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…
Impact of stochastic star-formation histories and dust on selecting quiescent galaxies with JWST photometry
K. Lisiecki, D. Donevski, A. W. S. Man +16
While the James Webb Space Telescope (JWST) now allows identifying quiescent galaxies (QGs) out to early epochs, the photometric selection of quiescent galaxy candidates (QGCs) and…
Black holes in the low-mass galaxy regime: imprint of AGN feedback on the circumgalactic medium of central dwarf galaxies
R. Flores-Freitas, D. Wylezalek, M. Trevisan +7
Active galactic nuclei (AGN) have been observed in dwarf galaxies, yet the impact of black hole feedback in these low-mass systems remains unclear. To uncover the potential effects…
JWST IFU observations uncover host galaxy continua in extremely red and obscured quasars
Yu-Ching Chen, Nadia L. Zakamska, Andrey Vayner +9
Uncovering bright quasars' host galaxies at cosmic noon is challenging because of the high contrast between the quasar and its host and redshifted light, making them primarily visi…
Resolving turbulence drivers in two luminous obscured quasars with JWST/NIRSpec IFU
Mandy C. Chen, Hsiao-Wen Chen, Michael Rauch +10
In this Letter, we investigate the turbulence and energy injection in the extended nebulae surrounding two luminous obscured quasars, WISEA J100211.29013706.7 () and S…
