Physical Properties of Spectroscopically-Confirmed Galaxies at . III. Stellar Populations from SED Modeling with Secure Ly Emission and Redshifts
Linhua Jiang, Kristian Finlator, Seth H. Cohen +9
We present a study of stellar populations in a sample of spectroscopically-confirmed Lyman-break galaxies (LBGs) and Ly emitters (LAEs) at . These galaxies have deep o…
Are Ultra-faint Galaxies at z=6-8 Responsible for Cosmic Reionization ? Combined Constraints from the Hubble Frontier Fields Clusters and Parallels
Hakim Atek, Johan Richard, Mathilde Jauzac +8
We use deep Hubble Space Telescope imaging of the Frontier Fields to accurately measure the galaxy rest-frame ultraviolet luminosity function (UV LF) in the redshift range $z \sim…
Automatic Generation of Question Hints for Mathematics Problems using Large Language Models in Educational Technology
Junior Cedric Tonga, Benjamin Clement, Pierre-Yves Oudeyer
The automatic generation of hints by Large Language Models (LLMs) within Intelligent Tutoring Systems (ITSs) has shown potential to enhance student learning. However, generating pe…
[CII] emission in z ~ 6 strongly lensed, star-forming galaxies
Kirsten K. Knudsen, Johan Richard, Jean-Paul Kneib +5
The far-infrared fine-structure line [CII] at 1900.5\,GHz is known to be one of the brightest cooling lines in local galaxies, and therefore it has been suggested to be an efficien…
New Constraints on the Faint-end of the UV Luminosity Function at z~7-8 using the Gravitational Lensing of the Hubble Frontier Fields Cluster A2744
Hakim Atek, Johan Richard, Jean-Paul Kneib +8
Exploiting the power of gravitational lensing, the Hubble Frontier Fields (HFF) program aims at observing six massive galaxy clusters to explore the distant Universe far beyond the…
Probing the z>6 Universe with the first Hubble Frontier Fields cluster Abell 2744
Hakim Atek, Johan Richard, Jean-Paul Kneib +8
The Hubble Frontier Fields (HFF) program combines the capabilities of the Hubble Space Telescope (HST) with the gravitational lensing of massive galaxy clusters to probe the distan…
