CHAMPS: The COSMOS High-Redshift ALMA-MIRI Population Survey - A New Census of the Dusty Early Universe
Andreas L. Faisst, Felix Martinez, Jeyhan S. Kartaltepe +86
Understanding how dust forms and evolves over cosmic time is a key open problem in extragalactic astrophysics. Galaxies in the early Universe were once thought to be mostly dust-po…
Ubiquitous nuclear disks and bars embedded in massive galaxies in the cosmic morning
Jianyuan Luo, Fangzhou Jiang, Jinning Liang +8

Galactic bars are already mature at Cosmic Noon: bar strength and flatness at z ~ 1.5
Boris S. Kalita, Luis C. Ho, John D. Silverman +6
In this work, we explore the nature of galactic bars. Once thought to be highly transient, our results demonstrate otherwise. Our sample consists of nine massive ($>10^{10.5}…
Ly-alpha emission reveals two satellite halos around massive groups at z ~ 3: the puzzling case of a quiescent central galaxy
Sicen Guo, Emanuele Daddi, Raphael Gobat +17
We present the discovery and characterisation of two Ly nebulae (LANs), RO-1001-Sat and RO-0959-Sat, as satellite structures of two giant LANs at and 3.092. They are f…
JWST MIRI/MRS observations of hot molecular gas in an AGN host galaxy at Cosmic Noon
D. Kakkad, V. Mainieri, Takumi S. Tanaka +27
Active Galactic Nuclei (AGN) are believed to play a central role in quenching star formation by removing or destroying molecular gas from host galaxies via radiation-pressure drive…
Unveiling Galaxy Structures: Systematic Analysis of Bulge+Disk Decomposition Using Simulated JWST/NIRCam Observations
Zhengxin Tang, Xuheng Ding, Boris S. Kalita +1
Characterizing and accurately decomposing galaxies into structural components, such as bulges and disks, is essential for understanding galaxy formation and evolution, particularly…
Clumpiness of galaxies revealed in the near-infrared with COSMOS-Web
Wilfried Mercier, Boris Sindhu Kalita, Marko Shuntov +30
Clumps in the rest-frame UV emission of galaxies have been observed for decades. Since the launch of the James Webb Space Telescope (JWST), a large population is detected in the re…
A PAH deficit in the starburst core of a distant spiral galaxy
Zhaoxuan Liu, John D. Silverman, Emanuele Daddi +32
We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at . The NIRCam observations mainly trace the stellar ligh…
Clumps as multiscale structures in cosmic noon galaxies
Boris S Kalita, Tomoko L Suzuki, Daichi Kashino +31
Star-forming clumps have been found to significantly influence the star formation of gas-rich galaxies. Using public data from JWST/NIRCam (COSMOS-Web) and ALMA (FMOS-COSMOS)…
A multi-wavelength investigation of spiral structures in galaxies with JWST

We investigate the deconvolved color profiles of 223 disk galaxies at redshifts of -3 observed by the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early R…
Crimson Behemoth: a Massive Clumpy Structure Hosting a Dusty AGN at
Takumi S. Tanaka, John D. Silverman, Yurina Nakazato +40
The current paradigm for the co-evolution of galaxies and their supermassive black holes postulates that dust-obscured active galactic nuclei (AGNs) represent a transitional phase…
