nuclei. The model of an emitting accre…

Testing cosmological variability of the proton-to-electron mass ratio using the spectrum of PKS 0528-250

A. Y. Potekhin, A. V. Ivanchik, D. A. Varshalovich +4

Multidimensional cosmologies allow for variations of fundamental physical constants over the course of cosmological evolution, and different versions of the theories predict differ…
