Navigation techniques for large-scale astronomical exploration

SPIE Proceedings, 2006
Navigating effectively in virtual environments at human scales is a difficult problem. However, it is even more difficult to navigate in large-scale virtual environments such as those simulating the physical Universe; the huge spatial range of astronomical simulations and the dominance of empty space make it hard for users to acquire reliable spatial ...

Structural design techniques applied in astronomical instruments

Ground-based and Airborne Telescopes VII, 2018
We present in this article some of the techniques applied at the Instituto de Astronomia of the Universidad Nacional Autonoma de Mexico (IA-UNAM) to the mechanical structural design for astronomical instruments. With this purpose we use two recent projects developed by the Instrumentation Department.

Shapelets and related techniques in radio-astronomical imaging

2011 XXXth URSI General Assembly and Scientific Symposium, 2011
We present the use of orthonormal basis functions, in particular, shapelets and prolate spheroidal wave functions, in radio astronomical imaging. By using such methods, it is possible to overcome some limitations of traditional pixel based image deconvolution.
