Quantifying spectroscopic flux variations between JWST NIRISS and NIRSpec: slit losses in emission line measurements of z ∼ 1–3 galaxies
Nicoló Dalmasso, Maruša Bradač
Izvirni znanstveni članek
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 ...

We present a spectroscopic analysis of a broad-line active galactic nucleus (AGN) selected as a little red dot (LRD) at z = 5.3 behind the Bullet cluster (Bz5.3) based on JWST/NIRCam and NIRSpec data. The detection of strong Fe II, O I, and Ca II triplet emission lines, along with the evidence of br ...

We present the first data release of the Canadian NIRISS Unbiased Cluster Survey (CANUCS), a JWST Cycle 1 GTO program targeting five lensing clusters and flanking fields in parallel (A370, MACS0416, MACS0417, MACS1149, and MACS1423; survey area ∼100 arcmin$^2$), with NIRCam imaging, NIRISS slitless ...

We present measurements of stellar population properties of a newly discovered, spectroscopically confirmed, $z=11.10^{+0.11}_{-0.26}$, gravitationally lensed galaxy, using JWST NIRSpec PRISM spectroscopy and NIRCam imaging. The arc is highly magnified by the Bullet Cluster (magnification factor $\m ...
