MSA-3D: Rotation Curves and Dark Matter Fractions at z~0.5-1.7 with JWST/NIRSpec
Juan M. Espejo Salcedo, Danail Obreschkow, Karl Glazebrook +17
We present rotation curves and inner mass distributions for 30 star-forming galaxies at , observed with JWST/NIRSpec as part of the MSA-3D Cycle 1 survey. Combining spat…
The quasi-star model for Little Red Dots: potential and challenges
Fabrizio Gentile, Mauro Giavalisco, Emanuele Daddi +25
(Abridged) Little Red Dots (LRDs) are a class of sources discovered by JWST observationally defined by a "V-shaped" rest-frame UV-Optical SED, a compact or unresolved morphology, a…
Early Results from GLASS-JWST. XXVI. Spatially Resolved Star Formation and Balmer Decrements at from NIRISS Slitless Spectroscopy
Pengfei Ren, Xin Wang, Yuxuan Pang +10
Using JWST/NIRISS slitless spectroscopy, we present spatially resolved Balmer decrement measurements for 79 galaxies at , which are gravitationally lensed by the for…
Feeding the Dead: Neutral Gas Inflow in a Long-Quenched Ancient Massive Galaxy at Observed with JWST/NIRSpec
Davide Bevacqua, Danilo Marchesini, Paolo Saracco +16
We report the spectroscopic detection of neutral gas inflow into a massive () quiescent galaxy observed at with JWST. F…
BEACON: JWST NIRCam Pure-parallel Imaging Survey. II. Physical Properties of Galaxies
Yechi Zhang, Takahiro Morishita, Kimi C. Kreilgaard +23
We present photometric properties of 161 galaxy candidates at selected from the second data release (DR2) of BEACON, a JWST Cycle 2 pure-parallel NIRCam imaging program. C…
Quantifying Spectroscopic Flux Variations Between JWST NIRISS and NIRSpec: Slit Losses in Emission Line Measurements of z1-3 Galaxies
Nicolò Dalmasso, Peter J. Watson, Tommaso Treu +9
We analyze JWST NIRISS and NIRSpec spectroscopic observations in the Abell 2744 galaxy cluster field. From approximately 120 candidates, we identify 12 objects with at least a prom…
