We present a 5–37 μm infrared spectrum obtained with the Spitzer Space Telescope toward the southeastern lobe of the young protostellar outflow HH211. The spectrum shows an extraordinary sequence of OH emission lines arising in highly excited rotational levels up to an energy E/ k ≈ 28200K above the ground level. This is, to our knowledge, by far the highest rotational excitation of OH observed...

Effective star formation rates in tabular form are computed which yield a prescription for the star formation activity in model galaxies as a function of ambient density, metallicity, and stellar feedback. The effects of supernova explosions on the thermal balance of the Interstellar Medium (ISM) and the presence of a multi-phase ISM are explicitly included. The resulting grid of models can be ...

We investigate the propagation of a shock wave into a warm neutral medium and cold neutral medium by one-dimensional hydrodynamic calculations with detailed treatment of thermal and chemical processes. Our main result shows that thermal instability inside the shock-compressed layer produces a geometrically thin, dense layer in which a large amount of hydrogen molecules is formed. Linear stabili...

ISM is a well-proven strategy for analyzing the synergic influences of various attributes to the overall system under study. The unique feature of ISM is that it analyzes the attributes based on their driving power and dependence. In the current study, the ISM has been developed for a leading telecom service provider operating in various global regions having their head quarters in India. The h...

Intraday Variability of compact extragalactic radio sources can be interpreted as quenched scintillation due to turbulent density fluctuations of the nearby ionized interstellar medium. We demonstrate that the statistical analysis of IDV time series contains both information about sub-structure of the source on the scale of several 10 μas and about the turbulent state of the ISM. The source str...

In recent years, image-scanning microscopy (ISM, also termed pixel-reassignment microscopy) has emerged as a technique that improves the resolution and signal-to-noise compared to confocal widefield by employing detector array at image plane of laser scanning microscope. Here, we present k-space analysis coherent ISM, showing ISM is equivalent spotlight synthetic-aperture radar (SAR) analogous ...
