Mapping gas accretion and stellar kinematics to sub-kiloparsec scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
Strong LensIng and Cluster Evolution (SLICE) with JWST: Early Results, Lens Models, and High-Redshift Detections
Catherine Cerny, Guillaume Mahler, Keren Sharon +24
We leverage JWST's superb resolution to derive strong lensing mass maps of 14 clusters, spanning a redshift range of and a mass range of $M_{500}\sim2-12 \times…
HST view of NGC 5044: Constraints on Filament Widths, Magnetic Support, Multiphase Structure, and Comparison with Cluster Environments
Prathamesh Tamhane, Ming Sun, William Waldron +12
We present new Hubble Space Telescope (HST) imaging of ionised filaments in the brightest group galaxy NGC 5044. These filaments extend several kiloparsecs and have widths of $\sim…
Cold Gas and Star Formation in the Phoenix Cluster with JWST
Michael Reefe, Michael McDonald, Marios Chatzikos +16
We present integral field unit observations of the Phoenix Cluster with the JWST Mid-infrared Instrument's Medium Resolution Spectrometer (MIRI/MRS). We focus this study on the mol…
Directly Imaging the Cooling Flow in the Phoenix Cluster
Michael Reefe, Michael McDonald, Marios Chatzikos +14
In the centers of many galaxy clusters, the hot (10 K) intracluster medium (ICM) can become dense enough that it should cool on short timescales. However, the low measure…
