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…
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,…
Costs and benefits of automation for astronomical facilities
A. Yanes-Díaz, S. Rueda-Teruel, R. Bello +57
The Observatorio Astrofísico de Javalambre (OAJ†1) in Spain is a young astronomical facility, conceived and developed from the beginning as a fully automated observatory with the m…
The Sloan Digital Sky Survey extended point spread functions
Raúl Infante-Sainz, Ignacio Trujillo, Javier Román
A robust and extended characterization of the point spread function (PSF) is crucial to extract the photometric information produced by deep imaging surveys. Here, we present the e…
