The confusion limit on astrometry with SIM
Jayadev Rajagopal, Torsten Boeker, Ronald J. Allen
An important requirement for the Space Interferometry Mission (SIM) is to carry out precision astrometry in crowded fields. This capability is crucial, for example, to accurately m…
Molecular gas associated with the IRAS-Vela shell
Jayadev Rajagopal, G. Srinivasan
We present a survey of molecular gas in the J = 1 -> 0 transition of 12CO towards the IRAS Vela shell. The shell, previously identified from IRAS maps, is a ring-like structure see…
The interstellar clouds of Adams and Blaauw revisited: an HI absorption study - II
Jayadev Rajagopal, G. Srinivasan, K. S. Dwarakanath
In the preceding paper (paper I), we presented HI absorption spectra towards radio sources very close to the lines of sight towards 25 bright stars against which optical absorption…
The interstellar clouds of Adams and Blaauw revisited: an HI absorption study - I
Jayadev Rajagopal, G. Srinivasan, K. S. Dwarakanath
This investigation is aimed at clarifying the nature of the interstellar gas seen in absorption against bright O and B stars. Towards this end we have obtained for the first time H…
