Abstract:
ESO has been studying the possibility of introducing a Laser Guide Star Facility (LGSF) for the VLT to serve the adaptive optics instruments foreseen on the UT3 telescope of the Paranal Observatory: NAOS-CONICA and SINFONI. The definition of the LGSF is at the conceptual design stage, with a solid baseline solution explored in detail and two open options: the final choice for the laser, and the use of a fibre relay for the laser beam instead of a mirror system. This article gives an overview of the conceptual design the authors are currently working on.

Abstract:
The advantages of the LGSF fibre relay approach are twofold: (1) one avoids the cumbersome optomechanical relay, and (2) transfers a diffraction limited beam. The authors have domonstrated that a fibre relay module is feasible. The experimental results agree well with the theoretical model. Further work on an optimised, end-face-protected, 30-m-long single-mode fibre is in progress and the first experiments will be carried out in Garching.

Abstract:
In the June 1998 issue of The Messenger (No. 92) there was an article describing the hectic days and months before the first light for UT1. First light was a great public event and of great significance for the project and the organisation. From a technical point of view however, it was a non-event. The telescope had met all specifications for first light ahead of time and the weeks before the official announcement were more a sit tight, don’t tell and don’t break it time. Following the big event we were free again to work on the machine. For those with keen eyes looking back at the beautiful images taken for the first light, flaws could easily be found. In fact a number of messages and private comments arrived at Paranal describing in great detail what we already knew. A lot of work lay ahead of us.

Abstract:
Science Operations started at UT1 Antu on April 1, 1999. This article is a brief account of the first six months (Period 63). As the statistics below will show, operations have been fairly successful. Visitor and Service modes were intermixed during P63, in a 50/50 ratio for the available time (i.e. discounting Guaranteed time, which is by definition in Visitor mode): we had 62 nights in Visitor, and 60 in Service. To this one should add 10 Service nights for the Calibration Plans, and any time allocated but not used for technical time, target of opportunity time and director discretionary time (so that in the end, more than 85 nights were devoted to Service Mode observations and calibrations).

Abstract:
The fact that the spectra of planetary nebulae (PNs) are dominated by strong emission lines, with a very weak continuum, has two interesting consequences for extragalactic work. First, PNs in other galaxies are easily detectable: we need two images of a galaxy, one taken through a narrow-band filter transmitting a strong nebular emission (e.g. [O III] 5007) and another taken through an off-band filter which does not transmit any strong nebular line. In the on-band image the PN appears as a point source. Since the nebular continuum is so weak, the point source should be invisible in the off-band image. By blinking the two images, and provided that the off-band image is deep enough, it is easy to identify the PNs. Second, for each detected PN we can measure an accurate radial velocity, because all the flux we have detected is concentrated at the redshifted wavelength of the emission line. Thus we can take a good spectrogram in an exposure time not much longer than what we need for the imaging. Since PNs are preferentially discovered in the outskirts of galaxies, where the surface brightness is lower, this means that PNs are ideal test particles for studies of rotation and mass distribution in the halos of the corresponding galaxies. Typical examples of such studies are Hui et al. (1995) on NGC 5128, and Arnaboldi et al. (1996) on the Virgo cluster galaxy NGC 4406. Here begins an unusual chain of unexpected results.

Abstract:
High-redshift radio galaxies (HzRGs) play an important role in cosmology. They are likely to be some of the oldest and most massive galaxies at high redshifts, and can therefore constrain the epoch at which the first generation of stars were formed.

Abstract:
“The VLT is Europe’s great leap forward, heralded as a new window on the distant universe. Surely we can think of some joint projects that will turn the Americans green!” Trying to rally the troops at the annual meeting of our ECfunded “Galaxy Formation” network forced me to think about where the VLT pay-off might really come. A talk from Alan Moorwood provided some valuable ideas. The first efficient near-IR spectrograph on an 8-metre telescope could detect Ha past redshift 2 and [OII] 3727 to redshift 5. How about getting kinematics for distant galaxies like those in the Hubble Deep Fields or the infamous “Steidel” objects? This would have to clarify their relation to nearer, dearer, but (perhaps) more boring galaxies. Of course, I’d never taken an infrared spectrum of anything, but why not start now?
