DB is not privatized, it is 100% state-owned. As far as I know, all ICE power cars are still in use today, except for the one destroyed in the Eschede accident.

Spiegel Online found out that (for some reason) parts of the text are visible in the bookmarks of the PDF if it is right after a section heading. This includes the redacted text. p…

I just checked the twitter account of the first author (who does not seem to be currently affiliated with any scientific institution). I can only understand his German and English …

I have experience only with the Very Large Telescope run by ESO in Chile, maybe what I write is only valid there. There is usually no real schedule of targets for ground-based tele…

In short: No, we cannot do that at the moment. We have photometric all-sky surveys that can map the entire sky (visible from the telescope location) during a night up to a certain …

I like NGC 3201 because we found a stellar mass black hole in it ( https://www.eso.org/public/news/eso1802/ ). There should be many more of them in all clusters, but they are hard …

Not sure if you meant it like this but redshift estimation comes to my mind. The farther away a galaxy is, the redder it becomes. You can measure the distance (redshift) from galax…

Absolutely! When the lasers are used, MUSE uses a filter at the correct wavelength (Natrium D) to get rid of the laser photons. Only one telescope is currently equipped with lasers…

I was comparing it to HST WFC3 with a field of view of 160 x 160 arcsec^2 ( https://www.spacetelescope.org/about/general/instruments/wfc... ). Thats about 450 times larger than the…

This is very much unexplored territory, but ESO thinks so. The ELT ( https://www.eso.org/public/teles-instr/elt/ ) will use more lasers but the exact configuration is still work in…

Exactly! One datacube that comes out from the instrument contains 300 x 300 spectra. This is actually the main capability of the instrument which has 24 individual spectrographs. H…

Yes, the diffraction limit is meant here. The VLT has four 8 m mirrors, for each of them the angular resolution limit is = wavelength/diameter = 8 * 10^(-8) rad. The practical reso…

The advantage of MUSE is that you get all color information, i. e. the flux at any wavelength from blue to red. In principle, one can use this together with the sensitivity curve f…

We can achieve a very high resolution from the ground but only in a very small field of view. To cover one typical HST image with MUSE at the VLT, we would need a mosaic of hundred…

In this narrow-field mode of MUSE, the CCD detector can resolve 0.025 arcseconds per pixel (arcsecond is a weird unit for angles used in astronomy). At the current distance to Nept…

I'm a PhD student working with data of globular clusters from this instrument for quite some time now. I will be happy to answer your questions!

Does anyone know similar books? I. e. about the history of a company from an insider's perspective?

I was tired of going through arxiv's rss feeds so I wrote a script that sends me a mail if there is anything interesting. http://myarxiv.org/
