Radiative pumping of 1612 MHz OH masers: OH/IR sources with IRAS LRS spectra and 34.6 micrometer absorption feature
R. Szczerba, J. H. He, P. S. Chen
The population inversion which leads to the 1612 MHz OH maser emission has long been thought to be radiatively pumped. Since OH rotational lines involved in this pumping scheme lie…

Luminosity to the Eddington luminosity ratio in AGN
B. Czerny, H. J. Witt, P. T. Zycki
We discuss the optical/UV/Xray spectra of AGN within the frame of the corona model of Witt, Czerny and Zycki (1996). In this model both the disk and the corona accrete and release…
