Observational Constraints on the Internal Velocity Field of Quasar Emission-Line Clouds
This paper addresses the question, what does the spectrum of a typical quasar reveal about the velocity structure within its broad emission line region clouds? Turbulent (i.e., nonthermal) broadening of spectral lines can be due to macroturbulence or microturbulence. Microturbulence a†ects line formation and the emitted spectrum and may be required to account for the observed smoothness of the ...
متن کاملThe Velocity Field of Quasar Broad Emission Line Gas
In this Letter, the broad emission line (BEL) profiles of superluminal quasars with apparent jet velocities, βa > 10, (ultraluminal QSOs, or ULQSOs hereafter) are studied as a diagnostic of the velocity field of the BEL emitting gas in quasars. The ULQSOs are useful because they satisfy a very strict kinematical constraint, their parsec scale jets must be propagating within 12◦ of the line of s...
متن کاملObservational constraints on mixed-phase clouds imply higher climate sensitivity.
Global climate model (GCM) estimates of the equilibrium global mean surface temperature response to a doubling of atmospheric CO2, measured by the equilibrium climate sensitivity (ECS), range from 2.0° to 4.6°C. Clouds are among the leading causes of this uncertainty. Here we show that the ECS can be up to 1.3°C higher in simulations where mixed-phase clouds consisting of ice crystals and super...
متن کاملDistance Constraints for High Velocity Clouds from Optical Emission Lines
We report results from a survey of high velocity clouds and the Magellanic Stream for faint, diffuse optical recombination emission lines. We detect Hα emission with surface brightness from 41 to 1680 mR from HVCs, and from < 40 to 1360 mR in the MS. A simple model for the photoionizing radiation emergent from the Galaxy, normalized to the HVCs A and M with known distances, predicts distances f...
متن کاملChemistry in Dense Molecular Clouds: Theory and Observational Constraints
For the most part, gas phase models of the chemistry of dense molecular clouds predict the abundances of simple species rather well. However, for larger molecules and even for small systems rich in carbon these models often fail spectacularly. We present a brief review of the basic assumptions and results of large scale modeling of the chemistry in dense molecular clouds. Particular attention w...
