Starburst galaxies and structure in the submillimetre background towards the Hubble Deep Field

J. A. Peacock, M. Rowan-Robinson, A. W. Blain +10

We use an 850-micron SCUBA map of the HDF to study the dust properties of optically-selected starburst galaxies at high redshift. Although the 850-micron map does not allow detecti…

X-ray variability in a deep, flux limited sample of QSOs

O. Almaini, A. Lawrence, T. Shanks +6

We present an analysis of X-ray variability in a flux limited sample of QSOs. Selected from our deep ROSAT survey, these QSOs span a wide range in redshift () and are ty…

Massive Lossless Data Compression and Multiple Parameter Estimation from Galaxy Spectra

Alan Heavens, Raul Jimenez, Ofer Lahav

We present a method for radical linear compression of datasets where the data are dependent on some number of parameters. We show that, if the noise in the data is independent…

Interstellar and Circumstellar Optical & Ultraviolet Lines Towards SN1998S

David V. Bowen, Katherine C. Roth, David M. Meyer +1

We have observed SN1998S which exploded in NGC3877, with the UES at the WHT and with the E230M echelle of STIS aboard HST. Both data sets were obtained at two seperate epochs. From…

A survey of UV-excess AGNs in the South Galactic Pole

F. La Franca, C. Lissandrini, S. Cristiani +3

Spectra, position, magnitudes and colors are presented for 485 faint (B<20.5) emission line objects selected with the ultraviolet-excess (UVX) criterion on a area of 24.6 sq. deg i…

The Surface Density of Extremely Red Objects

D. Thompson, S. V. W. Beckwith, R. Fockenbrock +10

We present initial results from a field survey for extremely red objects (EROs, defined here as (R-K') >= 6 mag) covering 154 square arcminutes of sky, from the first of 7 deep, wi…
