Real-time visual astronomy using image intensifiers and data modeling

SPIE Proceedings, 2003
This paper presents the use of an image intensifier as an astronomical eyepiece for real-time observation of deep sky objects. The optical frequency spectra of observational astronomical objects are reported and compared with the spectral response curve of a Generation 3 intensified optical system.

New Curriculum Development Model for Improving Undergraduate Students’ Data Literacy and Self-Efficacy in Online Astronomy Classrooms

Astronomy Education Journal, 2022
There is a critical need for research-based active learning instructional materials for the teaching and learning of STEM in online courses. Every year, hundreds of thousands of undergraduate non-science majors enroll in general education astronomy courses to fulfill their institution’s liberal arts requirements.

Data driven model based least squares image reconstruction for radio astronomy

2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
Image reconstruction problems in radio astronomy and other fields like biomedical imaging are often ill-posed and some form of regularization is required. This imposes user specified constraints to the reconstruction process that may produce an undesirable bias to the solution.

The ALMA/EVLA project data model: steps toward a common project description for astronomy

SPIE Proceedings, 2008
The "Project Data Model" (PDM) is a model of the information that describes an astronomical observing project. In this paper we consider the PDM to cover the Proposal and Observing Preparation phases (also often called Phase 1 and Phase 2), and also the intermediate phase of reviewing and approving the project.
