Gnuastro: removing extended/diffuse outliers while coadding
Mohammad Akhlaghi, Héctor Vives Arias, Pablo Renard +2
Deep astronomical images are produced by the coadding (also called "stacking") of several individual exposures. However, individual exposures are often plagued with many artifacts…
J-PLUS: Turning Off the Bright Stars
Sepideh Eskandarlou, Mohammad Akhlaghi, Johan H. Knapen +23
Photometric surveys require precise point spread function (PSF) characterization, as it varies across filters and is crucial for accurate photometry and low surface brightness (LSB…
NASIM: Revealing the low surface brightness Universe from legacy VISTA data
Elham Saremi, Ignacio Trujillo, Mohammad Akhlaghi +5
Near-infrared imaging is a powerful technique in observational astronomy, but the bright background, primarily from the Earthś atmosphere, makes the detection of faint features par…
Gnuastro: Generating polar plots in Astronomical images
Sepideh Eskandarlou, Mohammad Akhlaghi
When a structure displays dependence on distance and azimuthal angle from a center (for example the spiral arms of galaxies or the diffraction spikes of stars), projecting the pixe…
Gnuastro: measuring radial profiles from images
Raúl Infante-Sainz, Mohammad Akhlaghi, Sepideh Eskandarlou
Radial profiles play a crucial role in the analysis and interpretation of astronomical data, facilitating the extraction of spatial information. However, highly customizable (for d…
Gnuastro: visualizing the full dynamic range in color images
Raúl Infante-Sainz, Mohammad Akhlaghi
Color plays a crucial role in the visualization, interpretation, and analysis of multi-wavelength astronomical images. However, generating color images that accurately represent th…
Gnuastro: Estimating the Zero Point Magnitude in Astronomical Imaging
Sepideh Eskandarlou, Mohammad Akhlaghi, Raúl Infante-Sainz +6
Calibration of pixel values is a fundamental step for accurate measurements in astronomical imaging. In astronomical jargon this is known as estimating zero point magnitude. Here,…
Gnuastro: simulating the exposure map of a pointing pattern
Mohammad Akhlaghi
The pointing pattern is an integral part of designing one's observation strategy for a certain scientific goal. But accounting for the particular science case or instrument artifac…
