2. Molecular hydrogen emission in the interstellar medium of the Large Magellanic
We present the detection and analysis of molecular hydrogen emission towards ten interstellar regions in the Large Magellanic Cloud. We examined low-resolution infrared spectral maps of 12 regions obtained with the Spitzer infrared spectrograph (IRS). ... The excitation diagrams of the detected H2 transitions are used to determine the warm H2 gas column density and temperature. ... We find the excitation of H2 by this process is equally efficient in both atomic- and molecular-dominated regions. ...

3. Tidal Debris or HI Cloud ?
... An apparent intergalactic HI cloud of enormous spatial extent (approx. 125 x 80 kpc /h for D = 29 Mpc/h) has been serendipitously detected between the peculiar galaxies NGC~3256 and NGC~3263 in spectral-line images of the merging galaxy system NGC~3256. It was subsequently confirmed in follow-up observations toward NGC~3263 which is an edge-on galaxy displaying an extended tidal tail in the direction away from the cloud. ... Keywords. galaxies: individual (NGC 3256) - galaxies: neutral gas . ...

12. http://star.arm.ac.uk/~ambn/abstract293.html
... Time-series of high resolution spectra have been obtained during three nights and several important events were detected. Observations contained several chromospheric lines, allowing to investigate simultaneously the response of the chromosphere at different heights. A detailed analysis of the H alpha line behaviour, in particular, has revealed prominece clouds and plage-like regions in this star. ... Promience clouds are seen to lie below the co-rotation radius. ...

Observing with ESO Telescopes . ... ESO-MIDAS . ... ESO Data . ... The pipeline by default interpolates across the bad columns in the REDL CCD when it creates the master bias, but does not so when it processes the science data. This inconsistency can create boxy emission-like features as seen in the figure below. ...

16. Automatic Detection of Linear Features in Astronomical Images
... A new IRAF task has been developed that automatically identifies linear (line-like) features in an image or set of images. ... In order to automatically detect linear features, the first step is to select pixels in the image (Fig. 1 , left panel) that fall within a given data value range. ... Another aspect of extended linear features is that the image space pixels that describe them are in some way adjacent to one another and have a minimum and maximum length. ...

17. X-ray binaries with relativistic jets -- microquasars
... The jets can also be produced in smaller scale by binary stellar systems. ... Some 200 -- 250 X-ray binaries, systems in which a neutron star or black hole is accreting material from a companion star, are known. Approximately 20% of these sources have been detected at radio wavelengths, and in several cases high resolution radio observations have resolved this emission into jet-like structures, sometimes with components moving at relativistic velocities. ... It is variable radio source. ...
