Oznake: galaksije;gravitacijsko lečenje;rdeči premik;zvezdne kopice;nastanek zvezd;galaxies;gravitational lensing;redshift;star clusters;star formation;
We present JWST/NIRSpec integral field spectroscopy of the Cosmic Gems arc, strongly magnified by the galaxy cluster SPT-CL J0615-5746. Six-hour integration using NIRSpec prism spectroscopy (resolution ▫$R \simeq 30-300$▫ covering the spectral range ▫$0.8-5.3\ \mu$▫m, covering the spectral range ▫$0 ...

Izvirni znanstveni članek
Oznake: gravitational lensing;HII regions;high-redshift galaxies;star formation;
We present a detailed JWST/NIRSpec and NIRCam analysis of a gravitationally lensed galaxy (μ = 17 ‑ 21) at a redshift of 6.14 magnified by the Hubble Frontier Field galaxy cluster MACS J0416. The target galaxy is a typical compact and UV-faint (MUV = ‑17.8) Lyman-α emitter, yet the large magnificati ...
