A JWST View of Cosmic Star Formation from to 9 with Hydrogen Recombination Lines in the COSMOS and GOODS-N fields
Shuqi Fu, Linhua Jiang, Christopher J. Conselice +9
We combine wide-area COSMOS-3D observations with deeper GOODS-N data from JWST/NIRCam F444W wide-field slitless spectroscopy to trace cosmic star formation over --9. The ob…
COSMOS-3D: Spectro-photometric Confirmation of Shabgard, a Cool, Metal-poor Brown Dwarf in the COSMOS Field
Bahareh S. Salmasi, Priyanka Jalan, Tomotsugu Goto +19
Brown dwarfs are unique laboratories for studying cool atmospheres, the low-mass end of star formation, and the transition between stars and giant planets. Identifying and characte…
Tracing Obscured AGN Contribution and Number Fraction Across 0 < z < 6 with JWST
Angel Rodriguez Barbosa, Tomotsugu Goto, Daryl Joe D. Santos +8
Active galactic nuclei (AGN) are key drivers of galaxy evolution, yet many remain undetected in ultraviolet and optical surveys due to heavy dust obscuration. In these systems, abs…
The MAGPI Survey: Evidence for Non-Universal Resolved Dust Attenuation Relations Beyond the Local Universe
A. Mailvaganam, T. Zafar, P. Corcho-Caballero +39
We study the spatially resolved relation between dust attenuation () and star formation rate surface density () in galaxies from the MAGPI survey ($0.25 < z…
Stacked Hybrid RNN-CNN Reconstruction of X-ray Influence on 21-cm Brightness Temperature
S. Mobina Hosseini, Bahareh Soleimanpour Salmasi
The X-ray photons substantially affect the thermal and ionization states of the intergalactic medium (IGM) during the Epoch of Reionization (EoR), thereby significantly influencing…
A New Constraint on the Simulation of the Intergalactic Medium through the Evolution of the Neutral Hydrogen Fraction in the Epoch of Reionization
S. Mobina Hosseini, Bahareh Soleimanpour Salmasi, Seyed Sajad Tabasi +1
The thermal history of the intergalactic medium is full of extremely useful data in the field of astrophysics and cosmology. In other words, by examining this environment in differ…
