... Many of these radi HII regions lie beyond the range of optical detection, at distances exceeding several kpc; they thus provide a comprehensive coverage of the southern HII regions in the Galaxy over the longitude range 210 to 360^o and consistute a vital data base for the study of galactic structure. ...

If material ejected from the Earth contains microorganisms and spores, the question arises whether life may be carried from planet to planet within the solar system. ... However, the solar system is tiny on the scale of the Galaxy, and it has generally been thought that the transfer of life between stars is impossible -- the microorganisms would be destroyed by cosmic rays, ultraviolet light and so on. ...

...

HI spectral-line observations of galaxies (Karen O'Neil) . Measuring the width, flux, etc. of the HI profile of two galaxies, using some combination of : dwarf emission line, HVC emission line, spiral emission line, and spiral absorption line. This project was designed to demonstrate the fundamentals of spectral line observing and position switching. ... The types of galaxies observed in this project are being kept open and will be determined when the project LST is known. ...

... Galaxy Evolution home . ... Cosmological evolution of star-forming galaxies . ... Galaxy Evolution is one of five research themes within the Cavendish Astrophysics group in the Department of Physics, Cambridge. The two main research interests within the Galaxy Evolution area are the cosmological evolution of star forming galaxies, in particular the physical mechanisms regulating star formation, and secondly the origin and evolution of radio sources and the effect they have on their environment. ...

... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...
