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…

Star Formation under a Cosmic Microscope: Highly magnified z = 11 galaxy behind the Bullet Cluster
MaruÅ¡a BradaÄ, Jon Judež, Chris Willott +20
We present measurements of stellar population properties of a newly discovered spectroscopically confirmed , gravitationally lensed galaxy, using JWST NIRS…

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…
