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…
Cosmic Noon Galaxies in the Hubble Ultra Deep Field with MIRI Wide-Field Slitless Spectroscopy
S. Kendrew, G. Östlin, L. Colina +29
We present results from a survey of the Hubble Ultra-Deep Field using the Wide-Field Slitless Spectroscopic (WFSS) capability of the Mid-Infrared Instrument (MIRI) on JWST, demonst…
PRISMS. GHZ1. A standard tale of galaxy evolution with atypical ionizing conditions at
Borja Pérez-Díaz, Marco Castellano, Javier Álvarez-Márquez +33
[Abridged] The first operating years of the James Webb Space Telescope (JWST) have revealed a surprising number of UV-bright objects, many of them characterized by t…
RIOJA. Environmental Effects on Stellar Populations and Ionized Gas in a Protocluster at
Wataru Osone, Takuya Hashimoto, Javier Álvarez-Márquez +23
Protoclusters in the epoch of reionization provide key laboratories for investigating how environment shapes early galaxy formation and evolution, and may also have contributed to…
Deep Spectroscopic Follow-Up of Maisie's Galaxy -- A Typical Galaxy in the Early Universe
Rebecca L. Larson, Taylor A. Hutchison, Steven L. Finkelstein +26
The first several years of JWST observations have yielded surprisingly large numbers of bright galaxies, with follow-up spectroscopy of many of these sources implying extrem…
Stratification of the AGN-Driven multi-phase outflows in the dwarf Seyfert galaxy NGC 4395
Payel Nandi, Luis Colina, Rogemar A. Riffel +5
We present a multi-wavelength study of nuclear outflows in the nearby dwarf Seyfert galaxy NGC~4395, which hosts an intermediate-mass black hole. Using \textit{JWST}/NIRSpec and MI…
PRISMS. UNCOVER-26185, a metal-poor SFG at z=10.05 with no evidence for a X-ray-luminous AGN
J. Álvarez-Márquez, L. Colina, A. Crespo-Gomez +31
This work presents the first results of the PRImordial galaxy Survey with MIRI Spectroscopy (PRISMS), a JWST cycle 4 program (PID 8051) aimed at the characterization of a relativel…
PRISMS. U37126, a very blue, ISM-naked starburst at z=10.255 with nearly 100% Lyman continuum escape fraction
R. Marques-Chaves, J. Álvarez-Márquez, L. Colina +31
We present very deep (~11h) JWST/MIRI low-resolution spectroscopy of the rest-frame optical emission of U37126, a UV-bright (M_UV ~ -20), mildly lensed () galaxy at z=…
A UV-Luminous Galaxy at z=11 with Surprisingly Weak Star Formation Activity
Yuichi Harikane, Pablo G. Perez-Gonzalez, Javier Alvarez-Marquez +8
One of the major discoveries by the James Webb Space Telescope (JWST) is the identification of a large population of luminous galaxies at , challenging theoretical models for…
