Turbulence measurements from H I absorption spectra
We use the millennium Arecibo 21 cm absorption-line survey measurements to examine the issue of the non-thermal contribution to the observed Galactic H I line widths. If we assume a simple, constant pressure model for the H I in the Galaxy, we find that the non-thermal contribution to the line width, vnt scales as v nt ∝ l , for vnt larger than ∼ 0.7 km s. Here l is a derived length scale and α...
متن کاملDetermination of Reaction Kinetic Parameters from Variable Temperature Kinetic Study for Oxidative Addition Reaction on Binuclear Cyclometalated Platinum(II) Complexes
The pseudo-first order rate constants and activation parameters have been determined using two methods, constant-temperature kinetic (CTK) and variable temperature kinetic (VTK), for the oxidative addition reactions of [Pt2Me2(C^N)2(µ-dppf)], (1a, C^N = deprotonated 2-phenylpyridine (ppy); 1b, C^N = deprotonated benzo[h]quinoline (bhq)) with MeI. The results obtained from VTK method are in agre...
متن کاملDescending from on high: Lyman series cascades and spin-kinetic temperature coupling in the 21 cm line
We examine the effect of Lyman continuum photons on the 21 cm background in the highredshift universe. The brightness temperature of this transition is determined by the spin temperature Ts, which describes the relative populations of the singlet and triplet hyperfine states. Once the first luminous sources appear, Ts is set by the Wouthuysen-Field effect, in which Lyman-series photons mix the ...
متن کاملThe detectability of H I 21 - cm absorption in damped Lyman - α systems
In this paper we investigate the possible reasons why H I 21-cm absorption in damped Lyman-α systems (DLAs) has only been detected at low redshift: To date, no 21-cm absorption has yet been detected at zabs > 2.3 and at redshifts less than this, there is a mix of detections and non-detections in the DLAs searched. This has been attributed to the morphologies of the galaxies hosting the DLAs, wh...
متن کاملAssociated 21 - cm H i absorption towards the radio galaxy 3 C 452 ( J 2245 + 3941 )
We report the detection of 21-cm Hi absorption towards the core of the Fanaroff-Riley II radio galaxy 3C 452 (J2245+3941). The absorption profile is well resolved into three components; the strongest and narrowest component being coincident with the velocity corresponding to [O iii] emission lines while the other two components are blue-shifted with respect to it by ∼30 amd ∼115 km s −1. If the...
