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…

UV slopes of Starforming Galaxies in Strong Lensing fields at the Epoch of Reionization with JWST

Giordano Felicioni, Maruša Bradač, Yoshihisa Asada +20

UV slopes () are a powerful diagnostics for galaxies at the Epoch of Reionization, tracing star formation, ISM ionization, and the escape fraction of ionizing photons…

Earliest Galaxy Evolution in the CANUCS+Technicolor fields: Galaxy Properties at seen with the Full NIRCam Medium and Broad Band Filters

Yoshihisa Asada, Chris Willott, Adam Muzzin +18

We present a sample of galaxies by exploiting one of the richest JWST NIRCam imaging data, taken in the CANUCS survey in Cycle 1 and the Technicolor (TEC) s…

Star Formation under a Cosmic Microscope: Highly magnified z = 11 galaxy behind the Bullet Cluster

Maruša Bradač, Jon Judež, Chris Willott +20

We present measurements of stellar population properties of a newly discovered spectroscopically confirmed , gravitationally lensed galaxy, using JWST NIRS…

A deep dive down the broad-line region: permitted OI, CaII and FeII emission in an AGN Little Red Dot at z=5.3

Roberta Tripodi, Maruša Bradač, Francesco D'Eugenio +27

We present a spectroscopic analysis of a broad-line active galactic nucleus (AGN) selected as little red dot at behind the Bullet cluster (Bz5.3), based on JWST/NIRCam an…

In Search of the First Stars: An Ultra-Compact and Very Low Metallicity Lyman- Emitter Deep Within the Epoch of Reionization

Chris J. Willott, Yoshihisa Asada, Kartheik G. Iyer +16

We present {\it JWST} observations of a gravitationally-lensed, extremely metal-poor galaxy at redshift from the CANUCS survey. Based on the low oxygen to Balmer…
