Balmer Break Measurements Trace Departures from the Star-Forming Main Sequence at with JWST/NIRSpec
Suprabhas Narisetty, Yongda Zhu, Eiichi Egami +4
We present JWST/NIRSpec PRISM observations of galaxies at to study the relation between Balmer-break strength () and recent star formation. Using NIRSpec sp…
SN Helios: A Multiply Imaged Type II Supernova Opening Time-Delay Cosmography beyond redshift of 3
Seiji Fujimoto, Conor Larison, Justin D. R. Pierel +64
We report the discovery and spectroscopic confirmation of SN Helios, a strongly lensed, multiply imaged Type II supernova (SN) at behind the galaxy cluster RXC J0018.5+162…
LATED: JWST integral field spectroscopy of a galaxy caught in chemical infancy at behind Abell 2744
Mingyu Li, Roberto Maiolino, Zheng Cai +26
When Population III (Pop III) star formation ended remains an open question. LATED-1 is an intrinsically faint () Ly emitter at revealed by VLT/MU…
LATED: Ly-anchored photometric selection of candidate metal-free and extremely metal-poor star formation from the end of reionisation to cosmic noon
Mingyu Li, Zheng Cai, Roberto Maiolino +24
Cosmological simulations allow a low-level tail of Population III (Pop III) star formation to persist to . Spectroscopic confirmation is expensive, so an efficient photometr…
An Archival Calibration of JWST/MIRI Prism Wide-Field Slitless Spectroscopy: Methodology, Performance, and a Mid-Infrared Spectral Atlas of Galaxies at in the GOODS-N/S Fields
Fengwu Sun, Javier Álvarez-Márquez, Eiichi Egami +4
Through the Low Resolution Spectroscopy (LRS) observing mode of JWST/MIRI, the P750L prism disperses the entire ~70"110" imager field, turning MIRI into a wide-field slitle…
The Roman eXtreme Deep Field (RXDF)
Haojing Yan, Anton M. Koekemoer, Yue Shen +127
The Roman eXtreme Deep Field (RXDF) program is one of the five General Astrophysics Survey (GAS) programs approved for observing time with the Nancy Grace Roman Space Telescope in…
