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…
A Post-Starburst Pathway for the Formation of Massive Galaxies and Black Holes at z>6
Masafusa Onoue, Xuheng Ding, John D. Silverman +45
Understanding the rapid formation of supermassive black holes (SMBHs) in the early universe requires insight into stellar mass growth in host galaxies. Here, we present NIRSpec res…
Near-IR clumps and their properties in high-z galaxies with JWST/NIRCam
Boris S. Kalita, John D. Silverman, Emanuele Daddi +3
Resolved stellar morphology of galaxies was inaccessible before JWST. This limitation, due to the impact of dust on rest-frame UV light, had withheld major observational conc…
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
Boris S. Kalita, Si-Yue Yu, John D. Silverman +18
Recent JWST observations have revealed the prevalence of spiral structures at . Unlike in the local Universe, the origin and the consequence of spirals at this epoch remain…
