The BL Lac object OJ287 has been studied with the 4.2m William Herschel Telescope (WHT) from the Spanish Observatory of La Palma on six nights in December 1993 and January 1994, as part of the OJ-94 International Campaign of monitoring of OJ287. At the time of the first observations, in mid-December the object was in the decline phase of a moderate

We construct a countable inductive limit of weighted Banach spaces of holomorphic functions, which is not a topological subspace of the corresponding weighted inductive limit of spaces of continuous functions. The main step of our construction, using a special sequence of outer holomorphic functions, shows that a certain sequence space is

The critical values for the mass of the Higgs bosons, at which the theory becomes strongly interacting, are calculated using the equivalence theorem, at high energies this allows us to replace the longitudinally polarized gauge bosons in the $S$ matrix for the corresponding Goldstone bosons. An appropriate ansatz for defining the would-be Goldstone

We present visible and near infrared observations of the blazar OJ287 taken during a flare of nearly two magnitudes amplitude in V, which peaked on December 6th 1993 at V=14.5 (Kidger et al., 1993, IAUC 5909). Simultaneous visible (BVRI) and near infrared (JHK) photometry were taken on two nights during the decline phase of this outburst. The

We present the results of a combined HST/IUE/ground-based spectroscopic monitoring campaign on the Seyfert 1 galaxy NGC 5548 that was undertaken in order to address questions that require both high temporal resolution (one day) and high signal-to-noise ratios. We find (1) that the ultraviolet and optical continuum variations are virtually

Strong light bridges (SLBs) represent an abrupt change in the physical conditions of sunspot umbrae. They divide the umbra into separate units (fragments, umbral cores) and very often show a granular structure. A photometric and spectroscopic study of SLBs, and also of abnormal granulation (AG) in a region of pores, is presented. Slit-jaw images
