A cosmic collision in the making: JWST/NIRISS reveals a merging and maturing protocluster core at z~3 around a red quasar
C. Bertemes, D. Wylezalek, G. Noirot +10
We report the discovery of ``The Step'', a dense protocluster at z=3 revealed by JWST/NIRISS Wide-Field Slitless Spectroscopy (WFSS) of the field around the luminous quasar and sta…
First Results from the JWST Early Release Science Program Q3D: AGN Photoionization and Shock Ionization in a Red Quasar at
Swetha Sankar, Nadia L. Zakamska, David S. N. Rupke +12
Red quasars, often associated with powerful [O III] outflows on both galactic and circumgalactic scales, may play a pivotal role in galaxy evolution and black hole feedback. In thi…
JWST Observations of Starbursts: Molecular Hydrogen Excitation and Disequilibrium in M82
Sara E. Duval, J. D. T. Smith, Alberto D. Bolatto +24
Emission from the pure rotational transitions of H traces warm molecular gas, providing insight into its temperature distribution and local heating conditions. We have extended…
JWST Observations of Starbursts: Dust Processing in the M82 Superwind
Serena A. Cronin, Alberto D. Bolatto, Helena M. Richie +39
We present JWST MIRI and NIRCam imaging of the inner ~5 kpc of the M82 superwind at 0.05-0.375'' (~0.9-6.5 pc) resolution. Targeted filters probe emission from polycyclic aromatic…
Kinematic Stratification in Extremely Red Quasars Revealed by JWST
Jack M. M. Neustadt, Nadia L. Zakamska, Yu-Ching Chen +7
We analyze the spectra of the central nuclei of extremely red quasars (ERQs) observed as part of the JWST ERS Q3D program. We focus on the complex kinematic structures of the promi…
Extreme Galaxy-scale Outflows Are Frequent among Luminous Early Quasars
Weizhe Liu, Xiaohui Fan, Huan Li +23
The existence of abundant post-starburst/quiescent galaxies just 1-2 Gyrs after the Big Bang challenges our current paradigm of galaxy evolution. Cosmological simulations sug…
