A New Window on the Hα Luminosity Function and Star Formation Rate Density from 1.2 < z < 6.6 from JWST Medium-Band Photometry
Nicholas S. Martis, Chris Willott, Gregor Rihtaršič +23
We present the first self-consistent measurement of the Hα luminosity function over a wide redshift range, covering cosmic noon into the epoch of reionization. Our analysis utilize…
Mapping dark matter in the Bullet Cluster using JWST imaging and spectroscopy
Gregor RihtarÅ¡iÄ, MaruÅ¡a BradaÄ, Guillaume Desprez +23
We present an updated gravitational lens model of the Bullet cluster (1E 0657-56) by combining JWST NIRCam imaging and NIRSpec spectroscopy. Although previous lens models relied on…
Interaction-induced star formation boosts stellar mass assembly in galaxies
Kiyoaki C. Omori, Marcin Sawicki, Rosa M. Mérida +10
Galaxy interactions are a key ingredient in galaxy evolution; not only are they a primary pathway of galaxy growth and mass assembly, but also a key driver of processes such as sta…
Resolved Ages and Stellar Metallicities in Progenitors of Milky Way Analogs: A Closer Look at their Star Formation Histories since
Vivian Yun Yan Tan, Adam Muzzin, Naadiyah Jagga +12
We present the evolution of the resolved mass-weighted age, stellar metallicity, and sSFR of 872 Milky Way Analog (MWA) progenitors up to redshift from the Canadian Unbiased…
CANUCS/Technicolor Data Release 2: A Catalogue of Galaxy Structural Parameters in up to 29 HST+JWST bands and a Multi-Wavelength Exploration of the Galaxy Size-Mass Relation at
Maya Merchant, Lamiya A. Mowla, Georgios E. Magdis +23
We present James Webb Space Telescope (JWST) results of a morphological study of galaxies in the CAnadian NIRISS Unbiased Cluster (CANUCS) and Technicolor surveys, observed in 19 m…
Between Degeneracy and Evolution: UV-to-optical Insights into the BH Model in Little Red Dots
Rosa M. Mérida, Marcin Sawicki, Chris J. Willott +2
Little Red Dots (LRDs) are a heterogeneous class of objects, with several proposed scenarios for their physical nature and evolution. While these theories have been tested on indiv…
