Abstract:
MATISSE, a second generation Very Large Telescope Interferometer (VLTI) instrument, is a combined imager and spectrograph for interferometry in the 3–5 μm region (L- and M-bands) and the 8–13 μm window (N-band). MATISSE builds on the experience gained with the VLTI’s first generation instruments. It employs multi-axial beam combination while also providing wavelength differential visibility and phase, and closure-phase aperture-synthesis imaging at a range of spectral resolutions. MATISSE is designed for a broad range of science goals, and its potential for studies of the discs around young stars and active galactic nuclei are highlighted. The instrument concept and operating modes are described; construction is in progress towards installation at the VLTI in 2016.

Abstract:
Instrumentation at the Paranal Observatory is currently composed of 18 scientific instruments (operational, in commissioning or on standby) and nine technical instruments (test camera, fringe trackers, adaptive optics modules, laser guide star facility, tip-tilt sensor). Over the 15 years since their first implementation and operation, enough information on their typical behaviour has been gathered to define a global plan for preventive maintenance and/or general refurbishment for each instrument in order to retain their reliability and performance. Several examples of monitoring of instrument performance are presented and reasons for failure are listed. We describe the range of activities undertaken to ensure efficient and reliable Paranal instrumentation.

Abstract:
The B fields in OB stars (BOB) survey is an ESO Large Programme collecting spectropolarimetric observations for a large number of early-type stars in order to study the occurrence rate, properties, and ultimately the origin of magnetic fields in massive stars. A total of 98 objects was observed over 20 nights with FORS2 and HARPSpol to July 2014. Preliminary results indicate that the fraction of magnetic OB stars with an organised, detectable field is low. This conclusion, now independently reached by two different surveys, has profound implications for any theoretical model attempting to explain the field formation in these stars. We also discuss some important issues addressed by our observations (e.g., the lower bound of the field strength) and the discovery of some remarkable objects.

Abstract:
STEP (Small Magellanic Cloud in Time: Evolution of a Prototype interacting late-type dwarf galaxy) is a Guaranteed Time Observation survey being carried out at the VLT Survey Telescope. STEP will obtain homogeneous photometry in the g-, r-, i- and Hα-bands over an area of 74 square degrees covering the main body of the Small Magellanic Cloud (42 square degrees), the Bridge that connects it to the Large Magellanic Cloud (30 square degrees) and a small part of the Magellanic Stream (2 square degrees). Our photometry will allow us to detect and measure the magnitudes of individual stars well below the main sequence turnoff of the oldest populations. Here we describe the observing strategy, the photometric techniques, and the upcoming data products of the STEP survey. Preliminary results for the first two fields for which data acquisition is complete are also presented.

Abstract:
A brief overview of the first results from KROSS, a VLT/KMOS guaranteed time programme is presented. KROSS will spatially resolve the dynamics, metallicity and star formation of 1000 mass- and colour-selected galaxies at z ~ 1. These data will chart the formation of disc galaxies at the epoch of peak star formation density in the Universe.

ALESS: An ALMA Survey of Submillimetre Galaxies in the Extended Chandra Deep Field South

Abstract:
The ALESS survey is an ALMA Cycle 0 study of ~ 100 luminous high-redshift ultraluminous infrared galaxies in the Extended Chandra Deep Field South (ECDFS), one of the best-studied cosmological deep fields accessible from the southern hemisphere. These galaxies were originally selected based on their bright emission in the submillimetre continuum (so-called submillimetre galaxies, or SMGs) through observations using the APEX bolometer camera LABOCA. Compared to the single-dish LABOCA data, the interferometric ALMA data provide a positional accuracy that is nearly two orders of magnitude higher. The ALMA data thus enable galaxy identifications that were previously impossible, and so remove many of the biases inherent in previous studies of SMGs to give us our first unbiased view of a large sample of this important galaxy population.

Abstract:
GDS_1408, a relatively bright (F125W ~ 26 mag), solid z ~ 7 galaxy candidate in the Hubble Ultra Deep Field, has been the target of 52 hours of spectroscopic observations with FORS2 at the VLT. This is the deepest spectrum ever obtained for a galaxy at the epoch of reionisation. Neither emission lines nor a continuum were detected up to 10 100 Å, to a limiting equivalent width of 9 Å; a redshift of 6.82 ± 0.1 is determined, combining the superb HST photometry and the deep FORS2 spectrum. This increased redshift accuracy makes ALMA an interesting option for the confirmation of the redshift. The non-detection of Lyman-α in even the best z ~ 7 candidate demonstrates the limitations of the current generation of 8–10-metre-class telescopes for these spectroscopic confirmations; future facilities such as JWST and the E-ELT will be necessary to make decisive progress.

Abstract:
The workshop highlighted the many recent advances within the field of Herbig Ae/Be stars and the close links to star and planet formation. Topics such as magnetospheric accretion and the evolution of dust in discs, the structure of circumstellar discs and the role of walls and gaps and their links to planet formation from many observational aspects were covered. The workshop was dedicated to the life and works of George H. Herbig, who sadly passed away at the end of last year.
