Molecular Gas Disk Structures around Agns
We present new high resolution numerical simulations of the interstellar medium (ISM) in a central R ≤ 32 parsecs region around a supermassive black hole (1.3 × 10M⊙) at a galactic center. Threedimensional hydrodynamic modeling of the ISM (Wada & Norman 2002) with the nuclear starburst now includes tracking of the formation of molecular hydrogen (H2 ) out of the neutral hydrogen phase as a func...
متن کاملSmall-scale heat detection using catalytic microengines irradiated by laser.
We demonstrate a novel approach to modulating the motion speed of catalytic microtubular engines via laser irradiation/heating with regard to small-scale heat detection. Laser irradiation on the engines leads to a thermal heating effect and thus enhances the engine speed. During a laser on/off period, the motion behaviour of a microengine can be repeatable and reversible, demonstrating a regula...
متن کاملDiode laser absorption sensors for gas-dynamic and combustion flows.
Recent advances in room-temperature, near-IR and visible diode laser sources for tele-communication, high-speed computer networks, and optical data storage applications are enabling a new generation of gas-dynamic and combustion-flow sensors based on laser absorption spectroscopy. In addition to conventional species concentration and density measurements, spectroscopic techniques for temperatu...
متن کاملLaser Optothermal Detection of Absorption in Gas Flows
A new method of detection of weak absorption in gas flows is considered. It is based on probing the flow by transverse laser radiation with subsequent measurement of local temperature variations with a thermal transducer placed across the flow. The advantage of this method is a high spatial resolution (up to 0.1 mm) at sufficienly high threshold sensitivity ( ~ 10""' cm). The results of tentati...
متن کاملMolecular emission from the diffuse gas around ζ Ophiuchi
Wehavemappedλ18cmOH andλ9cmCH emission from the diffuse gas around ζ Oph, and find no trace of emission from the +4.5 km s−1 gas whose OH line was previously believed to represent pre-shock gas. The pattern of OH emission is strikingly dissimilar to those of CO, HCO+ and CH in that the strong +1 km s−1 component seen to the South is largely absent in OH. CH more closely resembles CO, peaking on...
