GATOS: Distinct Feedback Modes in AGN Central Regions Revealed by Spatially Resolved JWST Spectroscopy
Lulu Zhang, Chris Packham, Erin K. S. Hicks +25
This manuscript presents JWST MIRI/MRS observations of the central pc regions of five active galactic nuclei (AGN) spanning a wide range of luminosities (${\rm l…
GATOS XIV: The first direct kinematic evidence of dusty outflows from AGN via PAH kinematics of local Seyfert galaxies with JWST
Fergus R. Donnan, Ismael GarcÃa-Bernete, Dimitra Rigopoulou +30
We present the first spatially resolved kinematic evidence for dust in the outflows of Active Galactic Nuclei (AGN). We utilise observations from JWST with NIRSpec IFU and MIRI MRS…
The free-streaming length of dark matter from JWST observations of 28 strong gravitational lenses
D. Gilman, A. M. Nierenberg, T. Treu +24
The formation of gravitationally bound overdensities of dark matter (DM), or \textit{halos}, is a generic prediction of theories with particle DM. We present a measurement of halo…
Decoupling the AGN outflow and star-forming disk kinematics in the nuclear region of NGC 7582 with JWST NIRSpec and MIRI/MRS
Oscar Veenema, Niranjan Thatte, Dimitra Rigopoulou +24
We present a detailed study of the inner regions of NGC~7582, a nearby Seyfert~2 galaxy, from the Galaxy Activity, Torus and Outflow Survey (GATOS). The galaxy hosts a circumnuclea…
JWST reveals the diversity of nuclear obscuring dust in nearby AGN: nuclear isolation of MIRI/MRS datacubes and continuum spectral fitting
Omaira González-MartÃn, Daniel J. DÃaz-González, Mariela MartÃnez-Paredes +22
We investigate the capabilities of the mid-infrared instrument (MIRI) of James Webb Space Telescope (JWST) to advance our knowledge of AGN dust using the spectral fitting technique…
Measurement of the minimum cold dark matter halo mass with strong gravitational lensing
A. M. Nierenberg, D. Gilman, T. Treu +19
We explore the lowest mass limit that can be placed on the halo mass function in CDM using 28 strong gravitational lenses. For this purpose, we study an extreme model in which the…
