Value Sliced and Derivative Images for Source Mask in JWST MIRI Photometry
Güray Hatipoğlu
One of many ways for the James-Webb Space Telescope (JWST) to capture astronomical signals is the Mid-Infrared Instrument (MIRI) Imaging mode. To make this data ready for analysis,…
JWST MIRI Imaging Data Post-Processing Preliminary Study with Fourier Transformation to uncover potentially celestial-origin signals
Güray Hatipoğlu
This manuscript reports a part of a dedicated study aiming to disentangle sources of signals from James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) imaging mode. An…
PCA-based Data Reduction and Signal Separation Techniques for James-Webb Space Telescope Data Processing
Güray Hatipoğlu
Principal Component Analysis (PCA)-based techniques can separate data into different uncorrelated components and facilitate the statistical analysis as a pre-processing step. Indep…
Utility of PCA and Other Data Transformation Techniques in Exoplanet Research
Güray Hatipoğlu
This paper focuses on the utility of various data transformation techniques, which might be under the principal component analysis (PCA) category, on exoplanet research. The first…
On the Use of Dimension Reduction or Signal Separation Methods for Nitrogen River Pollution Source Identification
Güray Hatipoğlu
Identification of the current and expected future pollution sources to rivers is crucial for sound environmental management. For this purpose numerous approaches were proposed that…
