Self-Stark Limit on Brightness Temperature in Cosmic Masers
نویسنده
چکیده
The radiation broadening of narrow maser lines by its own emission which can also be described as resonance Self-Stark effect puts an upper limit on the brightness temperature of cosmic masers. It is shown that available measurements of the brightness temperature of OH and water masers are consistent with the observed narrow line widths only if the maser emission is highly directive.

Space - VLBI observations of OH masers
We report on the first space-VLBI observations of the OH masers in two main-line OH transitions at 1665 and 1667 MHz. The observations involved the space radio telescope on board the Japanese satellite HALCA and an array of ground radio telescopes. The maps of the maser region and images of individual maser spots were produced with an angular resolution of 1 mas, which is several times higher t...
متن کاملAccounting for Cosmic Variance in Studies of Gravitationally-lensed High-redshift Galaxies in the Hubble Frontier Field Clusters
Strong gravitational lensing provides a powerful means for studying faint galaxies in the distant universe. By magnifying the apparent brightness of background sources, massive clusters enable the detection of galaxies fainter than the usual sensitivity limit for blank fields. However, this gain in effective sensitivity comes at the cost of a reduced survey volume and, in this Letter, we demons...

Introduction: Diagnosis of primary and secondary cancers to treat patients with diffuse and malignant tumors is an important subject. The appropriate treatment will be eliminating primary and metastatic tumors. Radiofrequency ablation with localized heat induction in the target tissue causes irreversible cellular damage and tissue coagulation. Estimation of tissue temperature c...
متن کاملH 2 O Masers and Supersonic Turbulence
Received ; accepted – 2 – ABSTRACT We use unpublished and published VLBI results to investigate the geometry and the statistical properties of the velocity field traced by H 2 O masers in five galactic regions of star formation — Sgr B2(M), W49N, W51(MAIN), W51N, and W3(OH). In all sources the angular distribution of the H 2 O hot spots demonstrates approximate self-similarity (fractality) over...
