The formation process for stars with masses several times that of the Sun is still unclear. The two main theories are mergers of several low-mass young stellar objects, which requires a high stellar density, or mass accretion from circumstellar disks in the same way as low-mass stars are formed, accompanied by outflows during the process of gravitational(More)
The UKIDSS Large Area Survey (LAS) began in 2005, with the start of the UKIDSS program as a 7 year effort to survey roughly 4000 square degrees at high galactic latitudes in Y, J, H and K bands. The survey also included a significant quantity of 2-epoch J band observations, with epoch baselines ranging from 2 to 7 years. We present a proper motion catalogue(More)
The AlgorithmA project has been in existence since 1991 and is used as an on-going project in the software engineering class taught at CSUSB. In 1998, the project was first implemented on the Internet using Java. In 2007, the maintenance of the project was a big challenge because of the size of the project and the complexity of the architectural design.(More)

We present an initial matching of the source positions of the Chandra Nuclear Bulge X-ray sources to the new UKIDSS-GPS near-infrared survey of the Nuclear Bulge. This task is made difficult by the extremely crowded nature of the region, despite this, we find candidate counterparts to ∼ 50% of the X-ray sources. We show that detection in the J-band for a(More)
