1. http://www.stsci.edu/jwst/doc-archive/flyers/JWST-Proto-Planet.pdf
... The spectroscopic modes of JWST NIRSpec and MIRI cover the main molecular bands of gas in planet-forming regions, tracing gas at temperatures of 100-1000 K. The integral field units of JWST will resolve the molecular emission in nearby protoplanetary disks, while the high sensitivity will allow observations of disks as far away as the Magellanic Clouds, constraining the chemistry of planet formation in a wide range of environments. ...

3. Research - Compact high-velocity clouds around the Milky Way
... High-velocity clouds (HVCs) were discovered by Muller, Oort & Raimond (1963) in the 21-cm line emission of neutral, atomic hydrogen. They are gas clouds which are characterised by high radial velocities incompatible with a participation in the rotation of our Galaxy. ... This suggestion was seized by Braun & Burton (1999) who identified 66 compact high-velocity clouds (CHVCs) with positional and kinematic characteristics being compatible with a distribution across the entire Local Group. ...

The compression of the cloud of gas in star forming . ... These data have allowed us to create the dynamic model of the cloud of gas, around this object. ... The results on H2CO absorption lines (figure 1) have shown, that the central part of the cloud represents a clumped envelope of diameter 9 pc with radial velocity 20 km/s. The relation of radial velosity of absorption line and the whole object have allowed simple to define the direction of radial movement - itis compression. ...

... The presence of solidstate emission bands is compared to other indicators of circumstellar material, such as Hff emission, optical variability and submm continuum fluxes. ... However, a strong dependence on spectral type of the central star seems to be present: stars with spectral type earlier than B9 show either amorphous silicate in absorption or infrared spectra dominated by PAH emission, whereas more than 70% of the stars of later spectral type show silicate emission. ...

17. Pink Black Holes: Frequently Asked Questions
... We have measured this "redshift" for the pink black holes, and allowed for it in our calculations. ... We see this effect in the emission from gas around these pink black holes, but it is far too small an effect to account for the pinkness. Thus the swirling motions of gas around or into the black holes cannot produc the colour. ... At first we thought that these things were normal blue black holes hidden behind clouds of interstellar dust, that absorbed the blue light and made them appear pink. ...
