ALMA observations of pre-JWST z ~ 10 galaxy candidates: A CO(J = 9-8) line from a ULIRG at z = 2.54 and revisit of the photometric redshifts with JWST photometry
Suzuka Arai, Yuma Sugahara, Akio K. Inoue +15
We present Atacama Large Millimetre/submillimetre Array (ALMA) observations targeting the [OIII]m line for six galaxy candidates selected with the Hubble Space Tel…
Performance of Photometric Template Fitting for Ultra-High Redshift Galaxies
Thorbjørn Clausen, Charles L. Steinhardt, Arden Shao +1
The James Webb Space Telescope (JWST) has enabled the discovery of a significant population of galaxies at z > 10. Our understanding of the astrophysical properties of these galaxi…
Direct Evidence for Stellar Initial Mass Function Variation in the Milky Way
Charles L. Steinhardt, Carter Meyerhoff, Alexander J. Luening
Because direct measurements require resolved stellar populations including low-mass stars, determining the stellar initial mass function (IMF) has been a historically difficult pro…
Direct pathway to the Early Supermassive Black Holes: A Red Super-Eddington Quasar in a Massive Starburst Host at
Qinyue Fei, Seiji Fujimoto, Gabriel Brammer +24
We present a panchromatic optical-mm characterization of GNz7q, a recently identified X-ray weak, rapidly growing red quasar embedded within a dusty starburst galaxy at ,…
Diverse reddening distributions in sight lines to type Ia supernovae
Lucas Hallgren, Radoslaw Wojtak, Jens Hjorth +1
Precise cosmological constraints from type Ia supernovae require adequately accurate corrections for host-galaxy extinction. Modelling these corrections is challenged by the proble…
Evidence for Multiple Types of Post-Starburst Galaxies
Emma W. Nielsen, Charles L. Steinhardt, Mathieux Harper +2
The quenching mechanisms of galaxies are not yet fully understood, but post-starburst galaxies provide one explanation for the rapid transition between star-forming and quiescent g…
