Hidden in Pixels I: Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales
Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56
``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…
Through Thick and Thin: The Cosmic Evolution of Disk Scale Height
Si-Yue Yu, Luis C. Ho, Takafumi Tsukui +16
To investigate the formation and evolution of vertical structures in disk galaxies, we measure global scale heights, averaging thin and thick components whe…
The ALPINE-CRISTAL-JWST Survey: Stellar and nebular dust attenuation of main-sequence galaxies at z~4-6
Akiyoshi Tsujita, Seiji Fujimoto, Andreas Faisst +39
Characterizing dust attenuation is crucial for revealing the intrinsic physical properties of galaxies. We present an analysis of dust attenuation in 18 spectroscopically confirmed…
Discovery of a Little Red Dot candidate at in COSMOS-Web based on MIRI-NIRCam selection
Takumi S. Tanaka, Hollis B. Akins, Yuichi Harikane +64
JWST has revealed a new high-redshift population called little red dots (LRDs). Since LRDs may be in the early phase of black hole growth, identifying them in the early universe is…
The ALPINE-CRISTAL-JWST Survey: Revealing Less Massive Black Holes in High-Redshift Galaxies
Wenke Ren, John D. Silverman, Andreas L. Faisst +25
We present a systematic search for broad-line active galactic nuclei (AGNs) in the ALPINE-CRISTAL-JWST sample of 18 star-forming galaxies () at redshift…
Under the glare of a luminous quasar, the FIR continuum is still an excellent tracer of the ISM down to the central kiloparsec
John D. Silverman, Emanuele Daddi, Qing-Hua Tan +7
Contamination-free assessments of the interstellar medium and star formation in quasar host galaxies, particularly based on the far-infrared, offer insights into the role of superm…
