Dust, Stars and Nuclear Activity in the Centres of SBC Galaxies
Emission from the central few Kpc of a normal Sbc spiral comes from a population of older bulge stars and one of younger disc stars, both modified by dust extinction. In some apparently normal galaxies a compa...

New Results on CMB Structure From the Tenerife Experiments
Temperature fluctuations in the CMB (Cosmic Microwave Background) are a key prediction of cosmological models of structure formation in the early Universe. Observations at the Teide Observatory, Tenerife using...

Results with the Extended Merlin
A major enhancement of MERLIN completed in 1992 has led to a transformation of its capabilities. The seventh telescope added to the array is a 32-m telescope at Cambridge which provides high sensitivity on all...

The Magnetic Field in the Local Spiral Arms
Optical and radio observations provide an extensive body of data on the morphology and intensity of magnetic fields in our Galaxy. Zeeman effect measurements in interstellar gas clouds show that the magnetic f...

Direct observation of structure in the cosmic microwave background
Temperature fluctuations in the cosmic microwave background are a key prediction of cosmological models of structure formation in the early Universe. Ground-based multi-frequency radio observations of the micr...

Anisotropy measurements of the cosmic microwave background radiation at intermediate angular scales
Galaxy formation by gravitational instability implies the presence of temperature fluctuations in the cosmic microwave background. New observations at 10.45 and 14.9 GHz from the Observatorio del Teide in Tene...

Observations of Microwave Background Anisotropy at Tenerife and Cambridge
A brief summary of the status of microwave background anisotropy observations at Tenerife and Cambridge is given. New 15 GHz Tenerife results give a preliminary limit of ΔT/T ≲ 2.5 x 10-5 on an angu...

Radio and Optical Observations of the Nuclei of Sbc Galaxies
A sample of 100 Sbc galaxies is being observed at different wavelengths and with high resolution, in order to obtain information about the physical process happening in their nuclei. We present here the compar...

Multifrequency study of the nuclei of Sbc galaxies
A sample of 100 Sbc galaxies has been observed at different wavelengths and resolutions. The ultimate aim of the project is to probe the origin of their nuclear activity, e.g., blackhole, starbust, etc.

Peculiar Velocities of Nearby Spiral Galaxies
We report measurements of peculiar velocities from a sample of over 300 intermediate-type spiral galaxies. The galaxies have been observed at λ21cm at Jodrell Bank and Parkes (Staveley-Smith & Davies 1987,1988...

Large Scale Structure: Its possible imprint on the CMB?
We present the new results of the Jodrell-IAC Cosmic Microwave Background (CMB) anisotropy experiment for declination +40°. A similar level of sensitivity has been achieved with respect to the reported previou...

Spiral Galaxies as Indicators of the Hubble Flow
We have chosen a sample of 307 Sb-Sc galaxies for an accurate study of the motions of local galaxies relative to the uniform Hubble flow. This work extends that of Hart and Davies (1982) who studied a sample o...

Radio Observations of NGC1275 at 90 and 20cm
We present high dynamic range VLA maps of NGC1275 at 20cm and 90cm , with resolutions ranging from 1″ to 40″. Over the central 30″ there is evidence for collimated ejection in PA 160 degrees. Outside this the ...

Sensitive measurement of fluctuations in the cosmic microwave background
Extensive high sensitivity observations of the cosmic microwave background have been made on an angular scale of 8° covering a substantial fraction of the northern sky. An observed anisotropy in the sky emiss...

High Sensitivity Observations of the Microwave Background Radiation
Angular fluctuations in the cosmic microwave background radiation are indicators of the seed structure at recombination (z ≃ 1000) which subsequently evolves into the present-day Universe (z = 0). Such measure...

The Spatial and Peculiar Velocity Distribution of Galaxies within 80 MPC
Strong evidence for the existence of elongated or filamentary structure in the nearby Universe comes from 2-dimensional galaxy distributions supplemented by redshift information (e.g. Davis et al. 1982). The 2...

Microwave Decrement Measurements in Galaxy Clusters
Photons from the 3K cosmic microwave background originating at z ~ 1500 are inverse Compton scattered on passing through the hot (107 to 108K) gas in galaxy clusters. Photons from the Rayleigh-Jeans (λ ≫ 1mm) par...
