The radial scale length of the exponential component of the disc of the Milky Way has been determined in the near infrared. We have used the TMGS (Two Micron...
The radial velocity dispersion profile of the Galactic halo: constraining the density profile of the dark halo of the Milky Way
We have compiled a new sample of 240 halo objects with accurate distance and radial velocity measurements, including globular clusters, satellite galaxies...
The radial velocity of the sun as a star and the solar cycle
Radial velocity measurements of the sun as a star using a resonant scattering spectrometer have been obtained at Izaña (Tenerife) during long observing seasons...
The Radio Galaxy Environment Reference Survey (RAGERS): a submillimetre study of the environments of massive radio-quiet galaxies at z = 1-3
Measuring the environments of massive galaxies at high redshift is crucial to understanding galaxy evolution and the conditions that gave rise to the...
The radio luminosity function from the low-frequency 3CRR, 6CE and 7CRS complete samples
We measure the radio luminosity function (RLF) of steep-spectrum radio sources using three redshift surveys of flux-limited samples selected at low (151 and...
The radio source and bipolar nebulosity in the Seyfert galaxy NGC 3516
Results of radio continuum and optical emission-line observations of the type 1 Seyfert galaxy NGC 3516 are presented. The radio maps reveal an elongated one...
The Radio Spectral Energy Distribution and Star-formation Rate Calibration in Galaxies
We study the spectral energy distribution (SED) of the radio continuum (RC) emission from the Key Insight in Nearby Galaxies Emitting in Radio (KINGFISHER)...
The rapid assembly of an elliptical galaxy of 400 billion solar masses at a redshift of 2.3
Stellar archaeology shows that massive elliptical galaxies formed rapidly about ten billion years ago with star-formation rates of above several hundred solar...
The Rapid Decay of the Optical Emission from GRB 980326 and Its Possible Implications
We report the discovery of the optical counterpart to GRB 980326. Its rapid optical decay can be characterized by a power law with exponent - 2.10+/-0.13 and a...
