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…

The ALPINE-CRISTAL-JWST Survey: The Fast Metal Enrichment of Massive Galaxies at z~5

Andreas L. Faisst, Lun-Jun Liu, Yohan Dubois +54

We present the stellar mass-metallicity relation (MZR) and mass-metallicity-star formation relation ("fundamental metallicity relation"; FMR) of 18 massive (log(M/Msun) = 9.5 - 11)…

Merger-driven buildup of the - relation bridging high- overmassive black holes with the local relation

Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +3

The origin of the mass scaling relation between supermassive black holes (SMBHs, ) and galaxies () remains a key open question. Rather than invoking AGN feedback,…

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…

The ALPINE-CRISTAL-JWST Survey: Chemical Abundance Comparison Between the ISM and CGM of Main-Sequence Galaxies at z=4-6

Wuji Wang, Andreas L. Faisst, Kyle Finner +37

Gaseous halos around galaxies play an important role in galaxy evolution. The exchange of metals from the interstellar medium (ISM) to the circumgalactic medium (CGM) are caused by…

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…
