High-spectral-resolution Observations of the [S II] Emission-line Doublet in the Filamentary Nebula Surrounding NGC 1275
Benjamin Vigneron, Julie Hlavacek-Larrondo, Carter Lee Rhea +10
We analyze new high-spectral resolution SITELLE observations (R = = 7000) of the filamentary nebula surrounding NGC 1275, central galaxy of the Perseus cluster. We present h…
Constraining star formation in M87 using deep HST UV data
Prathamesh Tamhane, William Waldron, Ming Sun +11
We analyzed the deepest Hubble Space Telescope (HST) F275W ultraviolet (UV) imaging of M87 to obtain the most robust constraints on its star formation rate (SFR) and star formation…
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…
Mapping the Filamentary Nebula of NGC 1275 with Multiwavelength SITELLE Observations
Carter Lee Rhea, Julie Hlavacek-Larrondo, Marie-Lou Gendron-Marsolais +11
The filamentary nebula encompassing the central galaxy of the Perseus Cluster, NGC 1275, is a complex structure extending dozens of kiloparsecs from NGC 1275. Decades of previous w…
Star Formation, Nebulae, and Active Galactic Nuclei in CLASH Brightest Cluster Galaxies. I. Dependence on Core Entropy of Intracluster Medium
Arsen Levitskiy, Jeremy Lim, Youichi Ohyama +2
We set the stage for reassessing how star formation, emission-line nebulae, and active galactic nuclei (AGNs) in brightest cluster galaxies (BCGs) depend on the thermodynamics of t…
Equilibrium States of Galactic Atmospheres II: Interpretation and Implications
G. M. Voit, C. Carr, D. B. Fielding +5
The scaling of galaxy properties with halo mass suggests that feedback loops regulate star formation, but there is no consensus yet about how those feedback loops work. To help cla…
