exoALMA. XIV. Gas Surface Densities in the RX J1604.3−2130 A Disk from Pressure-broadened CO Line Wings
Published 2025-01-01“…Since pressure-broadened line wings are sensitive to the total gas volume density, we robustly constrain the radial dependence of the gas surface density and midplane pressure in the region located 50–110 au from the central star, which encompasses the dust ring of the system. The peak radius of the midplane pressure profile matches the dust ring radial location, directly proving radial dust trapping at a gas pressure maximum. …”

Powerful Nuclear Outflows and Circumgalactic Medium Shocks Driven by the Most Luminous Known Obscured Quasar in the Universe
Published 2025-01-01“…We find regions of low ionization consistent with large-scale shock excitation surrounding the central dust-obscured quasar, out to distances nearly 8 times the effective stellar radius of the quasar host galaxy. In the nuclear region, we find an ionized outflow driven by the quasar with velocities reaching 13,000 km s ^−1 , one of the fastest discovered to date, with an outflow rate of 2000 M _⊙ yr ^−1 and a kinetic luminosity of 6 × 10 ^46 erg s ^−1 , resulting in a coupling efficiency between the bolometric luminosity of the quasar and the outflow of 5%. …”

THE OPTIMIZATION OF ACCOMMODATION OF THE SPRAYNOZZLE ON THE PIPELINE OF THE RAINGUN OF CONTINIOUS FRONTAL ACTION
Published 2009-03-01“…The optimum distance between the spraynozzles on the pipeline under the various pressure meanings, the diameter of the outlet of the spraynozzle and the height of its installation were reckoned on the basis of the mathematical models and experimental data about the functions of distribution of precipitations on an angle of the watering zone and on its radiuses f ( α ) and f ( ρ). Two ways of accommodation of the spraynozzles on the pipeline are offered on condition of observation of the given watering zone on all the length of the pipeline and the work of the raingun pump at the maximal efficiency.…”
