... An analysis of series of flat­field exposures obtained in echelle mode adds support to the view that the performance of an instrument should be monitored closely and described quantitatively. ... This may result in confusion about basic instru­ mental parameters, the precision of the set­up, the amount and distribution of calibration frames which are required and finally the assumptions on which the data reduction procedure should rely. ... The value for pure random noise is indicated 1). ...

ALMA | ... In this section, we explain why we need to correct phase fluctuations and ALMA's strategy to do this. Rapid fluctuations will be corrected with water vapour radiometers (WVRs). The Cavendish Astrophysics Group was also a leading contributor to the ALMA prototype WVRs, which were put through their paces in tests at the Submillimeter Array (SMA). ... The Cavendish Astrophysics Group in partnership with the Onsala Space Observatory built two prototype WVRs for the ALMA project. ...

... Results Let me recall that the general goal of my research project was to try to prove a weaker version of Tate Conjecture for crystalline cohomology of algebraic varieties -- roughly speaking, one wanted to prove that for a smooth algebraic variety over a finite field of characteristic $p$, the pro-$p$ completion of its algebraic $K$-theory can be expressed in terms of the Frobenius action on cristalline cohomology. ... Other part of the project are less problematic. ...

... Students come to class with an understanding of how the world works. ... The teacher observes how the students are approaching a problem, the kind of questions they are asking and how they answer them, what concepts are solid and which ones are still evolving. ... In a constructivist class the activities the students do are relevant to them and the unit they are learning, i.e. they have to use the knowledge acquired as a tool to solve the larger question they are trying to answer. ...

Wales is approximately 242 kilometres from north to south. About two-thirds of the total population live in the South Wales coastal area, where the three biggest towns are located: Swansea, Cardiff and Newport. The Welsh are very proud of their language and culture. These are best preserved in the north and west of the country, for in the south and east they have been more challenged by industrialization. The west coast, mid Wales and North Wales are wild and beautiful! ...

... We address a question if globular clusters (GC) in a protogalaxy could for some time evolve chemically as isolated systems, enriching themselves with heavy elements produced in first supernova events that follow initial star formation. We determine both the critical mass of a protoglobular cluster that is needed to retain the ejecta of the very first supernova, and the critical energy (i.e., number of supernovae) that is needed to expel the residual gas from a cluster of a given mass. ...
