Gas Fraction and Depletion Time Drive the Main-Sequence Scatter in Massive Galaxies at
Daichi Kashino, Boris S. Kalita, John D. Silverman +8
We present ALMA Band 7 dust continuum observations of 57 massive () star-forming galaxies at , selected from the FMOS-COSMOS survey t…
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…
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…
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…
