Reconnection in the ISM
We discuss the role of ambipolar diffusion for simple reconnection in a partially ionized gas, following the reconnection geometry of Parker and Sweet. When the recombination time is short the mobility and reconnection of the magnetic field is substantially enhanced as matter escapes from the reconnection region via ambipolar diffusion. Our analysis shows that in the interstellar medium it is t...
متن کاملthe relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
15 صفحه اولReview of the Ism Instrument and Results
Instrument Parameters: Detailed descriptions of the ISM instrument are provided by [1,2,3,4, 5]. The ISM instrument is a scanning imaging spectrometer that covers the spectral range 0.76 to 3.16 µm. For each pixel, 128 spectral measurements are acquired simultaneously. A 2-dimensional image of the surface was obtained by rotating the entrance mirror to scan in the cross track direction for the ...
متن کاملThe ISM in Nearby Galaxies
The SKA will revolutionise the study of the principles underlying Star Formation (SF), resolving interstellar cloud complexes which are the birthplaces of stars and answering such questions as which are the sufficient and necessary conditions for SF to commence. Also, massive SF is intimately related to stellar death. The SKA will be able to study the structure of the ISM at 100 pc resolution o...
متن کاملMHD Simulations of the ISM: The Importance of the Galactic Magnetic Field on the ISM “Phases”
We have carried out 1.25 pc resolution MHD simulations of the ISM, on a Cartesian grid of 0 ≤ (x, y) ≤ 1 kpc size in the galactic plane and −10 ≤ z ≤ 10 kpc into the halo, thus being able to fully trace the time-dependent evolution of the galactic fountain. The simulations show that large scale gas streams emerge, driven by SN explosions, which are responsible for the formation and destruction ...
