Aspect sensitivity of VHF echoes from field aligned irregularities in meteor trails and thin ionization layers
The aspect sensitivity of VHF echoes from field aligned irregularities (FAI) within meteor trails and thin ionization layers is studied using numerical models. Although the maximum power is obtained when a radar is pointed perpendicular to the field line (⊥B), substantial power can be obtained off the⊥B direction if the ionization trail/layer is thin. When the FAI length along B is 20 m, the po...
متن کاملThermal Ionization
In the context of an idealized model describing an atom coupled to black-body radiation at a sufficiently high positive temperature, we show that the atom will end up being ionized in the limit of large times. Mathematically, this is translated into the statement that the coupled system does not have any time-translation invariant state of positive (asymptotic) temperature, and that the expecta...
متن کاملEchoes and revival echoes in systems of anharmonically confined atoms
We study echoes and what we call “revival echoes” for a collection of atoms that are described by a single quantum wave function and are confined in a weakly anharmonic trap. The echoes and revival echoes are induced by applying two successive temporally localized potential perturbations to the confining potential, one at time t = 0, and a smaller one at time t = τ . Pulselike responses in the ...
متن کاملWhat powers Lyα blobs?⋆
Lyα blobs (LABs) are spatially extended Lyα nebulae seen at high redshift. The origin of Lyα emission in the LABs is still unclear and under debate. To study their heating mechanism(s), we present Australia Telescope Compact Array (ATCA) observations of the 20 cm radio emission and Herschel PACS and SPIRE measurements of the far-infrared (FIR) emission toward the four LABs in the protocluster J...
متن کاملT1 Maps From Shifted Echoes and Stimulated Echoes
Theory The proposed sequence is shown in Figure 1. The basic idea is to obtain a spin echo (SE) and a stimulated echo (STE) with different T1 weighting for T1 calculation. In contrast to the FastPACE technique, both echoes were acquired separately. Then, only magnitude images are required which allows for exploiting the Half Fourier technique and using phased array coils. Acquisition of the tru...
