An Optical-UV Survey of the North Celestial Cap

TL;DR

This paper reports on an early optical-UV survey of the North Celestial Cap, providing valuable photometric and astrometric data for a poorly studied region at high galactic latitudes, with implications for galactic structure and galaxy clustering.

Contribution

It introduces the NCCS, a new survey covering 5% of the area, offering the first detailed optical-UV data for the North Celestial Cap region.

Findings

Approximately 1.5 million objects detected.

Insights into galactic structure and extinction.

Analysis of galaxy clustering in color-color diagrams.

Abstract

We present preliminary results of an optical-UV survey of the North Celestial Cap (NCCS) based on ~5% areal coverage. The NCCS will provide good photometric and astrometric data for the North Celestial Cap region (80 < DEC < 90). This region, at galactic latitudes 17 < b < 37, is poorly covered by modern CCD-based surveys. The expected number of detected objects in NCCS is ~1,500,000. We discuss issues of galactic structure, extinction, and the galaxy clustering in the colour-colour diagrams.
