Jodrell Bank Spectral Line Group
Welcome to the Jodrell Bank Spectral Line Group web page. We use radio lines to study the interstellar medium, circumstellar matter and the structure and dynamics of galaxies.
Jim Cohen 1948-2006. The order of service for Jim's memorial can be found here: Tribute to Jim and the obituary, published in the Telegraph, can be found here. We are storing as much material as possible relating to Jim's ongoing research collaborations, if you need more information you should contact Anita Richards (a.m.s.richards-at-manchester.ac.uk). Enquiries about other contacts such as with Jim's family should go to Tony Battilana (jab-at-jb.man.ac.uk).
Cosmic masers are very bright radio sources of great astrophysical significance. They can help us to understand the physical and chemical processes in regions of massive star formation and in the vicinity of post-AGB stars. We study masers at a range of frequencies using MERLIN and VLBI.
- Circumstellar Water Masers
- Mass-Loss from Red Giants
- Protostellar Disks
- Maser astrometry
- Active Galaxies
- Magnetic fields in Maser regions
- Star Formation in the Universe
- Circumstellar SiO Masers
Neutral Hydrogen (HI) is found in most galaxies, and is the main building block for star formation. We study HI in both emission and absorption.
- HI in Active Galaxies
- HI Absorption
- Multibeam HI Surveys
- Low Surface Brightness Galaxies
- High Velocity Clouds
