... Since the pioneering work of Markarian ([ 1967 ]) objective prism surveys were recognized as a powerful tool to search for galaxies of various types of activity. ... Of special interest are blue compact galaxies (BCGs). ... A third sample of BCGs of Popescu et al. ([ 1997 ], [ 1998 ]) contains about 200 BCGs distributed in four regions of the northern sky and is based on a sample selected on the Hamburg Quasar Survey (HQS; Hagen et al. [ 1995 ]) digitised IIIa-J plates. ... 1997, 1998). ...

... Since the reddening found for the stars in Table 13 was small, no reddening correction was attempted. ... These diamonds indicate the positions of very low mass, 3 Myr old, objects from the work of Burrows et al. ... This optical V versus R - I scheme is a very powerful method of detecting very low mass (VLM) objects. ... Because of this, young brown dwarfs are intrinsically no more difficult to observe in the optical than low mass stars at the age of Orionis. ...

GALFA - H I Projects . The table below summarizes approved GALFA H I projects. Some project names link to project web sites. All scheduled project IDs link to the relevant proposal abstract in the telescope schedule database , which also lists scheduled observations for each project. If these exceed the requested observing time, a project is deemed completed ; otherwise, it is either in progress or not yet scheduled , depending on whether observations have begun. ...

Next: Leading Spaces Up: Interactive environment Previous: Interactive environment . Tab completion is enabled for all function names. If you type the first few letters of a function name, then type <TAB> the function name will be auto completed if it is un-ambiguous, or a list of possibilities will be given. Auto-completion works for the user object names as well as function names. It does not work for filenames, nor for function arguments. ...

... Initially SAI Supernova Catalogue was presented in the form of filebased system. ... The current version of SAI Supernova Catalogue presents data on supernovae together with data on their parent galaxies. ... The main source of data for the galaxies was LEDA database. ... In some cases our data were compared with the ones from the Asiago Supernova Catalogue and from List of Supernovae at Harvard-Smithsonian Center for Astrophysics, but the compilation of our Catalogue is carried out independently. ...

... Astrophysics Group . ... Pulsars . ... Stars ? ... The array was designed to detect compact radio sources such as these by virtue of the fact that they would scintillate (twinkle) when observed from the Earth through the interplanetary medium ? ... One of Antony Hewish?s research students, Jocelyn Bell, was set the task of operating the telescope and inspecting the daily charts for the kind deflections in the trace which occurred when a scintillating source passed over the array. ...

... In this activity, students will observe that the faintest stars which they can see in the sky are affected by many things: the adaptation of their eyes to the dark, the presence of clouds or haze, the time of year, and the presence of light pollution. General Information . ... After completing this activity, students should have a better understanding of the practical processes for dealing with the light pollution problem and with other environmental and societal issues. << previous page | ...
