H-Alpha Surveys and Associated Emission Line Research

The Bristol Astrophysics Group has been involved in researching galactic phenomena through emission lines for many years. Members of the group are involved in surveys of the Northern and Southern Milky Way planes.

Group members are involved in The INT/WFC Photometric H-alpha Survey of the Northern Galactic Plane (IPHAS). This is a CCD survey of the Northern Galactic plane and the main web pages for this project are at http://www.iphas.org. This survey uses the Wide Field Camera on the Isaac Newton Telescope (INT) which is part of the Isaac Newton Group (ING) of Telescopes on the island of La Palma.

The preferred mode of accessing the data is via the CASU page here. Also, Pipeline processed data from this survey is available from the Cambridge Astronomical Survey Unit (CASU) using the CASU IPHAS form or unpipelined data is availabe from Mike Irwin's IPHAS pages. The survey status and information site is maintained at Cambridge by Robert Greimel here.

In the south, the group is part of the AAO/UKST H-Alpha Survey consortium. This consortium commissioned a very high quality filter on the UK Schmidt telescope in Siding Springs, New South Wales to photographically survey the Southern Galactic Plane at the wavelength of the H-Alpha line (6563 Angstroms). There are pages for the AAO/UKST H-Alpha survey hosted at the Royal Observatory, Edinburgh here and at the Anglo Australian Observatory here. The H-alpha survey is on-line at http://www-wfau.roe.ac.uk/sss/halpha/.

Planetary Nebulae Discoveries

One of the highlights of the AAO/UKST H-Alpha has been the discovery of an unprecedented number of planetary nebulae contained in the MacQuarie/Edinburgh/Strasbourg Catalogue of Galactic Planetary Nebulae. A preliminary version of the catalogue of new planetary nebulae was published on CD in 2001 for the IAU Symposium 209 on Planetary Nebulae which was held in November 19-23, 2001, in Canberra, Australia. The reference is: The Edinburgh/AAO/Strasbourg Catalogue of Galactic Planetary Nebulae 1.0 by Parker, Q.A., Hartley, M., Russell, D., Morgan, D., Beaulieu, S., MORRIS, R.A.H., Acker, A., Ochsenbein, F., Marcout, J., Cohen, M. and PHILLIPPS, S., 2001. Published in November 2001 by Strasbourg Data Centre. The content of the CD is available on-line here

There is a page summarising the datasets available on local machines from spectroscopic followup runs here.

ChaMPlane Optical Survey: Mosaic Photometry. The ChaMPlane survey to identify and analyze the serendipitous X-ray sources in deep Galactic plane fields incorporates the ChaMPlane Optical Survey, which is one of NOAO's Long-term Survey Programs. We started this optical imaging survey in March 2000 and completed it in June 2005. Using the NOAO 4-m telescopes with the Mosaic cameras at CTIO and KPNO, deep images of the ChaMPlane fields are obtained in V, R, I and H-alpha bands. This paper describes the process of observation, data reduction and analysis of fields included in the ChaMPlane Optical Survey, and describes the search for H-alpha emission objects and Chandra optical counterparts. We illustrate these procedures using the ChaMPlane field for the black hole X-ray binary GRO J0422+32 as an example.
