The Astrophysical Journal Letters, 2023 We analyze new JWST NIRCam and NIRSpec data on the redshift 9.11 galaxy MACS1149-JD1 (hereafter JD1). Our NIRCam imaging data reveal that JD1 comprises three spatially distinct components. Our spectroscopic data indicate that JD1 appears dust free but is Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge, Claudio Grillo, Nicha Leethochawalit, Piero Rosati, Stefan Schuldt, Michele Trenti, Tommaso Treu +8 moredoaj +1 more sourceFraction of Clumpy Star-forming Galaxies at 0.5 ≤ z ≤ 3 in UVCANDELS: Dependence on Stellar Mass and Environment
The Astrophysical Journal, 2023 High-resolution imaging of galaxies in rest-frame UV has revealed the existence of giant star-forming clumps prevalent in high-redshift galaxies. Studying these substructures provides important information about their formation and evolution and informs ...Zahra Sattari, Bahram Mobasher, Nima Chartab, Daniel D. Kelson, Harry I.

Astronomische Nachrichten, Volume 344, Issue 10, December 2023., 2023 Abstract
The Seyfert 2 galaxy NGC 2273 is a prime target to explore how active nuclei can be fed. It has a star‐forming innermost nuclear ring with a radius of 0.33kpc from where material may be funneled to the supermassive black hole in its center. In this article, we discuss high‐resolution adaptive optics aided JHKs images of NGC 2273 taken with the L. Schey, J. Heidt, A. Pramskiy, D. Thompson, G. Agapito, S. Esposito, R. Gredel, D.
