Early Results From GLASS-JWST. XII: The Morphology of Galaxies at the Epoch of Reionization
T. Treu, A. Calabro, M. Castellano +23
Star-forming galaxies can exhibit strong morphological differences between the rest-frame far-UV and optical, reflecting inhomogeneities in star-formation and dust attenuation. We…
Early results from GLASS-JWST. VII: evidence for lensed, gravitationally bound proto-globular clusters at z=4 in the Hubble Frontier Field A2744
E. Vanzella, M. Castellano, P. Bergamini +29
We investigate the blue and optical rest-frame sizes (lambda~2300A-4000A) of three compact star-forming regions in a galaxy at z=4 strongly lensed (x30, x45, x100) by the Hubble Fr…
The Size and Pervasiveness of Ly-UV Spatial Offsets in Star-Forming Galaxies at
B. C. Lemaux, S. Fuller, M. BradaÄ +20
We study the projected spatial offset between the ultraviolet continuum and Ly emission for 65 lensed and unlensed galaxies in the Epoch of Reionization (), the f…
Early results from GLASS-JWST. X: Rest-frame UV-optical properties of galaxies at 7 < z < 9
N. Leethochawalit, M. Trenti, P. Santini +23
We present the first James Webb Space Telescope/NIRCam-led determination of galaxy properties based on broadband imaging from 0.8 to 5~ as part of the GLASS-J…
Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr
E. Vanzella, F. Loiacono, M. Messa +38
We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…
An extremely metal poor star complex in the reionization era: Approaching Population III stars with JWST
E. Vanzella, F. Loiacono, P. Bergamini +31
We present JWST/NIRSpec integral field spectroscopy (IFS) of a lensed Population III candidate stellar complex (dubbed Lensed And Pristine 1, LAP1), with a lensing-corrected stella…
Early results from GLASS-JWST. VI: Extreme rest-optical equivalent widths detected in NIRISS Wide Field Slitless Spectroscopy
K. Boyett, S. Mascia, L. Pentericci +27
Wide Field Slitless Spectroscopy (WFSS) provides a powerful tool for detecting strong line emission in star forming galaxies (SFGs) without the need for target pre-selection. As pa…
The GLASS James Webb Space Telescope Early Release Science Program. I. Survey Design and Release Plans
T. Treu, G. Roberts-Borsani, M. Bradac +43
The GLASS James Webb Space Telescope Early Release Science (hereafter GLASS-JWST-ERS) Program will obtain and make publicly available the deepest extragalactic data of the ERS camp…
