Oznake: galaksije;spektroskopija;galaxies;spectroscopy;
We analyse James Webb Space Telescope (JWST) Near Infrared Imager and Slitless Spectrograph (NIRISS) and Near Infrared Spectrograph (NIRSpec) spectroscopic observations in the Abell 2744 galaxy cluster field. From approximately 120 candidates, we identify 12 objects with at least two prominent emiss ...

Oznake: galaxies formation;star formation;high-redshift galaxies;
We present an analysis of the galaxy merger rate in the redshift range 4.0 < z < 9.0 (i.e. about 1.5 to 0.5 Gyr after the big bang) based on visually identified galaxy mergers from morphological parameter analysis. Our data set is based on high-resolution NIRCam JWST data (a combination of F150W and ...
