Sub-kiloparsec Test of the Kennicutt-Schmidt Relation in a Strongly Lensed Dusty Star-Forming Galaxy at z~2.78

C. Cornil-Baïotto, J. Molina, G. Mahler +9

[abridged] Star formation is a key process driving galaxy evolution, but understanding how it proceeds within the interstellar medium (ISM) requires resolving cold molecular gas an…

A Systematic Assessment of Total Stellar Mass Measurements with Spatially Resolved Photometry and Medium Bands at 1 < z < 9: The Impact of Mass-to-Light Variations and Outshining

Naadiyah Jagga, Adam Muzzin, Visal Sok +17

JWST NIRCam spatially resolved photometry enables studies of galaxies' stellar populations and stellar masses on sub-kpc scales. We use JWST (CANUCS, Technicolor, JUMPS) and HST da…

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…

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…

CANUCS: UV and Ionising Properties of Dwarf Star Forming Galaxies at z = 5 to 7

Anishya Harshan, Maruša Bradač, Roberto Abraham +14

The epoch of reionisation progressed through the emission of ionising photons from galaxies to their local intergalactic medium. In this work, we characterise the dwarf star-formin…

CDM not dead yet: massive high-z Balmer break galaxies are less common than previously reported

Guillaume Desprez, Nicholas S. Martis, Yoshihisa Asada +15

Early JWST observations that targeted so-called double-break sources (attributed to Lyman and Balmer breaks at ), reported a previously unknown population of very massive, evo…
