Abstract

The 4K$\times$4K CCD Imager is the first light instrument for the 3.6m Devasthal Optical Telescope and is producing broad-band imaging observations of many Galactic and extra-galactic sources since 2015-2016. Capabilities of the CCD Imager are demonstrated recently through several publications using the well-calibrated multi-band deep photometric results as expected from other similar facilities globally. In this article, we summarize some of the recent up-gradations made to improve the Imager, i.e., mounting the new filter wheel casing, replacing stray light baffles and discussing the fringe pattern corrections in redder filters. Some of the new science initiatives like galaxy-embedded faint point sources including WR stars and the observations of low surface brightness galaxy clusters are also discussed.

4K×4K用于360万DOT的CCD成像仪:最近的升级和结果
4K × 4K CCD成像仪是360米Devasthal光学望远镜的第一台光学仪器,自2015-2016年以来,它正在对许多银河系和星系外源进行宽带成像观测。CCD成像仪的功能最近通过一些出版物展示,这些出版物使用了校准良好的多波段深度光度测量结果,正如全球其他类似设施所期望的那样。在这篇文章中,我们总结了一些最近的升级,以改善成像仪,即安装新的滤光轮壳,更换杂散光挡板,并讨论了条纹图案校正在更红的过滤器。一些新的科学倡议,如星系嵌入的暗点源,包括WR星和低表面亮度星系团的观测也进行了讨论。

期刊介绍: The Journal of Astronomical Instrumentation (JAI) publishes papers describing instruments and components being proposed, developed, under construction and in use. JAI also publishes papers that describe facility operations, lessons learned in design, construction, and operation, algorithms and their implementations, and techniques, including calibration, that are fundamental elements of instrumentation. The journal focuses on astronomical instrumentation topics in all wavebands (Radio to Gamma-Ray) and includes the disciplines of Heliophysics, Space Weather, Lunar and Planetary Science, Exoplanet Exploration, and Astroparticle Observation (cosmic rays, cosmic neutrinos, etc.). Concepts, designs, components, algorithms, integrated systems, operations, data archiving techniques and lessons learned applicable but not limited to the following platforms are pertinent to this journal. Example topics are listed below each platform, and it is recognized that many of these topics are relevant to multiple platforms. Relevant platforms include: Ground-based observatories[...] Stratospheric aircraft[...] Balloons and suborbital rockets[...] Space-based observatories and systems[...] Landers and rovers, and other planetary-based instrument concepts[...]
