The FENIKS Survey has produced a detailed catalog that combines data from various telescopes and surveys. This catalog includes a wide range of information on galaxies within the UDS field. Researchers can use this catalog for various studies regarding galaxy evolution and other aspects of astronomy.

Catalog Features

The catalog presents a deep collection of Multi-wavelength data, covering 24 different filters. These filters range from optical to infrared detection. The catalog is significant for its depth, allowing scientists to observe faint and distant galaxies. It also includes information on how bright the galaxies appear, their colors, and their distances from us.

Data Sources

The catalog draws from numerous surveys and data releases, including the UKIDSS and various other significant astronomical projects. The main goal is to create a comprehensive dataset that researchers can use to advance our knowledge of the universe. This effort combines data from optical telescopes, near-infrared observatories, and space-based instruments.

Photometric Information

The catalog includes Photometric Redshifts, which help scientists determine how far away objects are. It also provides necessary data on the brightness and characteristics of galaxies. The catalog includes information on how much light the galaxies emit in different wavelengths. This information is crucial for understanding the physical properties of the galaxies.

Quality of Data

Special attention has been given to ensure the quality of the data in the catalog. The team used advanced methods to match the quality of images from different telescopes. This involves calibrating the data and ensuring that measurements taken at different times are comparable.

Stellar Population Properties

In addition to basic photometric data, the catalog also includes details on stellar population properties. This information helps researchers understand the star formation history within galaxies. It covers how stars are formed, their ages, and their distribution across different galaxies.

Importance of Multi-wavelength Observations

Using multiple wavelengths is critical to gathering a comprehensive view of celestial objects. Each wavelength reveals different information about the galaxies. For instance, optical light can highlight stars, while infrared light can penetrate dust clouds, revealing hidden structures within galaxies.

Research Applications

This catalog serves multiple research purposes. Scientists can use it to study galaxy formation and evolution, understand the distribution of dark matter, investigate star formation rates, and much more. The data aids in answering fundamental questions about the nature of the universe.

Catalog Structure

The catalog structure is designed to provide easy access to the data. Each entry includes various parameters, such as the galaxy's position, size, brightness, and redshift. Such a structured format allows researchers to quickly find and analyze the information they need.

Completeness of the Catalog

One of the strengths of this catalog is its completeness. The team has ensured that it covers a wide range of galaxy types, from near to very distant ones. This comprehensiveness allows for more reliable extrapolations when studying the universe's structure and history.

Challenges in Observing the Universe

Astronomical observations come with many challenges. Factors like atmospheric conditions, light pollution, and instrument limitations can affect the quality of the data collected. The team behind the catalog addressed these challenges through careful planning and execution, ensuring the data's reliability.

Future Prospects

The catalog is continually updated as new data becomes available. The research community is encouraged to build upon this work, asking new questions and exploring different aspects of galaxy evolution. Future observations will likely lead to even deeper insights and expand our understanding of the cosmos.

Conclusions

The FENIKS Survey and its catalog represent a significant advancement in the field of astronomy. By providing a deep, multi-wavelength dataset, it opens up new avenues for research and exploration. As scientists utilize this catalog, they will contribute to our ongoing quest to understand the universe and our place within it.

Title: The FENIKS Survey: Multi-wavelength Photometric Catalog in the UDS Field, and Catalogs of Photometric Redshifts and Stellar Population Properties

Abstract: We present the construction of a deep multi-wavelength PSF-matched photometric catalog in the UDS field following the final UKIDSS UDS DR11 release. The catalog includes photometry in 24 filters, from the MegaCam-uS (0.38 microns) band to the Spitzer-IRAC (8 microns) band, over ~ 0.9 sq. deg. and with a 5-sigma depth of 25.3 AB in the K-band detection image. The catalog, containing approximately 188,564 (136,235) galaxies at 0.2 < z < 8.0 with stellar mass > 10$^{8}$ solar masses and K-band total magnitude K < 25.2 (24.3) AB, enables a range of extragalactic studies. We also provide photometric redshifts, corresponding redshift probability distributions, and rest-frame absolute magnitudes and colors derived using the template-fitting code eazy-py. Photometric redshift errors are less than 3 to 4 percent at z < 4 across the full brightness range in K-band and stellar mass range 10$^{8}$-10$^{12}$ solar masses. Stellar population properties (e.g., stellar mass, star-formation rate, dust extinction) are derived from the modeling of the spectral energy distributions (SEDs) using the codes FAST and Dense Basis.
